Craniosynostosis Surgery Day

Medical Disclaimer This article is for educational purposes only and does not replace medical advice, diagnosis, or treatment. Surgery-day instructions vary by hospital, child, procedure, anesthesia plan, blood-management plan, and craniofacial team. Always follow the instructions from your child’s pediatric neurosurgeon, craniofacial plastic surgeon, anesthesiologist, pediatrician, ICU team, and hospital staff.

Craniosynostosis surgery day can feel like the longest day of a parent’s life.

Even after weeks or months of appointments, scans, second opinions, packing lists, and pre-op instructions, many parents still wake up that morning with the same questions:

• Will my baby be safe under anesthesia?
• Will my baby need a breathing tube?
• How much blood loss is expected?
• Will there be a blood transfusion?
• How long will surgery take?
• Will we get updates?
• Where do we wait?
• Will my child go to the ICU?
• When will we see our baby again?
• What will our baby look like after surgery?
• These questions are normal.

The short answer is:

Craniosynostosis surgery day usually involves check-in, pre-op evaluation, anesthesia, surgery, recovery room or ICU transfer, and close monitoring afterward. General anesthesia is used so your child is asleep and pain-free during surgery. Blood loss and transfusion planning depend heavily on the surgery type: open cranial vault remodeling is more likely to involve transfusion, while endoscopic strip craniectomy is less likely. Parents should ask ahead of time how updates will be given, whether ICU care is expected, what blood-management plan is in place, and when they will be reunited with their child.

Mayo Clinic explains that craniosynostosis surgery is usually performed by a craniofacial surgeon and neurosurgeon, and that surgery may be endoscopic or open depending on which and how many sutures have closed. Mayo also notes that endoscopic surgery typically has smaller incisions, a shorter hospital stay, and usually does not need blood transfusion, while open surgery typically involves a 3- to 4-day hospital stay and usually does need blood transfusion. (Mayo Clinic)

Seattle Children’s provides a parent-facing comparison showing that open cranial vault surgery is longer, more likely to need a blood transfusion, and usually involves 3 to 5 hospital days including 1 ICU day, while endoscopic strip craniectomy is shorter, less likely to need transfusion, and may involve a shorter stay. (Seattle Children's)

This guide focuses on the practical and emotional details of surgery day.

Quick Answer: What Should Parents Expect on Surgery Day?

Every hospital has its own process, but craniosynostosis surgery day often includes:

Hospital check-in

Registration and ID bands

Pre-op nurse assessment

Vital signs

Review of fasting, medications, allergies, illness, and consent forms

Meeting the anesthesia team

Meeting the surgical team

Possible pre-op medication to help your child relax

Separation for the operating room

General anesthesia

IV placement, monitoring lines, and breathing support as needed

Surgery

Parent updates during surgery

Recovery room, ICU, or hospital-room transfer

Reunion with parents when the team says it is safe

Pain control, swelling monitoring, feeding plan, and overnight observation

Seattle Children’s states that families receive updates every couple of hours while a child is in the operating room, are given a pager while waiting, and meet with the surgeon in person after surgery. (Seattle Children's) Children’s National recommends reviewing surgery preparation as soon as surgery is scheduled and bringing comfort items, special feeding items, chargers, and things for parents to do while waiting. (Children's National Hospital)

The parent-friendly takeaway:

Surgery day has many steps, but you do not have to manage them alone. The hospital team moves your child through the process while you focus on being present, informed, and reachable.

Before Leaving Home

Before leaving for the hospital, confirm:

Arrival time

Hospital location

Parking plan

Check-in area

Fasting instructions

Medication instructions

Insurance and ID

Consent paperwork if needed

Comfort item

Phone charger

Any special feeding supplies

The phone number to call if something changes

Fasting instructions are especially important. HealthyChildren.org, from the American Academy of Pediatrics, explains that a child’s stomach should be empty when anesthesia starts except in emergencies; fasting helps reduce the risk of vomiting with aspiration, and surgery may be delayed or rescheduled if fasting instructions are not followed. (HealthyChildren.org)

The practical message:

Do not adjust fasting times on your own. Follow the exact instructions from your child’s hospital, surgeon, or anesthesiology team.

What If Your Child Gets Sick Before Surgery?

Call the surgical team before going to the hospital if your child develops:

Fever

Cold symptoms

Cough

Wheezing

Vomiting

Diarrhea

Rash

Fever blister

New breathing symptoms

Known contagious illness exposure

Any new illness or medication change

Children’s National advises families to call the surgeon immediately if a child has a cold, fever, rash, or fever blister because the operation may need to be postponed. (Children's National Hospital) HealthyChildren.org similarly advises notifying the anesthesia team and child’s doctor if the child becomes ill before a procedure, because some illnesses can increase anesthesia risk and postponing may be safest. (HealthyChildren.org)

The patient-friendly takeaway:

Do not hide illness because you are afraid surgery will be delayed. The anesthesia team needs the full picture to keep your child safe.

