oxycephaly

Turricephaly is a type of cephalic disorder where the head appears tall with a small length and width. It is due to premature closure of the coronal suture plus any other suture, like the lambdoid, or it may be used to describe the premature fusion of all sutures. It should be differentiated from Crouzon syndrome. Oxycephaly (or acrocephaly) is a form of turricephaly where the head is cone-shaped, and is the most severe of the craniosynostoses.
