Medical Disclaimer This article is for educational purposes only and does not replace medical advice, diagnosis, or treatment. Incision care instructions vary by surgeon, hospital, surgery type, closure method, dressing, drain, helmet plan, and your child’s healing. Always follow the specific instructions from your child’s craniofacial surgeon, pediatric neurosurgeon, plastic surgeon, nurses, pediatrician, orthotist, and healthcare team.
After craniosynostosis surgery, parents often focus on swelling, feeding, pain, and hospital discharge.
Then, once the first shock of surgery passes, a new set of questions appears:
- How do we clean the incision?
- When can we wash the hair?
- Are the stitches dissolvable?
- Is scabbing normal?
- Should we use ointment?
- What if my baby scratches the incision?
- What will the scar look like?
- Will hair grow back over the scar?
- Will the scar be obvious later?
- What redness or drainage is concerning?
- Can a helmet rub the incision?
- When can we use sunscreen?
These questions are normal. The incision can feel emotionally loaded because it is the visible reminder of everything your child just went through.
The short answer is:
Incision care after craniosynostosis surgery depends on the surgery type and your surgeon’s instructions. Many scalp incisions are closed with absorbable stitches that do not need to be removed. Endoscopic surgery usually leaves a much smaller incision than open cranial vault remodeling. Open surgery often uses a longer zig-zag or wavy incision across the scalp that is designed to blend into the hair as it grows back. Parents should keep the incision clean as instructed, avoid soaking it until cleared, protect it from scratching and sun, avoid unapproved creams or oils, and call the surgical team for fever, increasing redness, swelling, drainage, bleeding, suture-line separation, clear fluid leakage, worsening pain, vomiting, unusual sleepiness, or poor feeding.
Weill Cornell explains that incision appearance after craniosynostosis surgery depends on the surgery type: endoscopic suturectomy may involve a 3 to 4 cm incision, while cranial vault reconstruction often uses a zig-zag incision from ear to ear that is designed to blend in once the child’s hair grows back. The same source notes that infant incisions often heal quickly and scars are usually minimal and covered by hair. (Weill Cornell Brain and Spine Center)
The key message for parents is:
Do not improvise incision care. Follow your surgical team’s exact instructions, because different hospitals use different dressings, ointments, washing schedules, and wound-care routines.
Quick Answer: What Will the Incision Look Like?
- The incision depends on the type of craniosynostosis surgery.
- Surgery type
- Common incision pattern
- Parent-friendly scar expectation
- Endoscopic strip craniectomy / suturectomy
- Usually one or more small incisions near the fused suture
- Shorter scar, often hidden by hair
- Open cranial vault remodeling
- Longer wavy or zig-zag incision across the top of the scalp
- Longer scar, designed to blend into hair
- Fronto-orbital advancement
- Usually an open scalp incision to access forehead and upper eye sockets
- Longer scalp scar, usually hidden by hair over time
- Posterior vault surgery
- Open incision across scalp, depending on approach
- Longer scalp scar, usually planned within hair-bearing scalp
- Spring-assisted surgery
- Smaller or limited incisions, depending on technique
- Scar location depends on suture and device placement
- Distraction osteogenesis
- Open or device-related incisions, sometimes with visible activation arms
- Incision and device-site care are both important
The American Society of Plastic Surgeons states that craniosynostosis incisions vary by surgeon and procedure but often extend over the top of the head from ear to ear; the incision may be wavy or zig-zag to help hide the scar within the hair. ASPS also notes that a strip of hair may be shaved near the incision, or sometimes the whole head may be shaved depending on surgeon and parent preference. (American Society of Plastic Surgeons)
The parent-friendly takeaway:
A longer incision does not mean something went wrong. Open surgery needs a larger incision so the skull bones can be reshaped directly.
Why Are Some Incisions Zig-Zag or Wavy?
Parents may expect a straight scar, then see a zig-zag or wavy incision.
That shape is intentional.
A zig-zag or wavy scalp incision can help the scar blend into the hair more naturally as the child grows. A straight line can sometimes be easier to see when hair parts along it. A zig-zag or curved pattern may make the scar less noticeable.
Texas Children’s describes open cranial vault reconstruction as starting with a zig-zag incision over the top of the baby’s head, also called a coronal incision, so the surgeons can see and reshape the skull directly. (Texas Children’s) Weill Cornell similarly notes that cranial vault reconstruction uses a zig-zag incision from ear to ear designed to blend in once the child’s hair grows back over the incision line. (Weill Cornell Brain and Spine Center)
The practical message:
The incision shape is usually planned with future scar visibility in mind.
Endoscopic Scar vs Open Surgery Scar
The biggest difference is usually size.