At Hospital Check-In

At check-in, expect staff to confirm:

Your child’s name and date of birth

The planned surgery

The surgical side or area, if relevant

Allergies

Last food or drink

Current medications

Recent illness

Parent or guardian identity

Insurance and paperwork

Emergency contact information

Children’s National lists photo ID, insurance card, referral or authorization if needed, guardianship documents when applicable, consent forms, and medical history/physical forms among documents families may need on surgery day. (Children's National Hospital)

The practical message:

You may be asked the same questions many times. This repetition is part of safety checking, not a sign that the team is disorganized.

In the Pre-Op Area

The pre-op area is where the team prepares your child for surgery.

A nurse may:

Check vital signs

Ask about fasting

Review allergies

Confirm medications

Confirm recent illness status

Place ID bands

Review paperwork

Explain what happens next

Ask about comfort items

Answer practical questions

The surgical team may:

• Review the operation
• Confirm the suture or procedure
• Mark anything that needs marking
• Review risks and consent
• Answer last-minute questions

The anesthesia team may:

• Review medical history
• Ask about previous anesthesia reactions
• Ask about breathing, heart, reflux, prematurity, seizures, airway, or sleep concerns
• Review fasting
• Explain anesthesia plan
• Discuss IVs, breathing tube, monitoring, pain control, and recovery

Children’s Health states that a pre-operative anesthesia assessment may happen days before surgery or on surgery day and may include medical history, physical exam, and any needed testing; it also notes that this is a time to answer questions and prevent delays on surgery day. (Children's Health)

The parent-friendly takeaway:

Pre-op is your last quiet window to ask questions before surgery starts. Bring a written list.

General Anesthesia: What It Means

Most craniosynostosis surgery is done under general anesthesia.

General anesthesia means your child is fully asleep, does not feel pain during surgery, and does not remember the operation. Children’s Health defines general anesthesia as medications that provide loss of consciousness, prevent memory formation, and eliminate pain during surgery. (Children's Health) CHOP similarly explains that general anesthesia makes a child unconscious during surgery and may be given through a breathing mask, tube, or IV. (Children's Hospital of Philadelphia)

The anesthesia team monitors your child throughout surgery, including breathing, oxygen level, heart rate, blood pressure, temperature, fluids, and pain control.

The practical message:

Anesthesia is not just “putting the child to sleep.” It is continuous medical monitoring and support from before surgery begins until your child is stable after surgery.

Will My Baby Get Anesthesia Through a Mask or IV?

This depends on your child’s age, medical condition, hospital protocol, and anesthesia plan.

Some children fall asleep with anesthesia gas through a mask, then have an IV placed after they are asleep. Other children may need an IV before going to sleep if the anesthesia team believes that is safer.

Children’s Health explains that some children receive medication in the pre-op area to relax, then may fall asleep with anesthesia air through a mask and have an IV placed after they are asleep; in older children, or when safer for younger children, the IV may be started before the operating room. (Children's Health)

The parent-friendly takeaway:

Ask the anesthesiologist, “Will my child go to sleep with a mask or an IV, and why is that safest for this surgery?”

Will My Child Need a Breathing Tube?

Often, yes.

During major surgery under general anesthesia, a breathing tube may be placed after the child is asleep to help protect the airway and support breathing during surgery.

CHOP explains that children under general anesthesia may need a breathing tube placed into the windpipe so they can breathe properly during surgery. (Children's Hospital of Philadelphia) Children’s Health explains that a breathing tube is placed after the child is asleep and passes through the mouth into the trachea. (Children's Health)

The practical message:

The breathing tube is usually placed after your child is asleep and removed before or during early recovery, unless the team believes ICU breathing support is safer for a specific reason.

Will Parents Be With the Child When Anesthesia Starts?

This varies by hospital, child age, procedure, and anesthesia team preference.

Some hospitals may allow a parent to accompany a child until they fall asleep in selected cases. Other hospitals do not allow parents into the operating room for safety, sterility, and workflow reasons.

Children’s National states that parent presence during the start of anesthesia may be allowed at the anesthesiologist’s discretion for certain non-emergency patients, with staff available to escort the parent from the operating room to the waiting area. (Children's National Hospital) Children’s Health states that parents generally do not stay in sterile operating rooms during surgery, though in some cases a parent may accompany the child into the operating room until the child falls asleep. (Children's Health)

The parent-friendly takeaway:

Ask ahead of time, but prepare emotionally for either answer. Not being allowed in the operating room does not mean your child is alone.

What Should Parents Tell the Anesthesiologist?

