What is the pterion area?
The pterion is the H-shaped formation of sutures on the side of the calvarium representing the junction of four skull bones: the greater wing of the sphenoid bone. squamous portion of the temporal bone. frontal bone.
For what structure is the pterion used as a landmark?
The pterion which marks the union of 4 bones of the cranium is located superior to the zygomatic arch and posterior to the frontozygomatic suture. It is an important neurosurgical landmark for the lateral/pterional approach and has racial differences in both its location and pattern of union of the bones.