Endoscopic surgery scar
Endoscopic strip craniectomy or endoscopic suturectomy usually uses smaller incisions. Weill Cornell describes endoscopic suturectomy as involving a 3 to 4 cm incision, about an inch and a half, over the affected suture. (Weill Cornell Brain and Spine Center)
Open surgery scar
Open cranial vault remodeling usually uses a longer incision across the scalp. Johns Hopkins describes cranial vault remodeling as involving an incision along the baby’s scalp from ear to ear to reveal the skull. (Hopkins Medicine) Weill Cornell describes open cranial vault reconstruction as using a zig-zag incision from ear to ear, designed to blend in after hair regrowth. (Weill Cornell Brain and Spine Center)
The patient-friendly takeaway:
Endoscopic surgery usually leaves smaller scars but often requires helmet therapy afterward. Open surgery leaves a longer scalp scar but usually reshapes the skull directly and often does not require helmet therapy afterward.
Are the Stitches Dissolvable?
Often, yes.
Many craniosynostosis scalp incisions are closed with absorbable sutures. These are stitches that dissolve or fall out over time and usually do not need to be removed.
ASPS states that scalp incisions are closed with absorbable sutures and do not need to be removed. (American Society of Plastic Surgeons) Weill Cornell also states that incisions are closed with dissolvable stitches for both endoscopic and cranial vault reconstruction procedures. (Weill Cornell Brain and Spine Center) The University of Rochester notes that absorbable sutures may fall out over the next several weeks. (University of Rochester Medicine)
The practical message:
Do not pull at loose stitches unless your team specifically tells you to. Ask what dissolving stitches should look like as they fall out.
Will There Be a Head Wrap or Dressing?
Maybe.
Some children leave the operating room with a head wrap or dressing. Others may have ointment over the incision, a drain, or no large dressing depending on the procedure and hospital.
ASPS states that a head wrap may be placed at the time of surgery and is typically removed in the first 1 to 2 days after surgery; a surgical drain, if used, is typically removed in the first 2 to 3 days. (American Society of Plastic Surgeons) McGovern Medical School gives one example of discharge instructions where a dressing may be removed two days after surgery if the child is discharged with one. (McGovern Medical School)
The parent-friendly takeaway:
Ask before discharge: “Is there a dressing? When do we remove it? What should the incision look like underneath?”
What If There Was a Drain?
Some children have a drain after surgery to reduce fluid buildup under the scalp.
The University of Rochester describes a small plastic drain behind one ear that helps prevent fluid from accumulating under the skin and is typically removed a day or two after surgery before discharge. (University of Rochester Medicine) ASPS similarly notes that a surgical drain may be removed in the first 2 to 3 days after surgery. (American Society of Plastic Surgeons)
If your child had a drain, ask:
- Where was the drain?
- Is the drain site covered?
- How long should drainage continue?
- What color drainage is expected?
- When should drainage stop?
- What drainage should make us call?
The University of Mississippi Medical Center states that a drain-removal site may be covered with gauze for two days and that a small amount of clear, red, or brown drainage may be normal for the first couple of days, but drainage should stop after that. (University of Mississippi Medical Center)
The practical message:
- A drain site is separate from the incision line. Make sure you understand how to care for both.
- Incision Care at Home
The Most Important Rule: Follow Your Team’s Instructions
Incision-care instructions vary.
Some teams recommend mild soap and water.Some recommend antibiotic ointment for a set number of days.Some recommend Vaseline after antibiotic ointment.Some recommend hydrogen peroxide in a diluted form.Some advise avoiding washing directly over the incision until cleared.Some want daily shampooing but no scrubbing.
This variation can feel confusing, but it happens because surgeons use different closure techniques, dressings, and protocols.
For example, the University of Rochester instructs families to begin washing the scalp after 48 hours with a moist washcloth, mild soap, and water, then use antibiotic ointment for the first week and switch to plain Vaseline until the sutures fall off. (University of Rochester Medicine) UMass Memorial advises washing the incision with mild soap and water, patting it dry, avoiding oils, lotions, or creams unless instructed, and not soaking the incision. (UMass Memorial Health) McGovern Medical School gives a different example, advising half-strength hydrogen peroxide and antibiotic ointment after the dressing is removed, while avoiding direct washing over the incision until the doctors clear it. (McGovern Medical School)
The parent-friendly takeaway:
There is no single universal incision-care routine. Your child’s surgeon’s instructions are the source of truth.
When Can We Wash the Hair?
This depends on your hospital’s instructions.
Some teams allow gentle scalp washing within a couple of days. The University of Rochester advises beginning scalp washing after 48 hours with a moist washcloth, mild soap, and water. (University of Rochester Medicine) Weill Cornell’s FAQ says to start washing hair on the third day after surgery and shampoo daily afterward with unscented baby shampoo, while not washing directly on or scrubbing the incision line. (Weill Cornell Brain and Spine Center) The University of Mississippi Medical Center advises cleaning around the scalp incision with baby shampoo, not scrubbing the area, letting soap and water run over the incision, and avoiding submerging the head. (University of Mississippi Medical Center)
Ask your team:
- When can we wash hair?
