Babies who develop sagittal synostosis are found to be just as intelligent . Cranial CT shows premature bony fusion of the sagittal suture with associated ridging along the suture line and resultant impediment of the lateral and continuing anteroposterior growth of the skull with an elongated and narrow skull deformity. Craniosynostosis is a birth defect in which the bones in a baby's skull join together too early. This study was designed to evaluate the effect of a total calvarial reconstruction on skull development in patients with nonsyndromic sagittal synostosis. Craniosynostosis refers to a condition in which the fibrous joints (the sutures) between the bones of a baby's skull fuse premature.

The occipital bone is a cranial dermal bone and the main bone of the occiput 9; see also Figure 7 Vomer Groove for As with the sagittal crest, an occipital bun allows more surface area for muscle, thus permitting larger jaws As with the sagittal crest, an occipital bun allows more surface area for muscle, thus permitting larger jaws. The skull and forehead are not allowed to move sideways and forwards leading to closely placed eyes (hypotelorism). In sagittal craniosynostosis, all or part of the sagittal suture fuses before birth, leading to the skull being long from front to back but narrow from side to side. In terms of morphologic phenotypes, sagittal synostosis is seen in 40% to 55% of nonsyndromic cases. Sagittal synostosis is the most common form of craniosynostosis affecting roughly 1 in 5,000 babies at birth, with a greater incidence among boys than girls, roughly 4 to 1.

Patients with sagittal craniosynostosis exhibit a typical cranial appearance, including scaphocephaly, and an elongated head, with a fused and ridged sagittal suture. OFC remains close to normal, but the biparietal diameter is markedly reduced. We had a CT scan that day and they confirmed it and suggested we do the surgery in the next 2 weeks. Objective: To identify and review research on individuals with SS and to determine whether, and to what extent, they experience cognitive, behavioral, and psychological difficulties compared with their healthy peers .

How dangerous is surgery for Craniosynostosis? It produces scaphocephaly, which is characterized by a narrow, elongated cranial vault and reduced bitemporal dimension (the basic "toaster head"). Sagittal craniosynostosis (scaphocephaly) is the most common form of isolated craniosynostosis. The skull compensates by growing longer in the front and back, with a very large forehead and narrow pouched out back of the skull.
