What is craniosynostosis?

A newborn baby’s skull consists of several bones that fit together. Usually, newborns have spaces called sutures between their skull bones. The sutures let the skull size grow to accommodate the baby’s growing brain. When the bones of the skull are fused together either at birth or fuse too soon, the condition is called craniosynostosis.

The sutures of the skull fuse around the brain at around age 2 years. When a baby has craniosynostosis, one or more of these sutures hardens too early and closes before the baby reaches age 2.