- Can water run over the incision?
- Can shampoo touch the incision?
- Should we use baby shampoo?
- Should we avoid fragrance?
- Should we scrub or only pat?
- When can the head be submerged?
The practical message:
Hair washing is usually gentle, not vigorous. “Clean” does not mean scrubbing.
Should We Remove Scabs?
This is a common source of parent anxiety.
Scabs may form along the incision as it heals. Some teams want gentle cleaning so scabs do not build up. Other teams may strongly discourage picking or pulling at scabs.
The University of Rochester instructs families to remove developing scabs with a washcloth as part of gentle scalp cleaning after 48 hours. (University of Rochester Medicine) UMass Memorial emphasizes preventing the baby from picking, scratching, or pulling at the incision area. (UMass Memorial Health)
These instructions are not truly contradictory; the difference is gentle cleaning as directed versus picking or pulling.
The parent-friendly takeaway:
Do not pick at scabs with fingernails. Ask whether your team wants scabs gently softened and removed with washing or left alone.
Should We Use Ointment?
Maybe.
Ointment instructions vary.
Some surgeons prescribe antibiotic ointment for a certain number of days. Others may recommend petroleum jelly or no ointment after a specific point.
The University of Rochester recommends antibiotic ointment for the first week, then plain Vaseline until sutures fall off. (University of Rochester Medicine) ASPS states that antibiotic ointment is typically applied to the scalp incision line for 7 to 10 days, after which the incision line can be kept clean with soap and water. (American Society of Plastic Surgeons) The University of Mississippi Medical Center instructs families to apply bacitracin ointment to the scalp incision twice daily for 10 days after the initial dressing is removed and says ointment is no longer needed after 10 days in that protocol. (University of Mississippi Medical Center)
The practical message:
Use ointment only as instructed. More ointment, stronger ointment, or longer ointment is not automatically better.
Should We Use Hydrogen Peroxide?
Only if your team tells you to.
Hydrogen peroxide can be part of some hospital instructions, but other teams avoid it or use different cleaning plans.
McGovern Medical School gives one example of a protocol using half-strength hydrogen peroxide twice daily after dressing removal, plus antibiotic ointment. (McGovern Medical School) Other sources describe mild soap and water rather than peroxide. UMass Memorial advises washing with mild soap and water and avoiding oils, lotions, or creams unless instructed. (UMass Memorial Health)
The patient-friendly takeaway:
Do not add peroxide to the incision-care routine unless your child’s surgical team specifically instructed it.
What Should We Avoid Putting on the Incision?
Unless your team gives specific instructions, avoid:
Oils
Lotions
Creams
Scar gels
Silicone sheets
Sunscreen directly on an open or healing incision
Hair products
Fragranced shampoo
Essential oils
Powders
Unapproved antibiotic ointments
Home remedies
UMass Memorial specifically advises not using oils, lotions, or creams on the incision unless told to do so because these can weaken sutures and cause the wound to open. (UMass Memorial Health) The American Academy of Dermatology advises following the doctor’s instructions for wounds that require stitches and using sunscreen only after the wound has healed. (American Academy of Dermatology)
The practical message:
Until the incision is fully healed and your team clears scar care, treat it as a surgical wound, not a scar-treatment project.
Can the Incision Get Wet?
It depends on the stage of healing and your team’s instructions.
Many teams allow gentle washing but do not allow soaking.
UMass Memorial advises washing the incision with mild soap and water, patting it dry, and not soaking the incision in water. (UMass Memorial Health) The University of Mississippi Medical Center similarly says it is OK to let soap and water run over the incision but not to submerge the child’s head under water. (University of Mississippi Medical Center)
Ask:
- Can water run over the incision?
- Can shampoo run over it?
- Can we use a washcloth?
- When can my baby take a bath?
- When can the head be submerged?
- When is swimming allowed?
The parent-friendly takeaway:
Wet from gentle washing may be allowed before soaking or swimming is allowed. Ask for the exact difference.
How Do We Dry the Incision?
Usually, incision drying should be gentle.
Many teams recommend patting dry rather than rubbing. UMass Memorial specifically advises patting the incision dry with a soft towel after washing. (UMass Memorial Health) The University of Mississippi Medical Center advises wiping gently and patting dry rather than scrubbing. (University of Mississippi Medical Center)
The practical message:
Do not rub the incision dry. Pat gently.
What If My Baby Scratches the Incision?
Babies may rub, scratch, or pull at the incision because healing skin can feel tight or itchy.
Ways to help may include:
- Keeping nails trimmed
- Using mittens or socks on hands if approved
- Using clothing that limits scratching
- Redirecting hands
- Watching during sleep and feeding
- Keeping the incision clean as instructed
- Calling if scratching opens the skin
UMass Memorial advises preventing the baby from picking, scratching, or pulling at the incision area and suggests mittens or socks on the baby’s hands if needed. (UMass Memorial Health)
The patient-friendly takeaway:
- Itching can be part of healing, but scratching can open the incision. Protect the incision early.
