Pronounced: Krooz-on SIN-drom
by Rick Alan
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 once we are adults since 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.
Crouzon syndrome is caused by a defect in a specific gene. It is not clear what causes this gene to mutate. Some may be inherited from parents genes.
Factors that may increase your child's risk of Crouzon syndrome include having:
The main signs and symptoms of Crouzon syndrome include:
Other symptoms and complications that can result from Crouzon syndrome include:
A doctor can usually diagnose Crouzon syndrome based on physical signs and symptoms.
The doctor may need images of the skull. These can be taken with:
Your doctor may also do genetic testing to confirm the diagnosis.
There is no cure yet for Crouzon syndrome. Currently, many of the symptoms can be treated with surgery.
Treatment may include:
There are a number of surgeries used to treat the symptoms of Crouzon syndrome. These include:
Orthodontic treatment can help correct the alignment of teeth. It may include braces.
Specialist should monitor infants and children with Crouzon syndrome. These specialists can check for eye and ear problems and treat as necessary.
Children with a mental deficiency or intellectual disability may need special education help.
There is no known way to prevent Crouzon syndrome. If you have Crouzon syndrome or have a family history of the disorder, you can talk to a genetic counselor when deciding to have children.
