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. The word comes from Ancient Greek σκᾰ́φη (skáphē) 'boat' and κεφαλή (kephalḗ) 'head'.

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