- What Is Normal While the Incision Heals?
Normal Healing Changes May Include
Depending on your child’s surgery and instructions, parents may notice:
Mild pinkness along the incision
Mild swelling
Small scabs
Dissolving stitches
Tiny stitch ends
Mild crusting
Bruising nearby
Itching as healing progresses
Hair around the incision looking uneven
A scar that looks red or pink at first
Some tenderness
A drain site with small early drainage if a drain was used
The University of Rochester notes that absorbable sutures may fall out over several weeks and that the incision should be kept clean. (University of Rochester Medicine) The University of Mississippi Medical Center states that small clear, red, or brown drainage from a drain-removal site can be normal for the first couple of days, but drainage should stop after that. (University of Mississippi Medical Center)
The practical message:
Normal healing should generally trend toward less swelling, less redness, less drainage, and better comfort over time.
What Is Not Normal?
Call your child’s surgical team if you notice:
Increasing redness
Increasing swelling
Warmth around the incision
Pus
Bad-smelling drainage
Bleeding that does not stop as instructed
Suture-line separation
Skin opening
Fever
Pain that does not improve with medicine
Vomiting or not drinking
Unusual sleepiness
Seizure-like activity
Large fluid collection under the skin
Clear watery leakage from the incision
URMC advises calling if the child has redness, increased swelling, drainage, bleeding from the scalp incision, suture-line separation, fever higher than 101.5°F under the arm, pain that does not improve after medicine, not drinking liquids, or vomiting. (University of Rochester Medicine) UMass Memorial advises urgent medical contact for fever, incision separation, drainage, redness, warmth or swelling, large fluid collection under the skin, unusual drowsiness, weakness, visual disturbance, seizures, or vomiting. (UMass Memorial Health) McGovern Medical School also lists fever, a red/swollen/warm/more painful incision, pus or drainage, vomiting, increased fussiness, increased sleepiness, and seizure as reasons to call. (McGovern Medical School)
The parent-friendly takeaway:
Redness that is spreading, drainage that looks infected, skin opening, fever, vomiting, unusual sleepiness, or clear fluid leakage should not be watched silently. Call the team.
What About Clear Fluid Leakage?
Clear watery fluid from the incision should be reported promptly.
It may be harmless drainage in some situations, but after skull surgery, clear fluid can raise concern for cerebrospinal fluid, or CSF, leakage depending on the context. Parents should not try to diagnose this at home.
Johns Hopkins lists cerebrospinal fluid leak as a possible complication after craniosynostosis surgery and notes that the care team watches for symptoms such as incision redness/swelling, fever, vomiting, irritability, and decreased alertness during recovery. (Hopkins Medicine)
The practical message:
If you see clear watery drainage from the incision, call your surgical team and describe exactly what you see.
Scars After Craniosynostosis Surgery
Will the Scar Be Visible?
It may be visible at first, especially when hair is short, damp, shaved, or parted.
Over time, many craniosynostosis scars become much less noticeable because:
- Infant skin often heals quickly
- Hair grows back over the incision
- Open incisions are often zig-zag or wavy
- Incisions are usually planned within hair-bearing scalp
- The scar fades as it matures
Weill Cornell notes that incisions heal very quickly in infants, scars are usually minimal and covered by hair, and open zig-zag incisions are designed to blend in once the child’s hair grows back over the incision line. (Weill Cornell Brain and Spine Center) ASPS states that craniosynostosis incisions are typically designed as wavy or zig-zag lines to help hide the scar within the hair, and that limited-incision approaches still place incisions in hair-bearing scalp to make scars less noticeable after surgery. (American Society of Plastic Surgeons)
The parent-friendly takeaway:
The scar may look dramatic early, but many scalp scars become hard to see once hair grows back.
How Long Does Scar Healing Take?
The incision may close and look better within weeks, but scar maturation takes much longer.
A scar can continue changing in color, thickness, flatness, and softness for months to years. The American Academy of Dermatology explains that scars are a natural part of healing after surgery or injury and that most scars fade over time. (American Academy of Dermatology)
The practical message:
Do not judge the final scar during the first month. Early scars often look redder, thicker, or more obvious than they will later.
What Can Make a Scar More Noticeable?
Scar appearance can be affected by:
Infection
Wound separation
Tension on the incision
Scratching or picking
Sun exposure after healing
Individual healing tendency
Skin type
Suture reaction
Repeated surgeries
Helmet rubbing
Device-site irritation
The American Academy of Dermatology notes that scar appearance often depends on how well the wound heals and that proper wound care can help minimize the appearance of scars. It recommends keeping wounds clean, following stitch-care instructions, and applying sunscreen after the wound has healed. (American Academy of Dermatology)
The parent-friendly takeaway:
The best scar care early is good wound care: keep it clean as directed, protect it from trauma, avoid infection, and call early if something looks wrong.
