Medical Disclaimer This article is for educational purposes only and does not replace medical advice, diagnosis, or treatment. Craniosynostosis surgery decisions depend on your child’s age, suture pattern, skull shape, head growth, pressure risk, eye findings, imaging, genetic evaluation, and craniofacial team recommendations. Always talk with your child’s pediatrician, pediatric neurosurgeon, craniofacial plastic surgeon, anesthesiologist, ophthalmologist, or healthcare professional about your child’s individual situation.

Parents often wonder:
- What actually happens during open craniosynostosis surgery?
- Is this brain surgery?
- Why would my baby need open surgery instead of endoscopic surgery?
- Will the surgeons remove part of the skull?
- How is the skull reshaped?
- Will my baby need a blood transfusion?
- Will my baby go to the ICU?
- How swollen will my baby look afterward?
- Will my baby need a helmet?
- How long is recovery?
- What can go wrong?
The clearest answer is:
Open cranial vault remodeling is a traditional craniosynostosis surgery in which a craniofacial plastic surgeon and pediatric neurosurgeon expose the skull through a larger scalp incision, release or remove the fused suture area, reshape the skull bones directly, and secure the bones in a new position to create more room for brain growth and a more typical head shape.
Unlike endoscopic strip craniectomy, which removes the fused suture and then relies heavily on helmet therapy and growth afterward, open cranial vault remodeling reshapes the skull during the operation itself. Because of that, a helmet is usually not needed after open cranial vault remodeling. Mayo Clinic states that open surgery is generally done for babies older than 6 months, involves reshaping the skull to allow more room for brain growth, usually requires a blood transfusion, and typically involves a 3- to 4-day hospital stay. Mayo also notes that helmet therapy is usually not needed after open surgery. (Mayo Clinic)
Open surgery sounds frightening, but it is a well-established craniosynostosis treatment. Johns Hopkins describes cranial vault remodeling, also called calvarial vault remodeling or reconstruction, as an open surgical approach that has been used for decades to treat craniosynostosis. (Johns Hopkins Medicine)
This guide explains what happens before, during, and after open cranial vault remodeling in parent-friendly language.
Quick Answer: What Is Open Cranial Vault Remodeling?
Open cranial vault remodeling is surgery that reshapes the skull bones directly.
The word cranial refers to the skull.The word vault refers to the skull bones that form the upper protective space around the brain.The word remodeling means the bones are reshaped and repositioned.
In craniosynostosis, one or more skull sutures close too early. That can restrict growth in one direction and cause the skull to grow in a long, narrow, triangular, flat, short-wide, asymmetric, or complex shape.
Open cranial vault remodeling treats this by:
- Releasing the fused suture restriction
- Creating more space for brain growth
- Reshaping the skull bones
- Improving head shape
- Reducing or preventing pressure concerns when appropriate
- Improving forehead, brow, eye-socket, or back-of-head shape depending on the suture involved
Johns Hopkins explains that the goal of craniosynostosis surgery is to expand the skull, relieve pressure inside it, and make room for brain growth. (Johns Hopkins Medicine)
The patient-friendly takeaway:
Open surgery reshapes the skull during the operation. Endoscopic surgery releases the suture and relies more on helmet-guided growth afterward.
Why Is It Called “Open” Surgery?
It is called open surgery because the surgeons make a larger scalp incision so they can directly see and reshape the skull bones.
Texas Children’s explains that open cranial vault remodeling is called “open” because the surgeon uses a coronal incision to see the skull and reshape it directly. (Texas Children’s)
Many centers use a zig-zag or wavy incision across the top of the scalp from one side of the head to the other. This incision is usually placed in a way that hair can cover it as the child grows. Seattle Children’s describes open cranial vault reconstruction as starting with a zig-zag incision over the top of the baby’s head, from one temple area to the other. (Seattle Children's)
The practical message:
“Open” does not mean the brain is exposed for surgery on the brain. It means the skull bones are accessed directly so they can be reshaped.
Is Open Cranial Vault Remodeling Brain Surgery?
This is one of the most common parent fears.
Open cranial vault remodeling is usually surgery on the skull bones around the brain, not surgery on the brain tissue itself.
A pediatric neurosurgeon is involved because the skull bones sit directly over the brain’s protective covering, called the dura. The neurosurgeon helps safely separate the skull bone from the dura and protect the brain while the craniofacial plastic surgeon reshapes the skull.
Seattle Children’s describes the neurosurgeon as making small holes in the skull and carefully separating the dura from the bone, while the plastic surgeon reshapes the bone. (Seattle Children's) Texas Children’s similarly explains that the pediatric neurosurgeon separates the dura from the bone and protects the brain while the craniofacial surgeon makes the bone cuts and reshapes the skull. (Texas Children’s)
The simple explanation:
The surgery is near the brain, so neurosurgical expertise is essential. But the main operation is skull reshaping, not operating on brain tissue.
Why Would Open Surgery Be Recommended?
Open cranial vault remodeling may be recommended when:
- The baby is older than the endoscopic surgery window
- The head shape needs more direct reshaping
- The suture type is better treated with open reconstruction
- The baby has metopic or coronal craniosynostosis involving the forehead or eye sockets
- More than one suture is fused
- The case is syndromic or complex
- The family cannot manage months of helmet therapy
- The expected result is more predictable with open surgery
- Endoscopic surgery is not expected to provide enough correction
- The child is diagnosed later
- There is concern for pressure, eye protection, or more complex skull growth
Mayo Clinic states that open surgery is generally done for babies older than 6 months and that the surgeon reshapes the skull to allow more room for brain growth. Mayo also notes that in complex craniosynostosis, more than one open surgery may be needed. (Mayo Clinic)
Cook Children’s describes open cranial vault remodeling as more customizable than endoscopic surgery, useful for older children, better for more challenging cases, and more predictable in some situations. (cookchildrens.org)
The parent-friendly takeaway:
Open surgery is not a “worse” option. It is often the right option when the skull needs direct reshaping or when the baby is older, the suture type is complex, or helmet-based correction is not ideal.
