Craniosynostosis is a condition in which one or more of the sutures in a baby’s skull fuse prematurely, restricting skull growth and potentially altering head shape and intracranial development. Craniosynostosis-related discussions often cover both isolated (nonsyndromic) cases and those associated with broader genetic syndromes.

Causes and classification include genetic and environmental factors, with a spectrum from isolated nonsyndromic forms to syndromic craniosynostosis. Syndromic craniosynostosis occurs with recognized genetic conditions such as Crouzon, Apert, Pfeiffer, Saethre-Chotzen, and Muenke syndromes, and may involve multiple sutures, facial features, and other organ systems. Mutations in genes such as FGFR2, FGFR3, and TWIST1 are commonly implicated. The affected sutures include the sagittal, coronal, metopic, and lambdoid, among others, and the pattern of fusion influences head shape and clinical considerations.

Presentation typically includes an abnormal skull shape noted early in infancy, with potential signs of increased intracranial pressure, visual or breathing concerns, and facial asymmetry. Diagnosis relies on physical examination and imaging, commonly computed tomography with 3D reconstruction, supplemented by genetic testing when a syndrome is suspected.

Management is tailored to the individual and often involves a multidisciplinary team. Surgical options aim to release fused sutures and restore normal skull growth and facial balance; approaches range from minimally invasive endoscopic procedures for selected infants to more extensive cranial vault remodeling and frontoorbital advancement for others. Helmet therapy or orthotic devices may be used in select milder cases or postoperatively. Ongoing monitoring focuses on brain development, vision, airway function, and growth.

Prognosis improves with early recognition and appropriate treatment, though outcomes vary with the severity and whether a syndromic context is present. Regular follow-up with neurosurgery, plastic surgery, genetics, pediatrics, ophthalmology, and other specialists is common.
