Is craniofacial morphology in Apert and Crouzon syndromes the same?

This article reviews previous research on the craniofacial development in A pert and Crouzon syndromes and adds new roentgencephalomehic information. I t is concluded that craniofacial development in the two syndromes is not th e same. Marked differences were found in the calvaria, cranial base, orbit, maxilla, zygoma, incisal occlusion, and soft tissue profile.