Open Surgery vs Endoscopic Surgery
Open and endoscopic surgery both treat craniosynostosis, but they work differently.

Results
More immediate visible change
Gradual change over months with helmet
Seattle Children’s compares the approaches by noting that open cranial vault surgery may take 3 to 5 hours, is likely to require a blood transfusion, and often involves a 3- to 5-day hospital stay including 1 ICU day; endoscopic surgery is shorter, less likely to require transfusion, and usually has a shorter hospital stay. (Seattle Children's) ASPS notes that open procedures reposition the skull bones and usually produce a significant immediate change in head shape, while strip craniectomy relies on custom helmet therapy after surgery to improve shape over time. (American Society of Plastic Surgeons)
The practical message:
Endoscopic surgery is smaller up front but requires helmet therapy. Open surgery is larger up front but reshapes the skull directly and usually does not require a helmet.
What Age Is Open Cranial Vault Remodeling Done?
There is no single age for every baby.
Timing depends on:
- Which suture is fused
- How severe the head shape is
- Whether one or multiple sutures are involved
- Whether the case is syndromic
- Whether the front or back of the skull needs reshaping
- Whether pressure or eye concerns are present
- The craniofacial team’s approach
Mayo Clinic states that open surgery is generally done for babies older than 6 months. (Mayo Clinic) Johns Hopkins describes cranial vault remodeling as typically performed between 6 and 12 months, while also noting it can be an option for children diagnosed later or babies with severe craniosynostosis. (Johns Hopkins Medicine)
Some centers use different timing based on suture type. Seattle Children’s states that open cranial vault reconstruction for a fused sagittal suture is done when a baby is 3 to 6 months old, lambdoid surgery is done at 9 to 12 months, and fronto-orbital advancement for metopic or coronal sutures often takes place around 9 to 12 months depending on the suture. (Seattle Children's) Texas Children’s gives similar center-specific timing, with preferred open vault remodeling for the back of the head around 4 to 6 months and fronto-orbital advancement around 10 to 12 months. (Texas Children’s)
The parent-friendly takeaway:
Open surgery timing depends on the suture and surgical goal. A timing recommendation for sagittal craniosynostosis may not apply to metopic, coronal, lambdoid, bicoronal, or multisuture craniosynostosis.
What Happens Before Surgery?
Before open cranial vault remodeling, families usually meet with the craniofacial team to review the diagnosis, surgical plan, risks, benefits, and hospital course.
Before surgery, your child may have:
Physical exam
Head measurements
Photos
CT scan or 3D imaging if needed
Blood work
Blood type and crossmatch
Anesthesia evaluation
Neurosurgery consultation
Craniofacial plastic surgery consultation
Eye exam if pressure or orbit concerns exist
Genetics evaluation if syndromic craniosynostosis is possible
Preoperative instructions about feeding, bathing, and medicines
ASPS notes that preoperative preparation may include lab testing, crossmatch for possible blood transfusion, imaging such as CT, and meeting with a multidisciplinary team. ASPS also recommends asking whether the surgeon is part of a multidisciplinary craniofacial team and whether surgery is done at a specialized children’s hospital with pediatric anesthesiologists. (American Society of Plastic Surgeons)
The practical message:
Open cranial vault remodeling is planned carefully. Parents should know who is on the team, what imaging is being used, whether blood transfusion is likely, and what the hospital stay will look like.
Who Is in the Operating Room?
The exact team varies by hospital, but open craniosynostosis surgery usually involves:
- Pediatric neurosurgeon
- Craniofacial plastic surgeon
- Pediatric anesthesiologist
- Operating room nurses
- Surgical technologists
- Blood bank support if transfusion is needed
- Sometimes trainees, physician assistants, or nurse practitioners depending on the center
Mayo Clinic states that craniosynostosis surgery is usually done by a team that includes a craniofacial surgeon and a neurosurgeon. (Mayo Clinic) ASPS states that craniosynostosis surgery should be performed by a plastic surgeon and pediatric neurosurgeon experienced in craniosynostosis care, with support from a pediatric anesthesiologist at a center that performs this surgery regularly. (American Society of Plastic Surgeons)
The parent-friendly takeaway:
Open craniosynostosis surgery is a team operation. The neurosurgeon protects the brain and dura; the craniofacial plastic surgeon reshapes the skull.
What Happens During Open Cranial Vault Remodeling?
The exact details depend on the suture and surgical plan, but many open cranial vault surgeries include these general steps.
1. Anesthesia
Your baby receives general anesthesia so they are asleep, pain-free, and carefully monitored during surgery.
The anesthesia team monitors breathing, heart rate, blood pressure, temperature, fluids, and blood loss throughout the operation.
2. Scalp incision
The surgical team makes an incision across the scalp. Many centers use a zig-zag or wavy incision from one side of the head to the other so the scar can be hidden by hair over time.
Texas Children’s describes the incision as a zig-zag cut over the top of the baby’s head from one temple to the other. (Texas Children’s)
3. Soft tissue is lifted
The craniofacial plastic surgeon separates the skin and soft tissue from the skull bone underneath so the skull can be seen and marked.
