Different names are given to the various types of craniosynostosis. The names depend on which suture or sutures are involved. This article will discuss plagiocephaly, trigonocephaly, scaphocephaly, and Crouzon's syndrome. There are other syndromes involving craniosynostosis. Most of these other syndromes, however, are similar in some way to the conditions discussed here.
Plagiocephaly occurs most often.
It happens in approximately one out of 2,500 births. It involves fusion of either the right or left side of the coronal suture. The fusion, or early closure, of the coronal sutures on one side causes the normal forehead and brow to stop growing forward. This causes a child with plagiocephaly to look as if the forehead and brow are pushed backwards. The eye on the affected side also has a different shape.
