Craniosynostosis

Symptoms

The most common sign of craniosynostosis is an irregularly shaped head. You may also be able to feel a ridge along the skull where the suture has closed. There may be no other symptoms when craniosynostosis affects only a single suture. Misshapen heads can also be caused by other factors or conditions that are unrelated to craniosynostosis, such as the birthing process or your baby's sleep position.

Although most cases of craniosynostosis are diagnosed based on an irregularly shaped head, illness may also be a sign. Craniosynostosis is usually more severe when more than one suture closes too early. This significantly restricts the skull's ability to expand as the brain grows. As pressure builds on the brain, your baby may:

• Vomit.
• Become sluggish, sleep more, and play less.
• Become irritable because of head pain.
• Develop swollen eyes or problems moving the eyes or following objects.
• Have problems hearing.
• Breathe noisily or have periods of not breathing (apnea).

When the pressure is very severe, it may cause brain damage and other problems, including seizures, blindness, and developmental delays. Untreated craniosynostosis may cause permanent disabilities.
