Scaphocephaly

Scaphocephaly, or sagittal craniosynostosis, is a type of cephalic disorder which occurs when there is a premature fusion of the sagittal suture. Premature closure results in limited lateral expansion of the skull resulting in a characteristic long, narrow head. The skull base is typically spared.

Scaphocephaly is the most common of the craniosynostosis conditions and accounts for approximately 50% of all craniosynostosis. It is most commonly idiopathic (non-syndromic).
