Types of Craniosynostosis
Craniosynostosis can be categorized into many types. These types are known by different names that depend upon on which suture is involved. This include –
Sagittal Synostosis (Scaphocephaly):
Scaphocephaly is the premature fusion of the sagittal suture. A head which is narrow from ear to ear and is elongated from front to back is termed as Scaphocephaly. The condition of Scaphocephaly can be corrected with the help of different techniques. The purpose of every treatment is to obtain a more normal shape that includes making the skull wider from side to side and shortening the skull from front to back. This enables for more normal growth. Techniques used for each patient is different. Endoscopic approach or Calvarial Vault Remodeling (CVR) surgery can also be used.
Metopic Synostosis (Trigonocephaly) :
This type is the fusion of the forehead (metopic) suture. This suture travels through the top of the head reaching down the middle of the forehead, near the nose. Its early closure can cause major ridge running down the forehead. In this the forehead looks pointed similar to a triangle having closely placed eye.
Coronal Synostosis (Plagiocephaly):
This type includes fusion of either left or right side of the coronal suture running from ear to ear. This is termed as coronal synostosis that leads to normal forehead but stops the growth of the brow.
When there is a premature fusion of one of the coronal sutures then it causes asymmetric forehead and brow. This is considered as the second most common type of synostosis. As compared to right, left side unicoronal synostosis is more common.
