Craniosynostosis is a birth defect that causes one or more sutures on a baby's head to close earlier than normal.
The skull of an infant or young child is made up of bony plates that allow for growth of the skull. The borders at which these plates intersect are called sutures or suture lines. The sutures between these bony plates normally close by the time the child is 2 or 3 years old.
Early closing of a suture causes the baby to have an abnormally shaped head.
The cause of craniosynostosis is unknown. Genes may play a role. However, there is usually no family history of the condition.
One type that is passed down through families (inherited) can occur with other health problems, such as seizures, decreased intelligence, and blindness. Genetic disorders commonly linked to craniosynostosis include Crouzon, Apert, Carpenter, Chotzen, and Pfeiffer syndromes.
However, most children with craniosynostosis are otherwise healthy and have normal intelligence.
Types of craniosynostosis:
The doctor will feel the infant's head and perform a physical exam.
The following tests may be done:
Well-child visits are an important part of your child's health care. They allow your doctor or nurse to regularly check the growth of your infant's head over time. This will help identify any problems early.
Surgery is done while the baby is still an infant. The goals of surgery are:
How well your child does depends on:
Children with this condition who have surgery usually do well, especially when the condition is not associated with a genetic syndrome.
Craniosynostosis results in head deformity that can be severe and permanent if it is not corrected. Increased intracranial pressure, seizures, and developmental delay can occur.
Call your child's health care provider if:
Premature closure of sutures
