What is Craniosynostosis?
Craniosynostosis occurs when the bones of the baby's skull fuse together before the brain has stopped growing. The top of a baby's skull consists of five bones that are held together by fibrous material called sutures. These sutures should stay open while the baby's brain is still growing. If even one of the sutures closes prematurely, it can result in a misshapen skull or face. Craniosynostosis can happen before the baby is born or during the first few months of life.
