Craniosynostosis is a rare skull problem that causes a baby to be born with, or develop, an abnormally shaped head.
The irregular skull shape in craniosynostosis can cause persistent headaches, learning difficulties, eye problems and other symptoms. Most symptoms develop in later childhood.
The symptoms of craniosynostosis usually result from increased pressure within the skull, which is called Intracranial Pressure (ICP).
Different types of craniosynostosis can be described based on the areas of the skull affected and the resulting changes in shape.
