Crouzon syndrome--A case report.

Crouzon syndrome is a genetic disorder also known as branchial arch syndrome. Specifically, this syndrome affects the first branchial (or pharyngeal) arch, the precursor of the maxilla and mandible. Since the branchial arches are important developmental features in a growing embryo, disturbances in their development create lasting and widespread effects. Previously referred to as craniofacial dysostosis, the disorder is characterized by a number of clinical features; to date, it has no known single, initiating defect to account for all its characteristics. This article presents a case report of a 10-year-old boy with classical skeletal and soft tissue features of Crouzon syndrome.
