Apert Syndrome

In Apert syndrome there is also coronal suture fusion leading to brachycephaly as well as poor development of the middle of the face and upper jaw. The skull is a little different than with Crouzon, tending to be of a larger size, with a very prominent forehead which may grow upward in a tower-like fashion (turricephaly).

Patients with Apert syndrome also have severe complex webbing of the fingers and toes, which is called syndactyly. They may have anomalies of the brain as well as an abnormal drainage of fluid around the brain (hydrocephalus).