Seattle Children’s describes the plastic surgeon separating the skin and soft tissue from the bone and marking the pattern of bone cuts that will allow the skull shape to change. (Seattle Children's)
4. Skull bone is released safely
The neurosurgeon makes small openings in the skull and carefully separates the dura, the brain’s protective covering, from the skull bone.
Seattle Children’s and Texas Children’s both describe this neurosurgical step as separating the dura from the bone so the skull can be safely reshaped. (Seattle Children's)
5. Bone cuts are made
The surgeons make planned cuts in the skull bones based on the child’s anatomy and the shape correction needed.
6. Skull bones are reshaped
The skull bones may be bent, repositioned, removed and rebuilt, or reshaped with specific techniques depending on whether the front, back, or entire skull vault is being corrected.
Johns Hopkins explains that the affected bones may be in the front, back, or middle of the skull, and that surgeons reshape and replace the bones to improve head shape and increase space for the developing brain. (Johns Hopkins Medicine)
7. Bones are secured
The reshaped bones are secured using dissolving plates, screws, sutures, or other materials depending on the center and procedure.
Seattle Children’s states that plates and screws may be used to hold the shape during healing and that these typically dissolve completely in 1 to 2 years; rarely, small wires may be used for added strength. (Seattle Children's) Mayo Clinic also notes that the skull position is held with plates and screws that dissolve over time. (Mayo Clinic)
8. Incision is closed
The scalp is closed, usually with dissolving stitches or a closure method chosen by the surgical team.
Texas Children’s states that the incision is closed with dissolving sutures and antibiotic ointment may be used afterward. (Texas Children’s)
The practical message:
Open surgery reshapes the skull directly. The surgeons do not simply remove the fused suture; they reconstruct the skull into a better shape and position.
What Is Fronto-Orbital Advancement?
Fronto-orbital advancement , often shortened to FOA, is a type of open cranial vault surgery used when the forehead and upper eye-socket area need reshaping.
“Fronto” refers to the forehead.“Orbital” refers to the eye sockets.“Advancement” means moving the bones forward or into a new position.
FOA may be recommended for:
- Metopic craniosynostosis with significant trigonocephaly
- Unicoronal craniosynostosis
- Bicoronal craniosynostosis
- Some syndromic craniosynostosis cases
- Forehead and upper eye-socket restriction
- Eye protection concerns in selected cases
Johns Hopkins explains that when the front part of the skull needs reshaping, the operation is called fronto-orbital advancement, in which the forehead and eye-socket bones are reshaped and repositioned to allow more room in the front of the head. (Johns Hopkins Medicine) Seattle Children’s states that fronto-orbital advancement moves and reshapes the forehead and upper eye sockets, creating more space for the brain and more protection for the eyes. (Seattle Children's)
The parent-friendly takeaway:
FOA is open surgery focused on the forehead and upper eye sockets. It is common in metopic and coronal craniosynostosis discussions.
What Is Posterior Cranial Vault Remodeling?
Posterior cranial vault remodeling or posterior vault expansion means the back part of the skull is reshaped or expanded.
It may be considered when:
- The back of the skull is restricted
- Lambdoid craniosynostosis is present
- A baby has sagittal craniosynostosis requiring back/top reshaping
- The child has multisuture or syndromic craniosynostosis
- More room is needed at the back of the skull
- Pressure risk is a concern in selected complex cases
Johns Hopkins describes posterior cranial vault remodeling or posterior vault expansion as the term used when the back part of the skull needs reshaping. (Johns Hopkins Medicine)
Texas Children’s explains that when the back of the head needs reshaping, surgeons may gently bend bone into a new curve using “barrel stave” techniques, commonly used for conditions such as sagittal and lambdoid synostosis. (Texas Children’s)
The practical message:
Posterior vault surgery focuses on the back of the skull. FOA focuses on the forehead and upper eye sockets. Some complex cases may need staged surgery involving both areas over time.
What Is Total Vault Remodeling?
Total vault remodeling means a larger portion of the upper skull vault is reshaped.
This may be discussed in more complex cases, severe head-shape deformity, multisuture craniosynostosis, syndromic craniosynostosis, or when multiple areas of the skull need correction.
Johns Hopkins explains that sometimes the entire top of the skull must be reshaped, which is called total vault remodeling. (Johns Hopkins Medicine)
The parent-friendly takeaway:
Total vault remodeling is a broader open skull reshaping operation, usually reserved for more extensive skull-shape needs.
How Long Does Open Cranial Vault Remodeling Take?
Surgery time varies by hospital, suture type, child age, and complexity.
Johns Hopkins states that cranial vault remodeling surgery takes about 4 to 6 hours. (Johns Hopkins Medicine) Seattle Children’s lists open cranial vault surgery as about 3 to 5 hours in its comparison with endoscopic strip craniectomy. (Seattle Children's)
The practical message:
Ask your team for the expected operating room time, but remember that operating room time includes anesthesia setup, positioning, surgery, and safe wake-up — not just bone reshaping time.
Will My Baby Need a Blood Transfusion?
A blood transfusion is more common with open cranial vault remodeling than with endoscopic surgery because open surgery involves more extensive bone reshaping and can involve more blood loss.
Mayo Clinic states that blood transfusion is usually needed for open craniosynostosis surgery. (Mayo Clinic) Johns Hopkins states that a blood transfusion is often needed during cranial vault remodeling. (Johns Hopkins Medicine) Seattle Children’s says open cranial vault surgery is likely to require a blood transfusion in its comparison table. (Seattle Children's)
Parents should ask:
- Is transfusion expected in my child’s surgery?
