Skull Reduction Surgery (Cranial Vault Remodeling) for Craniosynostosis

Cranial vault remodeling (often called cranioplasty in this context) is the primary surgical treatment for craniosynostosis—premature fusion of one or more cranial sutures that restricts skull growth and brain development.

Indications

• Single-suture (sagittal, coronal, metopic, lambdoid) or multisuture synostosis.
• Elevated intracranial pressure, developmental delay, or significant cranial deformity.
• Typically performed between 3–12 months of age for optimal bone plasticity.

Surgical Techniques

• Open remodeling: Bicoronal incision; affected bones removed, reshaped, and repositioned with absorbable plates/sutures. Gold standard for complex/multisuture cases.
• Endoscopic strip craniectomy: Minimally invasive; suturectomy via 1–2 small incisions + postoperative helmet molding. Best for single-suture, <6 months old.
• Spring-assisted distraction: Springs placed across osteotomy sites for gradual expansion; second surgery for removal.

Multidisciplinary Team

Neurosurgeon + craniofacial plastic surgeon + anesthesiology + NICU/PICU + genetics + ophthalmology + developmental pediatrics.

Outcomes

• Normalizes head shape and intracranial volume.
• Reduces ICP; supports neurodevelopment.
• Scars hidden in scalp; long-term aesthetic and functional results excellent in experienced centers.

Early diagnosis (clinical exam + 3D CT) and referral to a craniofacial center are critical.
