No sagittal keel and no parasagittal flattening are observable. The variation in thickness in this area is mainly due to the presence of the sagittal sinus that constitutes a depression on the endocranial surface and therefore a decrease in bone thickness. On the right parietal bone and anteriorly to the depression, a small foramen is visible.15.3 Craniosynostosis. Early or abnormal closure of any cranial suture is referred to as craniosynostosis and can result in an abnormality of head shape (). 6,? 7 The most common craniosynostosis is premature closure of the sagittal suture (sagittal craniosynostosis), which impairs widening of the skull and results in a compensatorily increased anteroposterior (AP) dimension of the skull.