Tell the anesthesia team about:

Prematurity history

NICU stay

Breathing problems

Sleep apnea or snoring

Reflux or vomiting

Heart conditions

Seizures

Airway concerns

Previous anesthesia

Family history of anesthesia problems

Allergies

Latex allergy

Medication allergies

Current medicines

Recent fever, cough, cold, wheezing, vomiting, diarrhea, or rash

Blood transfusion reactions in the child or family

Children’s National recommends discussing medications, allergies to medicine, food or latex, reactions to anesthesia or blood transfusion, nausea after anesthesia, immunization record, previous illnesses, previous operations, hospital stays, tests, treatments, and anything that might put the child at risk during the hospital visit. (Children's National Hospital)

The practical message:

No detail is too small if it could affect anesthesia, airway, bleeding, medications, or recovery.

What Lines and Monitors Might Be Used?

Depending on the procedure, the anesthesia team may use:

IV line

Breathing tube

Blood pressure cuff

Oxygen monitor

Temperature monitor

Urinary catheter in some cases

Arterial line in some major surgeries

Central line in selected major surgeries

Blood tests during or after surgery

Children’s Health explains that an IV is a small catheter in a vein used to give fluids and medications; an arterial line can measure blood pressure beat-by-beat and allow blood tests during major surgery; and a central line may be placed for major surgery in selected cases. (Children's Health)

The patient-friendly takeaway:

More lines do not always mean something is wrong. In major surgery, lines may help the team monitor your child closely and respond quickly.

Blood Loss: Why It Is Discussed in Craniosynostosis Surgery

Craniosynostosis surgery involves skull bone and scalp tissue, both of which can bleed.

How much bleeding is expected depends on:

Surgery type

Child’s age and size

Suture pattern

Open vs endoscopic approach

Whether the forehead, orbit, back of skull, or entire vault is involved

Whether multiple sutures are fused

Surgery length

Blood conservation protocols

Child’s blood count before surgery

Mayo Clinic states that open craniosynostosis surgery usually needs blood transfusion, while endoscopic surgery usually does not. (Mayo Clinic) Seattle Children’s also lists open cranial vault surgery as likely to need transfusion and endoscopic strip craniectomy as less likely to need transfusion. (Seattle Children's)

The parent-friendly takeaway:

Blood loss planning is normal in craniosynostosis surgery. It is not a sign that the team expects something to go wrong.

Why Open Surgery Has More Transfusion Discussion

Open cranial vault remodeling reshapes skull bones directly. That larger exposure and more extensive bone work can increase bleeding compared with minimally invasive endoscopic procedures.

Mayo Clinic states that open surgery involves reshaping the skull, typically requires a 3- to 4-day hospital stay, and usually needs blood transfusion. (Mayo Clinic) Seattle Children’s comparison table states that open cranial vault surgery is likely to need a blood transfusion, while endoscopic strip craniectomy is less likely to need one. (Seattle Children's)

The practical message:

If your child is having open cranial vault remodeling, fronto-orbital advancement, or total vault surgery, ask about the transfusion plan before surgery day.

Why Endoscopic Surgery Has Less Transfusion Discussion

Endoscopic strip craniectomy usually uses smaller incisions and removes the fused suture without directly reshaping the entire skull. Because the operation is less extensive, blood loss is often lower than in open cranial vault remodeling.

Mayo Clinic states that endoscopic surgery has smaller incisions, usually involves only a one-night hospital stay, and usually does not need blood transfusion. (Mayo Clinic) Seattle Children’s lists endoscopic strip craniectomy as shorter and less likely to require transfusion than open cranial vault surgery. (Seattle Children's)

The balanced message:

Endoscopic surgery is less likely to require transfusion, but parents should still ask what the blood plan is, because every surgery has bleeding risk.

What Does “Type and Crossmatch” Mean?

Before surgery, your child may have blood drawn for type and crossmatch.

This means the blood bank determines your child’s blood type and prepares compatible blood in case transfusion is needed.

ASPS states that before craniosynostosis surgery, a child may be asked to get lab testing and a crossmatch for blood to be transfused. (American Society of Plastic Surgeons) Children’s Health explains that when blood loss is anticipated, blood matched to the child is kept available, and in emergencies blood can be obtained quickly from the blood bank. (Children's Health)

The parent-friendly takeaway:

Crossmatching blood does not mean your child definitely will need a transfusion. It means the team is prepared.

What Blood Conservation Questions Should Parents Ask?

Parents can ask:

• Is blood transfusion likely for this procedure?
• Will my child have blood typed and crossmatched?
• What is my child’s hemoglobin before surgery?
• Do you use blood-conservation strategies?
• Do you use tranexamic acid or other medications to reduce bleeding?
• Do you use cell saver, if appropriate for this case?
• Do you use arterial lines for close monitoring?
• Will blood tests be checked during surgery?
• What transfusion threshold do you use?
• Can parents donate directed blood?
• What happens if transfusion is needed urgently?

