What is Crouzon syndrome?
Crouzon syndrome is a rare, genetic condition that causes the bones in the skull to fuse too early (craniosynostosis). This premature fusing causes the skull to grow abnormally and affects the head and the face. Many of the facial features seen in Crouzon syndrome are also the result of this early fusion and include abnormal growth of the bones that cause wide-set and bulging eyes, vision problems that may include strabismus (eyes that do not point in the same direction) and a jaw that is underdeveloped. Other common features of Crouzon syndrome include dental problems, hearing loss, narrow ear canals, and spine abnormalities. Signs and symptoms of Crouzon syndrome vary. The intelligence of people with Crouzon syndrome is typically normal.
