Synostosis is the fusion of bones during development and occurs along the suture lines of the skull. If the synostosis occurs prematurely, the normal expansion of the cranial vault may be prevented, resulting in abnormal shape or asymmetry. The growth inhibition occurs at right angles to the closed suture. and is affected by the order and timing of closure relative to the closure of the other sutures.