Children’s Health explains that when expected blood loss is known based on the surgery, the team may use tools such as arterial lines or central venous catheters to monitor closely and ensure blood can be given and blood loss replaced through functioning IV lines. (Children's Health) ASPS recommends asking whether surgery will require a blood transfusion and discussing planned hospital stay and ICU stay during the surgical consultation. (American Society of Plastic Surgeons)

The practical message:

You do not need to become a blood-management expert. You only need to understand the plan, likelihood, alternatives, and risks.

What If Parents Have Religious or Personal Concerns About Blood Transfusion?

Tell the surgical team as early as possible.

Do not wait until surgery day.

Children’s National specifically advises families with religious objections to blood transfusion to discuss this with the surgeon well in advance of surgery. (Children's National Hospital)

The parent-friendly takeaway:

Transfusion concerns should be part of early surgical planning, not a last-minute conversation in pre-op.

What Are the Risks Parents Should Understand?

Craniosynostosis surgery risks depend on the operation and child, but parents should understand the major categories.

ASPS lists possible craniosynostosis surgery risks including anesthesia risks, bleeding, infection, injury to the dura or large brain veins, cerebrospinal fluid leak, risks related to blood transfusion, swelling and bruising including temporary eye swelling, incomplete correction, persistent skull gaps, scarring, revision surgery, recurrence of raised intracranial pressure, and very rare risks such as blindness or death. (American Society of Plastic Surgeons)

The practical message:

Consent is not meant to scare parents. It is meant to make sure you understand the expected benefits, possible risks, and how complications are handled.

What Happens While Parents Are Waiting?

Waiting can feel unreal. Parents often describe the hours as slow, quiet, and emotionally intense.

Depending on the hospital, families may wait in:

• Surgery waiting room
• Family lounge
• Cafeteria area
• Private consult room
• Nearby hotel or hospital housing if surgery is long and updates are remote

Seattle Children’s states that while a child is in the operating room, families receive updates every couple of hours, are given a pager while waiting, and speak with the surgeon in person when surgery is done. (Seattle Children's)

The practical message:

Ask before surgery starts exactly how updates will happen and where you are expected to wait.

What Do Surgery Updates Mean?

Updates may sound brief and technical.

You may hear:

• “We have started anesthesia.”
• “The child is asleep and stable.”
• “The incision has started.”
• “The team is working on the skull.”
• “The reconstruction is underway.”
• “They are closing.”
• “Your child is going to recovery.”
• “The surgeon will come speak with you.”

Not every update means a major event has happened. Many updates simply mean the case is progressing normally.

The parent-friendly takeaway:

If an update is unclear, ask the messenger: “Is everything going as expected?”

Waiting Room Tips for Parents

Here are practical ways to make the waiting period more manageable.

Bring:

Phone charger

Portable charger

Water bottle

Snacks if allowed

Notebook and pen

Medication for parents if needed

Sweater or layers

Headphones

Comfort object from home if helpful

A list of people to update

Something quiet to do

Children’s National includes “something to occupy your time while you’re waiting,” such as a phone and charger, magazines, knitting, or laptop, in its surgery checklist. (Children's National Hospital)

The practical message:

You may not be able to relax, but you can reduce avoidable stress by having chargers, food, water, and a communication plan.

Decide Who Updates Family and Friends

Surgery day can become overwhelming if many people text for updates.

Before surgery, decide:

• Who will be the point person?
• Will one parent send updates?
• Will a relative update extended family?
• Will you use a group text?
• Will you wait until after surgery to update people?
• Do you want privacy until the surgeon has spoken with you?

A simple text might say:

“We checked in. Surgery has started. We will update when we hear more. Please understand if we do not answer individual messages today.”

The parent-friendly takeaway:

You are allowed to protect your attention and emotional energy on surgery day.

What to Do During the Longest Part of Waiting

Many parents cannot focus on reading or work. That is normal.

Some parents find it helps to:

Walk briefly if allowed

Eat something

Take turns stepping outside

Use breathing exercises

Pray or meditate

Text one trusted person

Write questions for the surgeon

Listen to music or a podcast

Avoid online searching during surgery

Ask the waiting-room staff how long until the next update

The practical message:

The goal is not to feel calm. The goal is to get through the waiting period without adding extra fear.

When the Surgeon Comes Out

When the surgeon comes to speak with you, you may feel too emotional to absorb everything.

Ask:

• How did surgery go?
• Was the planned surgery completed?
• Was there anything unexpected?
• How much blood loss occurred?
• Was a transfusion needed?
• Is my child stable?
• Where is my child now?
• When can we see them?
• Will they go to ICU or recovery?
• Is the breathing tube out?
• What should we expect in the first night?
• What will swelling look like?
• What are you watching most closely?
• Write down answers if you can.

The practical takeaway:

The surgeon conversation may be short and emotional. Ask the most important questions first: Is my child stable? Was the surgery completed? When can we see them?

Recovery Room, ICU, or Hospital Room: What Happens Next?

