Syndromic craniosynostosis affects up to 1:30,000 live births with characteristic craniofacial growth restrictions, deformities, and other associated abnormalities, such as carpal-pedal anomalies and cognitive function impairment. More than 150 syndromes are associated with craniosynostosis. This article describes some commonalities and distinguishing features and management of syndromic synostosis. Also addressed is secondary synostosis, which is often found in syndromic children with problems related to microcephaly, hydrocephalus, or shunt-induced craniosynostosis, although pathophysiologically and genetically different. The importance of obtaining a thorough history and a complete physical and examination is highlighted. Adjuvant testing and multidisciplinary management are discussed.

Craniosynostosis, in which 1 or more cranial sutures prematurely fuse, is associated with diverse environmental and genetic factors. Whereas isolated single-suture synostosis is usually sporadic and nonfamilial, FGFR mutations account for most cases of syndromic craniosynostosis. This article reviews the etiology and various clinical manifestations of the most common isolated and syndromic forms of craniosynostosis, and provides a brief overview of genetics. Past and present surgical management approaches and techniques are examined in depth. Outcomes data in the recent literature are reviewed, and controversies in the field and promising trends in craniofacial surgery discussed.
