The coronal suture runs from the top of the skull down the sides towards the corner of the eye.

Severe and obvious cases will require surgery, while mild cases may need no surgery or limited surgery at a later date. There are varying degrees of deformity in trigonocephaly. This head shape is known as trigonocephaly. This runs up the middle of the forehead and when fused, may cause an angled forehead with a crest (pointed area) in the middle of the forehead and a swept back appearance to the eyebrow and temple bones. The second most common fusion occurs in the metopic suture. The forehead often becomes tall and pushes forward (referred to as frontal bossing) while the back of the skull may become pointed or narrowed. This head shape is known as scaphocephaly. This results in a head shape that is long from front to back and narrow from side to side. This suture runs from the front to the back along the middle of the skull. The most common suture to fuse early is the sagittal suture. Types of single suture fusions Sagittal suture It’s likely that the baby’s genes have developed abnormally, however there is no definitive evidence for this yet. The condition is not usually genetically transferred from parent to child. How many babies are affected and what causes it?įusion of a single suture in the skull occurs in about 1 in 3000 births. In rare cases, craniosynostosis is caused by certain genetic syndromes (syndromic craniosynostosis). This causes the head to grow into an unusual shape.Ĭraniosynostosis usually involves fusion of a single cranial suture, but can involve more than one of the sutures in your baby’s skull (complex craniosynostosis). These sutures allow the skull to be squashed slightly as baby travels down the birth canal and enable the head to grow normally in the first years of life.Ĭraniosynostosis occurs when one or more of the fibrous joints between the bones of a baby’s skull (cranial sutures) close prematurely (fuse), before the brain is fully formed.Īs the brain continues to grow, it pushes on the skull from the inside, but cannot expand into the area that is closed over. In a newborn baby, the skull is made of bone plates that are joined together by flexible areas known as sutures.