After surgery, your child may go to:

• PACU, also called recovery room
• ICU
• Hospital floor

The destination depends on the surgery type, anesthesia plan, bleeding, breathing, swelling, age, and hospital protocol.

Children’s Health explains that after major surgery or when longer monitoring is needed, a child may be admitted to the floor or ICU. It also notes that parents are usually called to the bedside in recovery once the nurse feels the child is stable, though timing varies depending on the child’s medical needs. (Children's Health) Seattle Children’s describes ICU time as part of typical hospital stay for both open and endoscopic craniosynostosis surgery pathways in its comparison table. (Seattle Children's)

The parent-friendly takeaway:

If you cannot see your child immediately, it does not automatically mean something is wrong. The team may be stabilizing, monitoring, moving lines, checking breathing, or settling your child safely.

What Will My Child Look Like After Surgery?

What you see depends on the surgery type.

After endoscopic surgery, there may be:

• Small incisions
• Some swelling
• Sleepiness
• Bandage or incision ointment
• Less facial swelling than open surgery in many cases

After open cranial vault remodeling or fronto-orbital advancement, there may be:

• Head swelling
• Face swelling
• Puffy eyelids
• Eyes partly or fully swollen shut
• Bruising
• A larger incision
• Bandages or ointment
• Drowsiness from anesthesia

ASPS lists swelling and bruising, including eyes swelling shut temporarily, among craniosynostosis surgery risks and expected recovery issues. (American Society of Plastic Surgeons)

The patient-friendly takeaway:

The first post-op appearance can be shocking even when recovery is normal. Ask your team before surgery what swelling is expected for your child’s procedure.

Feeding After Anesthesia

Feeding usually restarts gradually after the team says it is safe.

Children’s Health recommends starting with liquids first after anesthesia; once clear liquids are tolerated, breast milk or formula may be attempted, with regular food usually later depending on whether the child is admitted or going home. (Children's Health)

For babies after craniosynostosis surgery, feeding may be slower at first because of:

• Sleepiness
• Sore throat from breathing tube
• Swelling
• Pain medication
• Nausea
• General discomfort

The practical message:

Ask the recovery or ICU nurse what feeding goal your child must meet before moving rooms or going home.

Pain Control After Surgery

Pain control may include:

• IV medication
• Oral medication
• Scheduled acetaminophen
• Other medications depending on the surgeon’s instructions
• Comfort positioning
• Holding when allowed
• Reducing noise and stimulation

Children’s Health explains that the anesthesia team gives medications so the child remains asleep during surgery and comfortable when waking, and that pain-control approaches after surgery may include IV medication systems in some cases. (Children's Health)

Ask:

• What pain medication will be used?
• How often can it be given?
• What pain signs should we watch for?
• What if my baby will not feed because of pain?
• Which medicines should we avoid?
• Who manages pain overnight?

The patient-friendly takeaway:

Parents know their baby’s comfort cues. Tell the nurse if something seems off.

Will My Child Still Have a Breathing Tube After Surgery?

Most children have the breathing tube removed before leaving the operating room or early in recovery, but this depends on the child and procedure.

Children’s Health explains that once surgery is finished, anesthesia gas is turned off and the team makes sure the child is comfortable and breathing well before removing the breathing tube; in some severe situations, it may be safer to keep the breathing tube in place and recover in the ICU. (Children's Health)

The practical message:

Ask the surgeon or anesthesiologist whether your child is expected to wake up with the breathing tube out or whether ICU breathing support is possible.

The First Night

The first night is often about monitoring.

The team may watch:

Breathing

Heart rate

Blood pressure

Temperature

Pain

Swelling

Neurologic status

Urine output

Feeding

Blood counts

Incision

Drain output if a drain is used

Signs of bleeding

Signs of nausea or vomiting

Seattle Children’s states that most babies spend time in the ICU after open cranial vault reconstruction and fronto-orbital advancement, and its surgery comparison table includes ICU time in both open and endoscopic pathways. (Seattle Children's)

The parent-friendly takeaway:

The first night can include many checks and interruptions. That monitoring is part of safety after major craniofacial surgery.

Surgery Day by Procedure Type

Endoscopic Strip Craniectomy

Parents may expect:

• Shorter surgery than open surgery
• Smaller incisions
• Less transfusion likelihood
• Shorter stay
• Helmet therapy after surgery

Seattle Children’s states that endoscopic strip craniectomy uses an endoscope and small tools, involves two small incisions, removes bone without reshaping the skull, and is followed by helmet therapy for several months. (Seattle Children's) Mayo Clinic states that endoscopic surgery usually does not need transfusion and typically involves only a one-night hospital stay. (Mayo Clinic)

Ask:

• When will helmet planning start?
• When do we meet the orthotist?
• How often will follow-up happen?
• What swelling is expected?
• What would delay discharge?