Should We Use Scar Creams, Silicone, or Massage?
Not right away unless your surgeon says so.
Scar creams, silicone gel, silicone sheets, and massage are usually considered only after the incision is fully healed and the surgical team clears them. A scalp incision in a baby may also be hard to treat with silicone sheets because hair and helmets can interfere.
The American Academy of Dermatology says that if a wound requires stitches, families should follow the doctor’s advice on wound care and when stitches are removed, and that silicone gel or hydrogel sheets should be used according to instructions when appropriate. (American Academy of Dermatology) UMass Memorial advises avoiding oils, lotions, or creams on the incision unless the healthcare provider says to use them. (UMass Memorial Health)
Ask:
- Is the incision fully healed?
- Do you recommend scar massage?
- Do you recommend silicone gel or sheets?
- Will hair interfere?
- Will helmet therapy interfere?
- When can we start scar care?
- What should we avoid?
The practical message:
Do not start scar treatments while the incision is still healing. Ask first.
Sun Protection for the Scar
Sun protection matters once the wound is healed.
Sun exposure can make scars darker, redder, or more noticeable. This is especially important when hair is short or if the scar is exposed.
UMass Memorial advises protecting the incision from the sun for at least 6 months after sutures are removed, using a hat, scarf, or sunblock. (UMass Memorial Health) The American Academy of Dermatology recommends applying sunscreen to a wound after it has healed and using broad-spectrum SPF 30 or higher to reduce red or brown discoloration and help scars fade faster. (American Academy of Dermatology)
For babies, ask your pediatrician and surgeon what sun protection is safest for your child’s age. Hats, shade, and avoiding direct sun may be preferred early in infancy.
The parent-friendly takeaway:
Once the incision is healed and your team clears it, protect the scar from sun so it does not darken or stay red longer.
Hair After Craniosynostosis Surgery
Will My Baby’s Hair Be Shaved?
Maybe.
Hair-shaving practices vary by center, surgeon, surgery type, and family preference.
ASPS states that a strip of hair may be shaved in the area of the incision, or the entire head may be shaved depending on parent and surgeon preference. ASPS also notes that incisions are typically placed in hair-bearing scalp to make scars less noticeable after surgery. (American Society of Plastic Surgeons)
Ask before surgery:
- Will any hair be shaved?
- Will only a strip be shaved?
- Will the whole head be shaved?
- Can we save the hair?
- Where will the incision be compared with the shaved area?
The practical message:
Do not assume your baby’s whole head will be shaved. Ask your team exactly what they do.
Will Hair Grow Back Over the Scar?
In many children, yes, hair grows back around and over the incision enough that the scar becomes much less noticeable.
Weill Cornell states that cranial vault reconstruction incisions are designed to blend in once hair grows back over the incision line, and that scars are usually minimal and covered by hair. (Weill Cornell Brain and Spine Center) Weill Cornell’s FAQ also notes that both endoscopic and open incisions are designed to blend in once hair grows back. (Weill Cornell Brain and Spine Center)
The parent-friendly takeaway:
Hair often hides the scar very well, especially as the child grows.
What If Hair Looks Uneven at First?
That can happen.
Hair may look uneven because:
- A strip was shaved
- Hair was clipped around the incision
- Hair is matted from ointment
- The incision area is healing
- Scabs or ointment affect how hair lies
- The scar line changes how hair parts
- Baby hair grows at different rates
Parents should not judge the final appearance while the incision is still healing or while hair is still growing back.
The practical message:
The early hair pattern can look odd for a while. It usually takes time for hair growth, scar fading, and scalp healing to settle.
Can We Brush or Comb the Hair?
Ask your team.
In general, parents should avoid pulling, scraping, or brushing directly over a healing incision until cleared.
Ask:
- Can we brush around the incision?
- Can we use a soft baby brush?
- Can we comb out ointment?
- What if hair is stuck to scabs?
- What if shampoo does not remove ointment?
- Can we trim hair near the incision?
The practical message:
If hair is stuck to scabs or ointment, do not pull. Soften gently according to your team’s washing instructions.
Can We Cut the Hair After Surgery?
Ask your surgeon before cutting hair near the incision.
It may be fine after healing, but avoid clippers, scissors, or razors near a healing incision unless your team clears it. Haircuts too early may irritate the incision or introduce bacteria.
The parent-friendly takeaway:
- Wait until the incision is fully healed and the team says haircutting is safe.
- Helmet Therapy and the Incision
Can a Helmet Rub the Incision?
It should not.
If your baby had endoscopic surgery and needs a helmet, the helmet should be fitted carefully around the incision and healing scalp. Helmet therapy should be coordinated with the craniofacial team and orthotist.
