What Is Sagittal Synostosis?
Sagittal Craniosynostosis is a condition in which the soft joint running along the top of the skull (the sagittal suture) fuses earlier than usual. The head becomes narrower and longer from front to back than usual — a shape called Scaphocephaly.
How It Affects Your Child
Besides the long, narrow head, it causes bossing (bulging) of the forehead and a bullet-shaped back of the skull (occiput). In very rare circumstances it can compress the brain and raise the pressure inside the skull.
How It Is Diagnosed
Your craniofacial surgeon will first examine your child thoroughly. A skull X-ray and a 3D CT scan of the head are usually needed; occasionally an MRI is also done to assess the brain.
How It Is Treated
Treatment is surgical and is carried out by a multidisciplinary team led by the craniofacial surgeon and neurosurgeon. Dr Vybhav Deraje leads the Craniosynostosis team at Aster Whitefield Hospital, Bangalore. The type of operation depends on your child's age.
Under 6 months of age: minimally invasive, endoscope-assisted keyhole surgery to remove the fused suture, followed by Orthotic Helmet Therapy. Above 6 months: an open operation called Cranial Vault Remodelling to reshape the skull.
Keyhole (Endoscopic) Surgery — What to Expect
Before surgery your child is assessed by a paediatric neuro-anaesthetist and has an eye check. Admission is on the day of surgery. The operation takes 1–2 hours under general anaesthesia. Because it needs only a small cut in the scalp, there are no major scars and no major blood loss, although a blood transfusion is occasionally needed.
Your child stays in the ICU overnight, where pain is well controlled by the critical care team, and normal feeding is encouraged. Your child moves to the ward the next day and usually goes home on the third day, after the head dressing is removed. You can give a normal head shower after that.
After Keyhole Surgery: Orthotic Helmet Therapy
After a check one week after the operation, Orthotic Helmet Therapy is started with the orthotic partner and continues until a good head shape is achieved; the helmet may need to be changed once or twice depending on progress. You will see the craniofacial surgeon and neurosurgeon at regular intervals.
Open Cranial Vault Remodelling — What to Expect
Before surgery your child is assessed by a paediatric neuro-anaesthetist and an ophthalmologist. Admission is on the day of surgery. The operation is done under general anaesthesia and usually takes 4–5 hours. Several monitoring lines (such as a central line and an arterial line) are placed, and almost all children need a blood transfusion during and after surgery.
The cut runs across the top of the head from one ear to the other. The neurosurgeon protects the brain while the craniofacial surgeon reshapes the skull bones. The bones are usually fixed with stainless-steel wires or stitches; absorbable plates and screws are used occasionally. The wound is closed with absorbable stitches and a head bandage is applied.
Your child spends the first night in the ICU and then moves to the ward. Expect marked swelling of the head and face — the eyes may close for 3–4 days — which settles over the week. Children usually go home on the sixth or seventh day, after the bandage is removed, and can have a head shower after that.
After Open Surgery
You will have periodic follow-up with the craniofacial surgeon and neurosurgeon. This is usually a one-time operation: if there is no associated syndrome, it is all your child will need. Orthotic Helmet Therapy is not needed after open remodelling. Small gaps in the skull close over within 2–3 years, and the scar is usually well hidden in the hair.
Possible Complications
This is major surgery and families should be fully informed. Infection, bleeding, scarring, swelling and pain are the common complications, and the team manages them routinely. A small tear in the covering of the brain is sometimes seen and is usually repaired during the operation. Injury to the eye or brain is very rare. Death is a remote theoretical possibility; Dr Deraje's team has not seen it in their practice.
Travelling from Another State or Country?
Families come to Dr Vybhav Deraje from across India and abroad. Send your child’s photographs and CT scan to the clinic first — Dr Vybhav can review them on a video consultation, and the clinic confirms the dates before you book travel. Keyhole surgery is possible only before 6 months of age, so contact the clinic early.

Frequently Asked Questions
What does Sagittal Craniosynostosis look like?
The head is long from front to back and narrow from side to side (Scaphocephaly), often with a bulging forehead and a pointed, bullet-shaped back of the head.
How is Sagittal Craniosynostosis diagnosed?
Your craniofacial surgeon will first examine your child thoroughly. A skull X-ray and a 3D CT scan of the head are usually needed; occasionally an MRI is also done to assess the brain.
What is the best age for Sagittal Craniosynostosis surgery?
Under 6 months of age, minimally invasive endoscope-assisted keyhole surgery is possible, followed by Orthotic Helmet Therapy. Above 6 months, an open Cranial Vault Remodelling is done.
How long is the hospital stay?
Usually about 3 days after keyhole surgery (one night in the ICU) and 6–7 days after open surgery.
Is a helmet needed after surgery?
Yes after keyhole surgery — Orthotic Helmet Therapy follows the operation. No after open remodelling surgery.
Other Types of Craniosynostosis
- Metopic Synostosis — Triangular, keel-shaped forehead (Trigonocephaly).
- Unicoronal Synostosis — One side of the forehead flattened, with a slanted skull (Anterior Plagiocephaly).
- Bicoronal Synostosis — Both coronal sutures fused — a flat, wide head (Brachycephaly).
- Lambdoid Synostosis — Back of the head slanted or twisted to one side — the rarest type.
- Multisuture & Syndromic Craniosynostosis — Several sutures fused, often with a syndrome such as Crouzon or Apert.
