Scaphocephaly

scaphocephaly

Craniosynostosis is premature closure of the cranial sutures. The skull shape undergoes characteristic changes depending on which suture(s) close early. The sagittal suture is most commonly involved, where lateral growth of the skull is arrested while anteroposterior growth continues, producing a narrow elongated skull known as scaphocephaly (meaning boat-shaped) or dolichocephaly. Causes are primary, or secondary to certain haematologic disorders, metabolic disorders, bone dysplasias and syndromes. There is a 3:1 male predominance. Treatment is cranioplasty.
