Craniosynostosis is the premature fusion of one or more sutures in the skull of a newborn. It occurs in 1 in 2000 live births. Below is a picture of what a normal skull looks like. Growth of the skull occurs at each of the sutures so when one closes too early growth from that suture is inhibited and malformation occurs.
In the case of my boys, the sagittal suture fused too early inhibiting the growth from going side to side and causing the growth to go out the front and back. Giving them the elongated head.
The ONLY treatment for craniosynostosis is surgery! If left untreated, kids may experience intercranial pressure, inhibited brain growth, or developmental delays, among other things. Diagnosing it early is so important!!