Open Cranial Vault Remodeling

Parents may expect:

• Longer surgery
• Larger incision
• More swelling
• Higher transfusion likelihood
• ICU monitoring
• Several hospital days
• Usually no helmet afterward

Seattle Children’s describes open cranial vault reconstruction as involving a zig-zag incision, separation of soft tissue, dura separation, bone reshaping, possible dissolving plates and screws, 3 to 5 hospital nights including 1 ICU night, and no helmet needed after surgery. (Seattle Children's) Mayo Clinic states that open surgery usually needs blood transfusion and typically involves a 3- to 4-day hospital stay. (Mayo Clinic)

Ask:

• Was transfusion likely and planned?
• How much swelling should we expect?
• Will the eyes swell shut?
• How will pain be managed?
• When can we wash hair?

Fronto-Orbital Advancement

Parents may expect:

• Forehead and upper eye-socket reshaping
• Several hours of surgery
• ICU stay
• Eye and forehead swelling
• Possible transfusion discussion

Seattle Children’s states that fronto-orbital advancement moves and reshapes the forehead and upper eye sockets, creates more brain space and eye protection, takes 4 to 5 hours, and usually involves 3 to 4 hospital days including 1 ICU day. (Seattle Children's)

Ask:

• How will the forehead and eyes look afterward?
• What eye swelling is expected?
• Do we need ophthalmology follow-up?
• What signs would be concerning?

Spring-Assisted Surgery or Distraction

Parents may expect:

• Device placement
• Device monitoring
• Possible imaging after surgery
• Second procedure later for spring or device removal
• Device-site care instructions
• Questions about whether parents turn devices if distraction is used

Mayo Clinic notes that springs may be placed after a closed suture is removed, and another surgery is needed to remove the springs. (Mayo Clinic)

Ask:

• What device is being placed?
• Will anything be visible outside the scalp?
• Will we need to turn anything?
• When is removal planned?
• What device-site symptoms should make us call?

Ask:

• Is the planned operation still the same?
• Which suture or sutures are being treated?
• How long do you expect surgery to take?
• Will both neurosurgery and craniofacial plastic surgery be involved?
• Is blood crossmatched and available?
• Is transfusion expected?
• Will my child go to ICU?
• How often will we receive updates?
• Who will update us?
• When will we see our child?
• What should we expect immediately after surgery?

ASPS recommends discussing hospital stay, possible blood transfusion, ICU stay, surgical technique, expected recovery, risks, head-shape changes, and helmet needs during craniosynostosis surgery consultation. (American Society of Plastic Surgeons)

Ask:

• What type of anesthesia will my child receive?
• Will my child go to sleep with a mask or IV?
• Will a breathing tube be used?
• Will an arterial line be used?
• Will central access be used?
• How will pain be controlled?
• How will nausea be managed?
• What happens if there is blood loss?
• Will blood be immediately available?
• Will my child wake up with the breathing tube out?
• Can I be with my child when anesthesia starts?
• When can I see my child after surgery?

Children’s Health’s pediatric anesthesia FAQ covers these same parent concerns, including general anesthesia, mask or IV induction, breathing tube, monitoring, blood loss preparation, arterial lines, recovery, feeding, and when parents may see the child after surgery. (Children's Health)

Ask:

• Is transfusion likely for this surgery?
• What is my child’s blood type?
• Has blood been crossmatched?
• What blood products might be used?
• What hemoglobin level would trigger transfusion?
• Will labs be checked during surgery?
• Do you use medications to reduce bleeding?
• Do you use cell salvage, if appropriate?
• What are the risks of transfusion?
• What are the risks of not transfusing if blood loss is significant?
• Can parents donate blood?
• What if we have religious or personal concerns?

ASPS includes “Will surgery require a blood transfusion?” in its craniosynostosis consultation checklist, and Children’s Health explains that when blood loss is anticipated, matched blood is kept available and monitoring tools may be used to replace blood loss safely. (American Society of Plastic Surgeons)

Ask:

• Was the planned surgery completed?
• Was there anything unexpected?
• Was a transfusion needed?
• Is my child stable?
• Is the breathing tube out?
• Where will my child go next?
• What swelling should we expect tonight?
• What pain medicines are being used?
• When can my child eat?
• What are the main concerns for the first night?
• When will we talk again with the surgical team?
• What should we watch for overnight?

The practical takeaway:

After surgery, ask concrete questions. You may not remember a long explanation, so focus on stability, breathing, transfusion, location, pain, feeding, and next steps.

Red Flags After Surgery Day

Follow your discharge instructions and hospital team guidance. Call the team promptly if your child has:

Fever

Increasing incision redness

Incision drainage

Bleeding that does not stop as instructed

Clear fluid leakage

Repeated vomiting

Poor feeding

Unusual sleepiness

Difficulty waking

Trouble breathing

Seizure-like activity

Bulging soft spot

Worsening swelling after discharge

Pain not controlled by medication

New weakness or unusual movement

Helmet rubbing incision or causing skin breakdown, if helmet therapy is used

Device-site redness or drainage, if springs or distractors were used

ASPS lists serious craniosynostosis surgery risks that include infection, bleeding, CSF leak, swelling, transfusion-related risks, recurrence of raised intracranial pressure, and need for revision surgery, which is why discharge warning signs should be taken seriously. (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, has clear fluid leakage, or seems seriously ill.