ASPS notes that strip craniectomy relies on a custom helmet after surgery to improve head shape over time. (American Society of Plastic Surgeons) UMass Memorial advises that if a helmet is prescribed, families should follow the surgeon’s instructions on when and how long it should be worn, and that a helmet is not advised unless prescribed by the surgeon. (UMass Memorial Health)
Call the orthotist or surgical team if:
- The helmet rubs the incision
- There is redness that does not fade
- There are blisters
- The incision opens
- The helmet causes drainage
- The helmet slides over the incision
- The baby seems in pain when helmet is worn
The practical message:
Helmet fit is part of incision safety. A helmet should guide skull growth, not irritate the surgical wound.
When Does Helmet Therapy Start After Endoscopic Surgery?
Helmet timing varies.
Some teams begin helmet planning within the first couple of weeks after endoscopic surgery. Parents should make sure the incision is checked and the helmet plan is coordinated with swelling and healing.
McGovern Medical School gives one example where the molding helmet appointment can be scheduled after the first post-op visit or no later than two weeks after surgery. (McGovern Medical School) ASPS states that strip craniectomy relies on custom helmet use after surgery to improve head shape over time. (American Society of Plastic Surgeons)
Ask:
- When is the helmet scan?
- Does the incision need to be checked first?
- Can swelling affect fit?
- What redness is acceptable?
- Who do we call for helmet/incision concerns?
The parent-friendly takeaway:
- Helmet therapy and incision healing overlap. The surgeon and orthotist should be communicating.
- Device Sites: Springs and Distraction
If your child had spring-assisted surgery or distraction osteogenesis, incision care may include device-site care.
Parents may need to manage:
- Pin sites
- Activation arms
- Device-site cleaning
- Scalp incision care
- Drain site care
- Monitoring for redness or drainage
- Follow-up imaging
- Device removal surgery planning
The University of Mississippi Medical Center gives specific cranial distraction instructions in one protocol, including cleaning pin sites with hydrogen peroxide and Xeroform, cleaning around the scalp incision daily with baby shampoo, not scrubbing, letting soap and water run over the incision, and avoiding submerging the head. It also states distraction surgery may require weekly follow-up with X-rays. (University of Mississippi Medical Center)
The practical message:
Device-site care is different from standard incision care. Ask for written instructions and after-hours contact information.
Questions to Ask Before Leaving the Hospital
Ask:
- Where exactly is the incision?
- Are the stitches dissolvable?
- Is there glue, ointment, or dressing?
- Is there a drain site?
- When can we remove the dressing?
- When can we wash hair?
- What shampoo should we use?
- Can water run over the incision?
- Can we wash directly over the incision?
- Should we use ointment?
- Which ointment and for how long?
- Should we use Vaseline?
- Should we use hydrogen peroxide?
- Should scabs be gently removed or left alone?
- When can the head be submerged?
- When can my baby swim?
- How do we prevent scratching?
- What redness is normal?
- What drainage is normal?
- What drainage should make us call?
- What fever should make us call?
- Will the hair be shaved more later?
- When will hair grow back?
- When can we use sunscreen?
- When can we start scar care?
- Does helmet therapy affect the incision?
- Who do we call after hours?
ASPS specifically recommends asking about drains, bathing, symptoms to monitor, helmet needs, follow-up timing, and additional procedures during the recovery discussion. (American Society of Plastic Surgeons)
Red Flags: When to Call the Surgical Team
Call your child’s craniofacial or neurosurgery team promptly if you notice:
Fever
Increasing redness around the incision
Warmth around the incision
Worsening swelling at the incision
Pus or bad-smelling drainage
Drainage that increases instead of decreases
Bleeding that does not stop as instructed
Clear watery fluid leakage
Suture-line separation
Skin opening
Large fluid collection under the skin
Pain not controlled by medicine
Baby not drinking
Vomiting
Fewer wet diapers
Unusual sleepiness
Increased fussiness that feels different
Seizure-like activity
Weakness or unusual movement
Helmet rubbing, blistering, or opening the incision
Device-site redness, drainage, loosening, or turning problems if springs or distractors were used
URMC advises calling for redness, increased swelling, drainage, bleeding, suture-line separation, fever, pain not improving, not drinking, or vomiting. (University of Rochester Medicine) UMass Memorial advises immediate care for fever, incision separation, drainage, redness, warmth, swelling, large fluid collection, unusual drowsiness, weakness, visual disturbance, seizures, or vomiting. (UMass Memorial Health) McGovern Medical School also lists fever, incision redness/swelling/warmth/pain, pus or drainage, vomiting, increased fussiness, increased sleepiness, and seizure as reasons to call. (McGovern Medical School)
Seek urgent or emergency care if your child is difficult to wake, has trouble breathing, has repeated vomiting, has seizure-like activity, has clear fluid leakage, has a rapidly enlarging fluid collection, or seems seriously ill.
