Sagittal synostosis.

Sagittal synostosis causes predictable malformations depending on the specific suture location that fuses. Anterior fusion causes frontal bossing, whereas posterior fusion causes an occipital knob. Complete sagittal synostosis results in deformity both anteriorly and posteriorly. Variants of each type exist and therefore surgical correction must be tailored to the individual patient. Examples of the different forms of sagittal synostosis are discussed, and the various surgical techniques available are detailed.