Common Parent Fears

“Will my baby feel pain during surgery?”

General anesthesia is designed so your child is unconscious, does not feel pain, and does not remember the operation. Children’s Health explains that general anesthesia prevents memory formation and eliminates pain during surgery, while CHOP states that children sleep through the procedure and wake with no memory of what happened. (Children's Health)

“Will anesthesia be safe?”

Pediatric anesthesiologists are trained to care for children before, during, and after surgery. Children’s National states that its anesthesia is administered by fellowship-trained pediatric anesthesiologists, and Children’s Health explains that the anesthesiologist monitors the child and adjusts medication based on age, weight, pain level, heart rate, blood pressure, and breathing. (Children's National Hospital)

“Will my child need a blood transfusion?”

It depends on the surgery. Open cranial vault surgery is more likely to need transfusion, while endoscopic surgery is less likely. Mayo Clinic and Seattle Children’s both describe transfusion as usually or likely needed for open surgery and usually less likely or not needed for endoscopic surgery. (Mayo Clinic)

“Does ICU mean something went wrong?”

Not necessarily. ICU care is often planned after open craniosynostosis surgery and sometimes after endoscopic surgery depending on the center. Seattle Children’s includes ICU time in typical hospital stays for open cranial vault reconstruction, fronto-orbital advancement, and endoscopic pathways. (Seattle Children's)

“Will we get updates?”

Ask your hospital’s specific process. Seattle Children’s states that families get updates every couple of hours while the child is in the operating room and speak with the surgeon after surgery. (Seattle Children's)

“What if I cannot handle the waiting?”

You do not have to wait perfectly. Bring a charger, water, snacks if allowed, a notebook, and one support person if permitted. Children’s National specifically recommends bringing something to occupy your time while waiting, such as a charger, magazines, knitting, or laptop. (Children's National Hospital)

How to Explain Surgery Day to Family Members

Here is a simple explanation:

“Craniosynostosis surgery day includes check-in, pre-op preparation, anesthesia, surgery, and recovery or ICU monitoring. Our child will be under general anesthesia so they are asleep and pain-free. The surgical team has a blood plan because skull surgery can involve bleeding, especially open cranial vault surgery. We will receive updates while we wait, and the surgeon will talk to us after the operation. We may not respond to every message during the day, but we will update everyone when we can.”

This can help relatives understand why parents may need space, time, and fewer texts during surgery.

Craniosynostosis surgery day usually includes check-in, pre-op evaluation, anesthesia, surgery, recovery, and close monitoring afterward.

General anesthesia is used so the child is asleep, pain-free, and does not remember the surgery.

The anesthesia team should know about allergies, medicines, breathing issues, reflux, prematurity, seizures, sleep apnea, previous anesthesia, family anesthesia history, recent illness, and transfusion concerns.

Fasting instructions matter because food or stomach acid can enter the lungs during anesthesia if the stomach is not empty.

Open cranial vault surgery is more likely to involve blood transfusion than endoscopic surgery.

Endoscopic strip craniectomy is generally less likely to require transfusion, but bleeding planning still matters.

Blood crossmatch means compatible blood is prepared in case transfusion is needed.

Parents should ask about blood conservation, transfusion likelihood, IV lines, arterial lines, and how blood loss will be monitored.

ICU care after craniosynostosis surgery is often planned monitoring, not necessarily a complication.

Waiting-room updates vary by hospital, so ask how often and by what method you will hear from the team.

Parents should bring chargers, water, snacks if allowed, comfort items, documentation, and a communication plan.

After surgery, ask whether the planned operation was completed, whether transfusion was needed, whether the child is stable, whether the breathing tube is out, and when you can see your child.

The simplest parent-friendly summary is:

Craniosynostosis surgery day is a long day with many moving parts. The most important parent tasks are to follow fasting instructions, give the anesthesia team complete information, understand the blood and transfusion plan, know how updates will happen, and ask clear questions when the surgeon comes out.

Frequently Asked Questions About Craniosynostosis Surgery Day

What happens on craniosynostosis surgery day?

Surgery day usually includes hospital check-in, pre-op assessment, meeting the surgical and anesthesia teams, general anesthesia, surgery, parent updates, recovery room or ICU transfer, and close monitoring afterward. Seattle Children’s states that families receive updates during surgery and meet with the surgeon afterward. (Seattle Children's)

Will my child be under general anesthesia?

Yes, craniosynostosis surgery is usually done under general anesthesia. Children’s Health defines general anesthesia as medications that cause loss of consciousness, prevent memory, and eliminate pain during surgery. (Children's Health)

Will my baby remember surgery?

