Pronounced: Krooz-on SIN-drom
Crouzon syndrome is a genetic disorder. It results in abnormal joining of the bones in the skull and face.
Infants have sutures between the bones in the face and skull. As an infant’s brain grows, these sutures allow the skull to expand. These sutures fuse together when we are adults and our skulls and brains are done growing.
In Crouzon syndrome, the bones in the skull and face fuse too early. The skull is then forced to grow in the direction of the remaining open sutures. This causes an abnormally shaped head, face, and teeth.
