* Fracture F is a diastatic fracture that follows the squamosal and sphenoparietal sutures of the left temporal and is more visible on the endocranial surface (Figure 3).
(2) Type B (normal discontinuous): in a discontinuous BVR, the anterior part drains into the sphenoparietal sinus or cavernous sinus through an uncal vein and posterior part drains to the vein of Galen.
While one fracture is relatively minor, the other radiated along the squamosal, sphenoparietal, and coronal sutures before traveling through lesion i and dissipating at lesion ii.
The Pterion was first classified into three types (sphenoparietal, frontotemporal and stellate) by Broca in 1875.
Fig 3 shows that the sphenoparietal type is a sutural pattern in which the sphenoid and parietal bones are in direct contact, preventing the frontal and temporal bones making contact with one another.
RESULT: Sphenoparietal type of pterion accounted 86.25% (90% on the right side and 82.5% on the left side), frontotemporal 11.25% (12.5% on the right side and 10% on the left side) and stellate 2.5% (5% on the right side) in all 40 skulls.
DISCUSSION: In primate evolution, the anterosuperior segment of the squamous part of the temporal bone of lower primates became detached from its parent and incorporated into the posterosuperior angle of the greater wing of the sphenoid bone of humans, thereby changing the pterion pattern from the frontotemporal type of nonhuman primates to the sphenoparietal type of humans (9).
Sphenoparietal type of pterion is most common in all the regions.
Epipteric type of pterion was not encountered in the present study, this is significant as in Nigerians it accounts 23.6% (13), Australian Aborigines 18.5% (16), and in other Indian studies it ranges from 6.74% to 11.79% which was mostly associated with sphenoparietal type (10,17).