Common Parent Fears
“The incision looks huge. Is that normal?”
It can be, especially after open cranial vault surgery. Open surgery often uses a longer incision across the scalp so the surgeons can reshape the skull directly. Johns Hopkins describes open cranial vault remodeling as using an incision along the scalp from ear to ear, while Weill Cornell describes cranial vault reconstruction as using a zig-zag incision from ear to ear. (Hopkins Medicine)
“Will the scar be visible forever?”
The scar may be visible at first, but many scalp scars become much less noticeable as hair grows back. Weill Cornell states that infant incisions heal quickly, scars are usually minimal and covered by hair, and open incisions are designed to blend in after hair regrowth. (Weill Cornell Brain and Spine Center)
“Will hair grow over the scar?”
Often, yes. Weill Cornell notes that cranial vault reconstruction incisions are designed to blend once hair grows back over the incision line. (Weill Cornell Brain and Spine Center)
“Can I wash my baby’s hair?”
Usually yes at some point, but timing and method vary. Weill Cornell says to start washing on the third day after surgery with unscented baby shampoo and not scrub the incision line, while the University of Rochester says to begin gentle scalp washing after 48 hours. Follow your team’s instructions. (Weill Cornell Brain and Spine Center)
“Should I put scar cream on the incision?”
Not unless your team says so. UMass Memorial warns against oils, lotions, or creams on the incision unless the healthcare provider instructs it, because they can weaken sutures and cause wound opening. (UMass Memorial Health)
“Can I use sunscreen on the scar?”
Only after the wound has healed and your child’s team says it is safe. The American Academy of Dermatology recommends sunscreen after a wound has healed to help reduce discoloration and help scars fade, while UMass Memorial advises protecting the incision from sun for at least 6 months after sutures are removed. (American Academy of Dermatology)
“What if my baby scratches the incision?”
Try to prevent scratching with trimmed nails, mittens or socks if approved, and close supervision. UMass Memorial specifically recommends preventing babies from picking, scratching, or pulling at the incision area. (UMass Memorial Health)
How to Explain the Incision and Scar to Family
Here is a simple explanation:
“The incision depends on the type of craniosynostosis surgery. Endoscopic surgery usually has a small incision, while open cranial vault surgery often has a longer zig-zag or wavy incision across the scalp so the surgeons can reshape the skull. The scar may look obvious at first, especially while the hair is shaved or short, but the incision is usually planned in the hair-bearing scalp so hair can help hide it as it grows back. Right now, the most important thing is keeping the incision clean as instructed, protecting it from scratching, avoiding unapproved creams or oils, and calling the team for fever, redness, drainage, swelling, bleeding, skin opening, clear fluid leakage, vomiting, or unusual sleepiness.”
This can help relatives understand why the incision may look intense early but still heal well over time.
Incision care after craniosynostosis surgery depends on the surgery type and your surgeon’s protocol.
Endoscopic surgery usually leaves a smaller incision than open cranial vault remodeling.
Open surgery often uses a longer wavy or zig-zag incision across the scalp, commonly from ear to ear.
Zig-zag or wavy incisions are often designed to blend into the hair.
Many craniosynostosis scalp incisions are closed with absorbable stitches that do not need to be removed.
Hair may be shaved only in a strip or sometimes over the whole head depending on surgeon and parent preference.
Hair often grows back over the incision and helps hide the scar.
Do not pull at dissolving stitches or scabs.
Wash hair only as instructed by your team.
Some teams recommend mild soap and water, some recommend baby shampoo, some recommend ointment, and some use other protocols.
Do not use oils, lotions, creams, scar gels, sunscreen, or home remedies on a healing incision unless your team says to.
Do not soak the incision until cleared.
Protect the incision from scratching, picking, rubbing, and helmet pressure.
Once healed and cleared, sun protection can help reduce scar discoloration.
Call the surgical team for fever, increasing redness, warmth, swelling, drainage, bleeding, skin opening, suture-line separation, clear fluid leakage, vomiting, poor feeding, unusual sleepiness, seizure-like activity, or helmet/device irritation.
The simplest parent-friendly summary is:
The incision may look dramatic at first, especially after open surgery, but many craniosynostosis scars heal well and become hidden by hair. Early care matters: keep it clean as instructed, avoid unapproved products, protect it from scratching and sun, and call the team early if anything looks infected, open, leaking, or worsening.
Frequently Asked Questions About Incision Care, Scars, and Hair After Craniosynostosis Surgery
What will the scar look like after craniosynostosis surgery?
It depends on the surgery type. Endoscopic suturectomy may leave a 3 to 4 cm incision, while cranial vault reconstruction often leaves a zig-zag incision from ear to ear. Weill Cornell states that these incisions are designed to blend in once the child’s hair grows back. (Weill Cornell Brain and Spine Center)
Why is the open surgery incision so long?
