Craniosynostosis

[Justin Bieber]

Craniosynostosis is premature fusion of one or more calvarial sutures.

(See also Introduction to Congenital Craniofacial and Musculoskeletal Disorders and Overview of Congenital Craniofacial Abnormalities.)

Premature fusion of sutures causes a characteristic skull deformity due to decreased growth in a direction perpendicular to the closed suture. It occurs in 1 of 2500 live births. There are several types, depending on which suture is fused.
