Crouzon Disease, also known as Crouzon Syndrome or Craniofacial Dysostosis Type 1, is a congenital disorder characterized by abnormal growth of the skull and facial bones. It is caused by a genetic mutation. The condition is named after a French physician, Octave Crouzon, who first described it in 1912. Synonyms for Crouzon Disease include Crouzon Syndrome, Craniofacial Dysostosis Type 1, and CFD1. These terms are often used interchangeably to refer to the same condition. Crouzon Disease affects the shape of the head and face, leading to features like a flattened midface, shallow eye sockets, and a protruding forehead. It can also cause hearing loss and dental issues. Early diagnosis and treatment are important to prevent complications and manage symptoms.