Open cranial vault remodeling uses a longer incision so surgeons can directly access, release, reshape, and secure skull bones. Johns Hopkins describes cranial vault remodeling as involving an incision along the scalp from ear to ear to reveal the skull. (Hopkins Medicine)
Why is the incision zig-zag or wavy?
The incision may be designed that way to help hide the scar within the hair. ASPS states that craniosynostosis incisions may be wavy or zig-zag to help hide the scar within the hair. (American Society of Plastic Surgeons)
Are the stitches dissolvable?
Often, yes. ASPS states that scalp incisions are closed with absorbable sutures that do not need to be removed. (American Society of Plastic Surgeons)
When do dissolvable stitches fall out?
Timing varies. The University of Rochester states that absorbable sutures may fall out over the next several weeks. (University of Rochester Medicine)
When can I wash my baby’s hair after craniosynostosis surgery?
Timing varies by surgeon. The University of Rochester advises gentle scalp washing after 48 hours, while Weill Cornell says to start washing hair on the third day after surgery and use unscented baby shampoo without scrubbing the incision line. Follow your team’s instructions. (University of Rochester Medicine)
Can shampoo touch the incision?
Ask your team. Some instructions allow soap and water to run over the incision but advise no scrubbing or submerging. The University of Mississippi Medical Center says soap and water may run over the incision, but the area should not be scrubbed or submerged. (University of Mississippi Medical Center)
Should I use antibiotic ointment?
Only if your team instructs it. ASPS states that antibiotic ointment is typically applied for 7 to 10 days before the incision is kept clean with soap and water, but protocols vary. (American Society of Plastic Surgeons)
Should I use Vaseline?
Only if instructed. The University of Rochester gives one example protocol using antibiotic ointment for the first week and then plain Vaseline until the sutures fall off. (University of Rochester Medicine)
Should I use hydrogen peroxide?
Only if your team specifically instructs it. McGovern Medical School includes half-strength hydrogen peroxide in one discharge protocol, but other hospitals use mild soap and water instead. (McGovern Medical School)
Should I pick scabs off the incision?
No. Do not pick with fingernails or pull at scabs. Some teams instruct gentle scab removal with washing, while others emphasize avoiding scratching or picking. Ask your team what they want for your child. (University of Rochester Medicine)
Can the incision be submerged in bath water?
Usually not until cleared. UMass Memorial advises not soaking the incision in water, and the University of Mississippi Medical Center says not to submerge the child’s head under water after certain procedures. (UMass Memorial Health)
Can my baby swim after craniosynostosis surgery?
Ask your team. Some discharge instructions restrict swimming for several weeks. The University of Mississippi Medical Center lists no swimming for three weeks in its post-op instructions. (University of Mississippi Medical Center)
Can I put lotion, oil, or cream on the incision?
Not unless your team says so. UMass Memorial warns that oils, lotions, or creams can weaken sutures and cause wound opening if used without approval. (UMass Memorial Health)
When can we start scar care?
Ask your surgeon. Scar treatments such as massage, silicone, or scar gel should generally wait until the incision is fully healed and the team clears it. The American Academy of Dermatology advises following the doctor’s wound-care instructions for stitched wounds. (American Academy of Dermatology)
Will the scar fade?
Most scars fade over time, although they may not disappear completely. The American Academy of Dermatology states that scars are a natural part of healing and that most scars fade over time. (American Academy of Dermatology)
Should the scar be protected from sun?
Yes, once the wound is healed and your team clears sun protection. UMass Memorial advises protecting the incision from sun for at least 6 months after sutures are removed, and the American Academy of Dermatology recommends broad-spectrum SPF 30 or higher after a wound has healed to help reduce discoloration. (UMass Memorial Health)
Will my baby’s hair be shaved?
Maybe. ASPS states that a strip of hair may be shaved near the incision or the entire head may be shaved depending on surgeon and parent preference. (American Society of Plastic Surgeons)
Will hair grow back over the incision?
Often, yes. Weill Cornell states that open surgery incisions are designed to blend in once hair grows back over the incision line. (Weill Cornell Brain and Spine Center)
What if the helmet rubs the incision?
Call the orthotist and surgical team. A helmet should not rub, blister, open, or irritate the incision. UMass Memorial advises following the surgeon’s helmet instructions when a helmet is prescribed. (UMass Memorial Health)
What incision symptoms should make me call the doctor?
Call for increasing redness, swelling, warmth, pain, drainage, pus, bleeding, suture-line separation, fever, vomiting, not drinking, unusual sleepiness, or seizure-like activity. URMC, UMass Memorial, and McGovern Medical School all list these types of symptoms as reasons to call after craniosynostosis surgery. (University of Rochester Medicine)
What if the incision leaks clear fluid?
Call the surgical team promptly. Clear watery fluid can raise concern for CSF leak depending on the situation. Johns Hopkins lists CSF leak as a possible complication after craniosynostosis surgery. (Hopkins Medicine)