No. Under general anesthesia, children sleep through the procedure and do not remember what happened. CHOP states that children under general anesthesia sleep through the procedure and wake with no memory of it. (Children's Hospital of Philadelphia)

Will my child go to sleep with a mask or an IV?

It depends on age, medical history, and anesthesia plan. Children’s Health explains that some children fall asleep with anesthesia air through a mask and then receive an IV after they are asleep, while older children or some younger children may have an IV placed before surgery if safer. (Children's Health)

Will my child need a breathing tube?

Often, yes. A breathing tube is commonly used during general anesthesia for major surgery. CHOP explains that children under general anesthesia may need a breathing tube so they can breathe properly during surgery. (Children's Hospital of Philadelphia)

Can I be with my child when anesthesia starts?

Maybe. This depends on the hospital and anesthesiologist. Children’s National says parent presence during anesthesia start may be allowed at the anesthesiologist’s discretion in selected non-emergency cases, while Children’s Health says parents generally do not stay in sterile operating rooms but may sometimes accompany a child until they fall asleep. (Children's National Hospital)

Why are fasting instructions so important?

Fasting helps reduce the risk of vomiting with aspiration during anesthesia. HealthyChildren.org states that if fasting instructions are not followed, surgery may need to be delayed or rescheduled for safety. (HealthyChildren.org)

What if my child has a cold or fever before surgery?

Call the surgical team. Children’s National advises calling the surgeon immediately if the child has a cold, fever, rash, or fever blister because surgery may need to be postponed. (Children's National Hospital)

Is blood loss expected during craniosynostosis surgery?

Some blood loss is expected because craniosynostosis surgery involves skull bone and scalp tissue. The amount depends on the procedure. Open cranial vault surgery generally has more transfusion discussion than endoscopic surgery. Mayo Clinic states that open surgery usually needs blood transfusion, while endoscopic surgery usually does not. (Mayo Clinic)

Will my baby need a blood transfusion?

It depends on the surgery type and the child. Seattle Children’s lists open cranial vault surgery as likely to need transfusion and endoscopic strip craniectomy as less likely to need transfusion. (Seattle Children's)

What does blood crossmatch mean?

Blood crossmatch means the blood bank prepares compatible blood in case transfusion is needed. ASPS states that before craniosynostosis surgery, children may be asked to get lab testing and a crossmatch for blood to be transfused. (American Society of Plastic Surgeons)

What should I ask about transfusion?

Ask whether transfusion is likely, whether blood is crossmatched, what blood conservation strategies are used, what transfusion threshold the team uses, what risks and benefits apply, and what happens if blood is needed urgently.

Will my child go to the ICU?

Possibly. ICU monitoring is common after open craniosynostosis surgery and may also occur after endoscopic surgery depending on the hospital. Seattle Children’s lists ICU time in typical hospital stays for open cranial vault surgery, fronto-orbital advancement, and endoscopic strip craniectomy. (Seattle Children's)

How long will surgery take?

It depends on the operation. Seattle Children’s lists open cranial vault surgery as 3 to 5 hours, endoscopic strip craniectomy as 1 to 2 hours, and fronto-orbital advancement as 4 to 5 hours in its parent-facing materials. (Seattle Children's)

Will we get updates while waiting?

Ask your hospital. Seattle Children’s states that families receive updates every couple of hours during surgery and receive a pager while waiting. (Seattle Children's)

What should parents bring to the waiting room?

Bring phone chargers, a portable charger, water, snacks if allowed, a notebook, medications you need, layers, headphones, and something quiet to do. Children’s National recommends bringing something to occupy your time while waiting, such as a phone and charger, magazines, knitting, or laptop. (Children's National Hospital)

When will we see our child after surgery?

Timing depends on recovery room or ICU stabilization. Children’s Health explains that parents are called to the bedside once the recovery nurse feels the child is stable, though timing can vary depending on the child’s medical needs. (Children's Health)

What will my child look like after surgery?

Swelling and bruising can occur, especially after open surgery. ASPS lists swelling and bruising, including temporary eye swelling shut, among craniosynostosis surgery risks and recovery issues. (American Society of Plastic Surgeons)

What should I ask the surgeon after surgery?

Ask whether the surgery was completed as planned, whether anything unexpected happened, whether transfusion was needed, whether your child is stable, whether the breathing tube is out, where your child will go next, and when you can see them.

What symptoms after surgery should prompt urgent attention?

Call the team for fever, incision drainage, worsening swelling, repeated vomiting, poor feeding, unusual sleepiness, difficulty waking, trouble breathing, seizure-like activity, bulging soft spot, clear fluid leakage, or pain not controlled by medication. Seek urgent care if your child is difficult to wake, has trouble breathing, has repeated vomiting, has seizure-like activity, or seems seriously ill.