- Will blood be crossmatched before surgery?
- Do you use blood-conservation strategies?
- What are the risks of transfusion?
- Can parents donate blood?
- What happens if transfusion is needed urgently?
The parent-friendly takeaway:
Blood transfusion is a common topic in open craniosynostosis surgery planning. It does not mean something has gone wrong, but parents should understand the plan.
Will My Baby Go to the ICU?
Many babies spend at least one night in the ICU or pediatric intensive care unit after open cranial vault remodeling.
This does not always mean something bad has happened. The ICU allows close monitoring after a major operation, especially during the first night.
Seattle Children’s states that most babies spend 3 to 5 nights in the hospital after open cranial vault reconstruction, including 1 night in the ICU. (Seattle Children's) Johns Hopkins states that the child will likely spend one night in intensive care plus a few additional days in the hospital for monitoring. (Johns Hopkins Medicine) Texas Children’s also describes most babies spending 3 to 5 nights in the hospital, including 1 night in the PICU. (Texas Children’s)
The practical message:
ICU after open craniosynostosis surgery is often planned monitoring, not necessarily a sign of a complication.
How Long Is the Hospital Stay?
Hospital stay varies, but many centers describe several days in the hospital after open cranial vault remodeling.
Mayo Clinic states that open surgery typically involves a hospital stay of 3 to 4 days. (Mayo Clinic) Seattle Children’s and Texas Children’s describe 3 to 5 nights in the hospital, including one ICU night. (Seattle Children's)
Discharge usually depends on:
- Stable vital signs
- Pain controlled with medicines that can be given at home
- Baby feeding well enough
- No concerning bleeding or wound issues
- Swelling is expected and manageable
- The team is comfortable with neurologic checks
- Parents understand incision care and warning signs
The parent-friendly takeaway:
Open surgery usually means several days in the hospital. The first night is often the most closely monitored.
Will My Baby Need a Helmet After Open Surgery?
Usually, no.
This is one of the major differences between open and endoscopic craniosynostosis surgery.
In open cranial vault remodeling, the surgeons reshape the skull bones directly during the operation. Because the new shape is created in surgery, helmet therapy is usually not needed afterward.
Mayo Clinic states that if open surgery is done, usually no helmet is needed afterward. (Mayo Clinic) Seattle Children’s states that after open cranial vault reconstruction, the child does not need a helmet to shape the head. (Seattle Children's) Johns Hopkins also states that helmet therapy is typically not needed after cranial vault remodeling. (Johns Hopkins Medicine)
The practical message:
Open surgery is bigger up front, but it usually avoids the months-long helmet schedule required after endoscopic surgery.
What Will My Baby Look Like After Surgery?
Parents should be prepared for swelling.
After open cranial vault remodeling, the baby’s head and face can look very swollen. The eyes may swell significantly and may even swell shut temporarily.
ASPS states that swelling after craniosynostosis surgery can be substantial and that the eyes may swell shut, which is a normal part of healing and usually resolves in 2 to 3 days. ASPS also notes that immediate swelling mostly improves over the first few days to weeks, although complete swelling resolution can take months. (American Society of Plastic Surgeons)
Parents may see:
- Swollen forehead or scalp
- Puffy eyelids
- Eyes swollen partly or fully shut
- Bruising
- Bandage or incision ointment
- A different head shape immediately
- Baby looking groggy or tired
- Temporary feeding changes
The parent-friendly takeaway:
The swelling can look shocking, especially around the eyes, but it is often expected after open cranial vault surgery. Ask your team what is normal and what is not.
When Will the Head Shape Look Different?
With open surgery, the head shape often looks different right away, though swelling can hide the final contour at first.
ASPS states that open craniosynostosis procedures release fused sutures and reposition skull bones, and the results are immediately apparent with a significant change in head shape from before to after surgery. (American Society of Plastic Surgeons)
However, parents should remember:
- Swelling can distort the early appearance.
- The head shape continues to settle as swelling goes down.
- Bone healing and remodeling continue over time.
- Small irregularities or soft spots may improve as the skull heals.
ASPS notes that slight irregularities or soft spots may be present after surgery and can improve over time as the skull bones remodel and heal. (American Society of Plastic Surgeons)
The practical message:
The shape may change immediately, but the final result is judged over months, not in the first swollen days after surgery.
What About the Scar?
Open cranial vault remodeling usually involves a longer scalp incision. Many centers use a zig-zag or wavy incision so the scar blends better with hair as the child grows.
Seattle Children’s notes that open surgery has a larger scar than endoscopic surgery, but it is usually covered by hair within months. (Seattle Children's)
Parents should ask:
- Where will the incision be?
- Will it be straight, wavy, or zig-zag?
- How is it closed?
- Will stitches dissolve?
- When can we wash hair?
- How should incision care be done?
- What scar changes are normal?
- What signs suggest infection?
- Will the scar be visible when hair grows?
The patient-friendly takeaway:
The incision is longer than endoscopic surgery, but teams usually plan it so hair can hide it over time.
What Are Resorbable Plates and Screws?
During open surgery, the surgeons may use plates, screws, or sutures to hold reshaped skull bones in place while healing occurs.
Many centers use resorbable or dissolvable plates and screws. These gradually break down over time.
