Tapeisocephaly (low head) is due to synostosis of the great wings of the sphenoid with the frontal.
Trochocephaly (roundness of head) is due to partial synostosis of the frontals and parietals in the centre of the coronal suture.
Simple dolichocephaly is due to synostosis of the sagittal, or antero-posterior suture of the skull.
This process of synostosis begins from the interior of the cranium, and only subsequently manifests itself externally.
As a result, osseous solidification of the joint (synostosis) ensues without, of course, the possibility of any movement.
