Pterion
The pterion is the region where the frontal, parietal, temporal, and sphenoid
join together. It is located on the side of the skull
Pterion clinical anatomy
- pterion is an in
important area because it overlies the middle meningeal artery - fracture to pterion can rupture the anterior branch of artery resulting in hematoma which exerts pressure on the underlying cerebral cortex.
- an untreated meningeal artery can cause haemorrhage which can lead to death in a few hours