Seattle Children’s states that plates and screws may be used to hold the shape during healing and that they dissolve completely in 1 to 2 years; rarely, small surgical wires may be used for extra strength and do not dissolve. (Seattle Children's) Texas Children’s also describes securing rebuilt bone with resorbable plates and screws or dissolving sutures. (Texas Children’s)
The practical message:
Ask your team what materials will be used, whether they dissolve, whether they can be felt under the scalp, and whether they ever need removal.
What Are “Barrel Staves”?
Parents may hear the term barrel staves during discussions of posterior or sagittal skull reshaping.
A barrel stave technique involves making cuts in skull bone that allow it to bend into a new curve, somewhat like the curved wooden staves of a barrel.
Texas Children’s explains that when the back of the head needs reshaping, the bone may be gently bent into a new position with special tools, and these cuts are called barrel staves because they create a new skull curve like the side of a barrel. (Texas Children’s)
The parent-friendly takeaway:
Barrel staves are a skull-reshaping technique. They help the surgeons curve and expand the skull rather than simply remove bone.
Why Open Surgery May Be Chosen for Older Babies
Open surgery is often chosen for older babies because the skull bones are thicker, growth is slower, and helmet-guided reshaping may be less effective than in early infancy.
Seattle Children’s states that for babies older than 4 months with sagittal or lambdoid suture fusion, it recommends open cranial vault reconstruction because skull growth slows at 5 months and helmet therapy becomes less effective. (Seattle Children's) Mayo Clinic states more broadly that open surgery is generally done for babies older than 6 months. (Mayo Clinic)
The practical message:
Open surgery is often the preferred treatment when the child is beyond the age where helmet-guided endoscopic correction is expected to work well.
Why Open Surgery May Be Chosen for Metopic or Coronal Craniosynostosis
Metopic and coronal craniosynostosis often affect the forehead, brow, and upper eye sockets. These areas may need direct reshaping.
For example:
- Metopic craniosynostosis can cause a triangular forehead.
- Unicoronal craniosynostosis can cause one-sided forehead, brow, and eye-socket asymmetry.
Bicoronal craniosynostosis can cause a short, wide, tall head shape with forehead and orbital changes.
Seattle Children’s states that it often recommends open fronto-orbital advancement for babies with fused metopic or coronal sutures, usually around 9 to 12 months depending on the suture. (Seattle Children's) Johns Hopkins describes fronto-orbital advancement as reshaping and repositioning the forehead and eye-socket bones to allow more room in the front of the head. (Johns Hopkins Medicine)
The parent-friendly takeaway:
When craniosynostosis affects the forehead or eye sockets, open surgery may be recommended because the bones need direct reshaping.
Why Open Surgery May Be Chosen for Complex or Syndromic Craniosynostosis
Complex craniosynostosis may involve multiple sutures, genetic syndromes, pressure concerns, eye protection, airway issues, or staged operations.
Open cranial vault remodeling is often used when smaller-incision options are not expected to provide enough correction or may be less safe.
Texas Children’s states that open cranial vault remodeling is usually used for more complex craniosynostosis, such as craniofacial syndromes, or in older children when smaller-incision surgeries such as endoscopic strip craniectomy or spring cranioplasty are not effective. Texas Children’s also states it recommends open remodeling in complex conditions when smaller-incision surgery is considered more dangerous or unlikely to provide the same results. (Texas Children’s)
Mayo Clinic notes that open surgery is generally a one-time procedure, but babies with complex craniosynostosis often need more open surgeries to reshape the head. (Mayo Clinic)
The practical message:
In complex or syndromic craniosynostosis, open surgery may be part of a staged plan rather than a single one-time event.
What Are the Benefits of Open Cranial Vault Remodeling?
Possible benefits include:
- Direct skull reshaping during surgery
- Immediate visible improvement in head shape
- Ability to treat older babies and children
- Ability to address more severe or complex skull shapes
- Ability to reshape forehead, eye sockets, back of skull, or entire skull vault
- Usually no helmet afterward
- More customization than endoscopic surgery in many cases
- Useful for metopic, coronal, multisuture, or syndromic cases when needed
Cook Children’s lists benefits of open cranial vault remodeling as being usable in older children, not requiring a corrective helmet afterward, being more customizable than endoscopic surgery, being better for more challenging cases, and producing more predictable results. (cookchildrens.org) ASPS notes that open procedures create an immediately apparent head-shape change because the skull bones are repositioned during surgery. (American Society of Plastic Surgeons)
The parent-friendly takeaway:
Open surgery is larger, but it gives the surgeons direct control over skull shape during the operation.
What Are the Tradeoffs of Open Surgery?
Open surgery also has tradeoffs.
Compared with endoscopic surgery, open surgery often involves:
- A longer incision
- Longer surgery time
- More blood loss
- Higher likelihood of blood transfusion
- More swelling
- Longer hospital stay
- ICU monitoring
- More immediate recovery burden
Mayo Clinic states that open surgery typically involves a 3- to 4-day hospital stay and that blood transfusion is usually needed. (Mayo Clinic) Seattle Children’s describes open surgery as 3 to 5 hours, likely to require transfusion, and usually involving a 3- to 5-day hospital stay with 1 ICU day. (Seattle Children's)
The practical message:
Open surgery usually involves a bigger early recovery, but it may avoid months of helmet therapy and may be the best way to achieve the needed skull correction.
What Are the Risks of Open Cranial Vault Remodeling?
Every surgery has risks. Open cranial vault remodeling is major surgery, so parents should understand both common expected issues and less common complications.
