Craniofacial Surgery

Craniosynostosis is the premature fusion of one or more of the fibrous joints (sutures) between the skull bones, which normally remain open during the first 12 to 18 months of life to allow the rapidly growing brain to expand the skull. When a suture fuses prematurely, the skull cannot expand perpendicular to the fused suture and compensates by abnormally expanding in other directions — creating a characteristic skull deformity. More critically, in multi-suture craniosynostosis, the constrained skull can raise intracranial pressure, impair cerebral blood flow, cause optic nerve compression (threatening vision), and restrict cognitive development. Surgical correction is medically necessary — not merely cosmetic.

Each suture fusion produces a recognizable skull shape: Sagittal synostosis (most common, 50%) fuses the midline sagittal suture, producing a long, narrow skull (scaphocephaly or dolichocephaly). Coronal synostosis (uni- or bilateral) fuses the coronal suture(s), causing a tall, flattened forehead (anterior plagiocephaly or brachycephaly) and orbital asymmetry. Metopic synostosis fuses the triangular frontal suture, producing a pointed, ridged forehead (trigonocephaly). Lambdoid synostosis causes posterior skull flattening (posterior plagiocephaly). Syndromic forms (Apert, Crouzon, Pfeiffer, Muenke syndromes) involve multiple sutures with associated midface underdevelopment.

Timing depends on the suture involved and surgical technique chosen. For endoscopic (minimally invasive) strip craniectomy, surgery is ideally performed between 2 and 4 months of age — when bone is pliable and brain growth pressure naturally reshapes the skull post-operatively with the aid of a cranial remodeling helmet. Open cranial vault remodeling (CVR) or fronto-orbital advancement (FOA) can be performed between 6 and 12 months, allowing greater bone strength for reshaping and rigid fixation. Multi-suture syndromic craniosynostosis may require earlier intervention and staged surgeries as the child grows.

After endoscopic strip craniectomy, a custom-fitted cranial orthosis (remodeling helmet) is essential to guide the released skull into a normal shape as the brain grows. Helmeting begins 2 to 4 weeks post-operatively and is worn 23 hours per day for 3 to 12 months, with adjustments every 4 to 8 weeks as the skull reshapes. After open cranial vault remodeling, the skull is actively reshaped intra-operatively with fixation plates and absorbable sutures — helmeting is typically not required post-operatively, as the reconstructed skull holds its new shape immediately.

Studies consistently demonstrate that surgical correction of craniosynostosis in the first 6 to 12 months of life significantly reduces intracranial pressure, prevents optic atrophy, and is associated with improved neurodevelopmental outcomes compared to untreated cases. Children corrected early track normal cognitive and language developmental milestones in the majority of cases. Some children with syndromic craniosynostosis may have underlying developmental differences related to their genetic syndrome; these are managed with early neuropsychological assessment, occupational therapy, and speech therapy as part of comprehensive craniofacial team care.

Craniofacial surgery is inherently multidisciplinary. At Olive, the craniofacial team includes: a plastic and craniofacial surgeon (skull and facial reconstruction), a pediatric neurosurgeon (brain and dural protection), a pediatric anesthesiologist experienced in neonatal and pediatric airway management, an ophthalmologist (monitoring orbital pressure and vision), an orthodontist (managing dental arch and jaw development), a geneticist (evaluating for syndromic diagnoses), and a speech-language pathologist. This coordinated team approach ensures every dimension of craniofacial care is addressed throughout childhood and adolescence.
