Scaphocephaly. The sagittal suture lies along the midline of the skull. Shape of the head One of the most common signs of scaphocephaly is an elongated head shape . In mammals, the jugal is often called the zygomatic bone or malar bone. In this type, the anterior or posterior portion of the sagittal suture closes prematurely; the resulting compensatory growth causes frontal bossing. Metopic craniosynostosis is a type of non-syndromic craniosynostosis that occurs when the metopic suture fuses before birth. Sagittal synostosis is the most common type, accounting for 40-55% of nonsyndromic craniosynostosis. 1.