Possible risks include:
Anesthesia risks
Bleeding
Blood transfusion risks
Infection
Swelling and bruising
Eyes swelling shut temporarily
Pain
Scalp numbness or altered sensation
Dura injury
Leakage of cerebrospinal fluid, or CSF
Incomplete correction of head shape or eye position
Persistent skull gaps
Need for revision surgery
Recurrence of raised intracranial pressure
Unfavorable scarring
Very rare serious risks such as blindness or death
ASPS lists these risks and emphasizes that families should discuss them directly with the plastic surgeon and neurosurgeon before consent. (American Society of Plastic Surgeons) Johns Hopkins notes that cranial vault remodeling is longer and more complex than endoscopic surgery and increases the likelihood of needing a blood transfusion, though care teams have protocols to identify and manage complications. (Johns Hopkins Medicine)
The patient-friendly takeaway:
Open cranial vault remodeling is common in craniosynostosis care, but it is still major surgery. Parents should feel comfortable asking direct questions about risks and how the team handles them.
What Is Normal After Open Surgery?
Your surgical team’s instructions matter most. In general, common early recovery experiences may include:
Sleepiness from anesthesia
Puffy face or eyelids
Eyes swelling partly or fully shut
Scalp swelling
Bruising
Temporary fussiness
Pain controlled with medication
Reduced appetite at first
Temporary changes in sleep
Incision tenderness
A dramatic change in head shape
ASPS states that eye swelling can be substantial and that eyes may swell shut temporarily, usually improving in 2 to 3 days. (American Society of Plastic Surgeons)
The practical message:
Parents often say the swelling looks worse than they expected. Ask your team to show examples or describe the swelling timeline before surgery.
When Should Parents Call After Surgery?
Follow your discharge instructions. In general, call your child’s surgical team promptly if your baby has:
Fever
Increasing redness around the incision
Drainage from the incision
Bleeding that does not stop as instructed
Worsening swelling after discharge
Repeated vomiting
Poor feeding
Unusual sleepiness or difficulty waking
Trouble breathing
Seizure-like activity
Bulging soft spot
Clear fluid leakage
New weakness or unusual movement
Signs of pain not controlled by medication
Any symptom your discharge instructions list as urgent
ASPS advises parents to ask about signs and symptoms to monitor after surgery, incision care, bathing, medicines, drains if used, helmet needs, follow-up, and whether additional procedures may be required. (American Society of Plastic Surgeons)
Seek urgent or emergency care if your baby is difficult to wake, has trouble breathing, has repeated vomiting, has seizure-like activity, or seems seriously ill.
What Does Follow-Up Look Like?
Follow-up schedules vary by center and child, but they often include:
- Early postoperative visit
- Incision check
- Head-shape evaluation
- Head circumference monitoring
- Developmental monitoring
- Eye exams when needed
- Longer-term craniofacial follow-up
- Additional imaging only if needed
Johns Hopkins states that after cranial vault remodeling, children follow up with the surgery team at about 1 month, 6 months, and 12 months after surgery to monitor the incision and recovery. (Johns Hopkins Medicine) ASPS notes that after craniosynostosis surgery, children are followed regularly by the craniofacial surgeon or craniofacial team to monitor immediate recovery and continued growth and development. (American Society of Plastic Surgeons)
The parent-friendly takeaway:
Surgery day is one step. Long-term follow-up helps the team make sure the skull continues to grow well and no new concerns appear.
Will My Child Need More Than One Surgery?
Many children with single-suture craniosynostosis need only one surgery. But some children may need more than one operation.
Additional surgery may be more likely when:
- Multiple sutures are fused
- The child has syndromic craniosynostosis
- The skull shape changes with growth
- Raised intracranial pressure returns or appears
- Persistent skull gaps require repair
- A revision is needed for incomplete correction
- Further facial or jaw surgery is needed later in syndromic cases
Seattle Children’s states that if only one suture is fused, most children need only one surgery, while babies with multiple fused sutures or genetic syndromes usually need a series of operations. (Seattle Children's) ASPS also notes that some children may require additional surgery in the future, including if signs of increased intracranial pressure recur or if persistent skull defects need repair. (American Society of Plastic Surgeons)
The practical message:
One surgery is common in straightforward single-suture cases, but complex or syndromic craniosynostosis often requires longer-term staged care.
How Should Parents Prepare Emotionally?
Open cranial vault remodeling is a lot for families to process.
It may help to remember:
- The surgery is planned, not rushed, in most cases.
- The team does this type of surgery regularly.
- The ICU stay is often planned monitoring.
- Swelling can look dramatic but often improves quickly.
- The head shape may look different right away.
- Most children need close follow-up, not constant intervention.
- Parents should ask every question they need answered.
Mayo Clinic notes that families may feel many emotions after learning a baby has craniosynostosis and encourages families to find trusted professionals, seek support, and work with craniofacial specialty teams that coordinate care. (Mayo Clinic)
The parent-friendly message:
You do not have to be calm because the surgery is easy. You can be scared and still make a thoughtful, informed plan with the surgical team.
Ask your craniofacial team:
- Which suture or sutures are fused?
- Why are you recommending open surgery?
- Is endoscopic surgery an option?
- Why is open surgery better for my baby?
- What type of open surgery is planned?
Is this cranial vault remodeling, fronto-orbital advancement, posterior vault remodeling, or total vault remodeling?
What are the goals of surgery?
Is the goal skull shape, brain space, pressure prevention, eye protection, facial symmetry, or a combination?
- How old should my baby be at surgery?
- How long will surgery take?
- Who will be in the operating room?
