Sagittal slit prematurity is a congenital malformation of cranial development caused by premature closure or bony fusion of the sagittal cranial suture in the vault of the skull. As a result, the narrow cranial cavity is unable to accommodate normal brain development, and children often exhibit developmental delay, brain dysfunction, mental retardation, cognitive dysfunction, protruding eyes, elevated intracranial pressure, visual impairment, speech and mental activity abnormalities, developmental delays, and epileptic seizures. Surgery is the only effective treatment for sagittal suture prematurity. The purpose of surgery is to enlarge the cranial cavity, reduce the cranial pressure to better meet the growth and development of the brain, and to improve the shape of the skull to avoid the abnormal head shape and the psychosocial damages caused to the children. Sagittal suture premature closure, should seek professional doctors as early as possible, the implementation of surgical treatment, in order to help improve the cranial deformity, reduce the deformity caused by the increase in intracranial pressure and alleviate the developmental disorders of brain tissue.