- Will both pediatric neurosurgery and craniofacial plastic surgery be involved?
- Will my baby need a blood transfusion?
- Will my baby go to the ICU?
- How long is the expected hospital stay?
- What swelling should we expect?
- Will my baby’s eyes swell shut?
- Will my baby need a helmet?
- What materials will hold the bones in place?
- Do the plates and screws dissolve?
- What will the scar look like?
- What are the risks?
- How are complications handled?
- Could another surgery be needed later?
- What follow-up will be needed?
ASPS provides a similar consultation checklist, including questions about the surgeon’s training, multidisciplinary craniofacial team, fused sutures, signs of genetic syndrome, signs of raised intracranial pressure, recommended technique, surgery age, recovery, risks, transfusion, ICU stay, head-shape changes, helmet use, and before-and-after photos. (American Society of Plastic Surgeons)
Ask:
- Where will my baby go immediately after surgery?
- How long will my baby be in the ICU?
- How will pain be controlled?
- Will there be drains?
- When are drains removed?
- Will there be a head wrap?
- How swollen will my baby look?
- When is swelling expected to peak?
- When should the eyes reopen if they swell shut?
- How should we care for the incision?
- When can we bathe our baby?
- When can we wash hair?
- What medicines will be prescribed?
- What symptoms should make us call?
- What symptoms require emergency care?
- When is the first follow-up visit?
- When can my baby return to normal activities?
- Will there be activity restrictions?
- Will my baby need physical therapy, helmeting, or other follow-up?
The practical takeaway:
Recovery instructions should be specific. Parents should leave the hospital knowing what is normal, what is not, and who to call.
Common Parent Fears
“Will my baby’s eyes swell shut?”
They might. This can be expected after open craniosynostosis surgery. ASPS states that the eyes may swell shut and that this is a normal part of healing, usually resolving in 2 to 3 days. (American Society of Plastic Surgeons)
“Will my baby need a helmet afterward?”
Usually not. Mayo Clinic, Seattle Children’s, and Johns Hopkins all state that helmet therapy is usually not needed after open cranial vault remodeling. (Mayo Clinic)
“Will my baby need a blood transfusion?”
Often, yes. Mayo Clinic states that blood transfusion is usually needed with open surgery, and Johns Hopkins states transfusion is often needed during cranial vault remodeling. (Mayo Clinic)
“Is open surgery more dangerous than endoscopic surgery?”
Open surgery is longer and more complex and is more likely to require transfusion, but it may be the better treatment for some babies. Johns Hopkins notes that endoscopic strip craniectomy and cranial vault remodeling generally have similar complication rates, though cranial vault remodeling is longer and more complex and increases the likelihood of blood transfusion. (Johns Hopkins Medicine)
“Will the scar be obvious?”
The incision is longer than with endoscopic surgery, but it is usually placed so hair covers it over time. Seattle Children’s notes that the larger scar is usually completely covered by hair within months. (Seattle Children's)
“Will my child need another surgery?”
Many single-suture cases need one surgery, but some children need more, especially complex or syndromic cases. Seattle Children’s states that babies with multiple fused sutures or genetic syndromes usually need a series of operations. (Seattle Children's)
How to Explain Open Cranial Vault Remodeling to Family
Here is a simple explanation:
“Open cranial vault remodeling is traditional craniosynostosis surgery. The surgeons make a larger incision across the scalp so they can see the skull directly. A pediatric neurosurgeon protects the brain covering while a craniofacial plastic surgeon reshapes the skull bones. The goal is to release the fused suture restriction, create more room for brain growth, and give the head a more typical shape. It is a bigger surgery than endoscopic surgery, but the skull is reshaped during the operation, so a helmet is usually not needed afterward.”
This can help relatives understand why open surgery may be recommended even when less invasive surgery exists.
Open cranial vault remodeling is traditional open craniosynostosis surgery.
It is also called open cranial vault reconstruction, calvarial vault remodeling, or cranial vault reconstruction.
The goal is to reshape the skull, create room for brain growth, and reduce or prevent pressure concerns when appropriate.
- It is usually surgery on the skull bones around the brain, not surgery on brain tissue itself.
- A pediatric neurosurgeon and craniofacial plastic surgeon often work together.
- The surgery usually uses a larger scalp incision, often zig-zag or wavy.
- The skull bones are released, reshaped, repositioned, and secured.
- Dissolving plates, screws, or sutures may be used.
Open surgery is often recommended for older babies, more severe head shapes, metopic or coronal craniosynostosis, forehead or eye-socket reshaping, complex cases, multisuture craniosynostosis, or syndromic craniosynostosis.
- Open surgery usually requires several days in the hospital and often includes one ICU night.
- Blood transfusion is more common with open surgery than endoscopic surgery.
- Swelling can be substantial, and the eyes may swell shut temporarily.
- A helmet is usually not needed after open surgery.
- The head shape often changes immediately, but swelling and bone healing continue over months.
Many children with single-suture craniosynostosis need one surgery, while complex or syndromic cases may need staged care.
The simplest parent-friendly summary is:
Open cranial vault remodeling is a direct skull-reshaping operation. It is bigger than endoscopic surgery, but it allows surgeons to correct the skull shape during the operation and usually avoids helmet therapy afterward.
Frequently Asked Questions About Open Cranial Vault Remodeling
What is open cranial vault remodeling?
Open cranial vault remodeling is a traditional craniosynostosis surgery in which surgeons reshape the skull bones directly to create more room for brain growth and improve head shape. Johns Hopkins describes it as an open surgical approach, also called calvarial vault remodeling or reconstruction, used for decades to treat craniosynostosis. (Johns Hopkins Medicine)
Why is it called open surgery?
It is called open surgery because the surgeon uses a larger scalp incision to see and reshape the skull directly. Texas Children’s explains that open vault remodeling uses a coronal incision so the surgeon can see the entire skull and reshape it directly. (Texas Children’s)
Is open cranial vault remodeling brain surgery?
It is usually surgery on the skull bones around the brain, not surgery on the brain tissue itself. The neurosurgeon helps protect the brain and dura while the craniofacial plastic surgeon reshapes the skull. (Seattle Children's)
Who performs open craniosynostosis surgery?
Open craniosynostosis surgery is usually performed by a pediatric neurosurgeon and a craniofacial plastic surgeon. Mayo Clinic states that surgery is usually done by a team including a craniofacial surgeon and neurosurgeon. (Mayo Clinic)
What age is open cranial vault remodeling done?
Timing varies by suture and center. Mayo Clinic states that open surgery is generally done for babies older than 6 months. Johns Hopkins describes cranial vault remodeling as typically performed between 6 and 12 months, while Seattle Children’s and Texas Children’s list suture-specific timing that may be earlier or later depending on the affected area. (Mayo Clinic)
Why would open surgery be recommended instead of endoscopic surgery?
Open surgery may be recommended if the baby is older, the head shape needs direct reshaping, the suture type affects the forehead or eye sockets, multiple sutures are involved, the case is syndromic or complex, or helmet therapy is not a good fit. Cook Children’s notes that open surgery can be used in older children, does not require a helmet, is more customizable, and may be better for more challenging cases. (cookchildrens.org)
What happens during open cranial vault remodeling?
The surgeons make a scalp incision, lift soft tissue from the skull, separate skull bone from the dura, make planned bone cuts, reshape the skull bones, secure them in a new position, and close the incision. Seattle Children’s and Texas Children’s both describe these core steps. (Seattle Children's)
What is fronto-orbital advancement?
Fronto-orbital advancement is open surgery that reshapes and moves the forehead and upper eye-socket bones. It is often discussed for metopic or coronal craniosynostosis. Johns Hopkins describes it as reshaping and repositioning the forehead and eye-socket bones to create more room in the front of the head. (Johns Hopkins Medicine)
What is posterior cranial vault remodeling?
Posterior cranial vault remodeling or posterior vault expansion reshapes or expands the back of the skull. Johns Hopkins uses this term when the back part of the skull needs reshaping. (Johns Hopkins Medicine)
What is total vault remodeling?
Total vault remodeling means the entire top of the skull is reshaped. Johns Hopkins notes that sometimes the whole top of the skull must be reshaped, which is called total vault remodeling. (Johns Hopkins Medicine)
How long does open craniosynostosis surgery take?
Surgery time varies. Johns Hopkins states that cranial vault remodeling takes about 4 to 6 hours. Seattle Children’s lists open cranial vault surgery as about 3 to 5 hours in its comparison with endoscopic surgery. (Johns Hopkins Medicine)
Will my baby need a blood transfusion?
Often, yes. Mayo Clinic states that blood transfusion is usually needed during open surgery, and Johns Hopkins states that transfusion is often needed during cranial vault remodeling. (Mayo Clinic)
How long is the hospital stay?
Hospital stay varies by center. Mayo Clinic states that open surgery typically involves a 3- to 4-day hospital stay. Seattle Children’s and Texas Children’s describe 3 to 5 nights in the hospital, including 1 ICU night. (Mayo Clinic)
Will my baby go to the ICU?
Many babies spend one night in the ICU after open cranial vault remodeling for close monitoring. This is often planned. Seattle Children’s, Texas Children’s, and Johns Hopkins all describe an ICU stay as part of the typical open surgery hospital course. (Seattle Children's)
Will my baby need a helmet after open surgery?
Usually no. Mayo Clinic states that after open surgery, usually no helmet is needed. Seattle Children’s and Johns Hopkins also state that helmet therapy is typically not needed after open cranial vault reconstruction. (Mayo Clinic)
How swollen will my baby be after surgery?
Swelling can be substantial. ASPS states that the eyes may swell shut after craniosynostosis surgery, which is a normal part of healing and usually resolves in 2 to 3 days. (American Society of Plastic Surgeons)
Will the head shape change right away?
Often, yes. ASPS states that open craniosynostosis procedures reposition the skull bones and that results are immediately apparent, although swelling can affect early appearance. (American Society of Plastic Surgeons)
What are the risks of open craniosynostosis surgery?
Risks can include anesthesia risks, bleeding, transfusion risks, infection, swelling, bruising, CSF leak, dura injury, incomplete correction, persistent skull gaps, scarring, need for revision surgery, and recurrence of raised intracranial pressure. ASPS lists these risks and advises families to discuss them directly with the plastic surgeon and neurosurgeon. (American Society of Plastic Surgeons)
Will the plates and screws stay in forever?
Many centers use resorbable plates and screws that dissolve over time. Seattle Children’s states that plates and screws used to hold the shape during healing dissolve completely in 1 to 2 years, though wires may rarely be used and do not dissolve. (Seattle Children's)
Will my child need another surgery later?
Many single-suture cases need one surgery. Children with multiple fused sutures, genetic syndromes, recurrent pressure, persistent skull gaps, or later growth-related issues may need more. Seattle Children’s states that babies with multiple fused sutures or genetic syndromes usually need a series of operations. (Seattle Children's)
