Anatomical consideration of pterion and its related references in Thai dry skulls for pterional surgical approach.

The pterion is predominantly sphenoparietal type and is typically located 39 mm superior to the zygomatic arch, 31 mm posterior to the frontozygomatic suture, 39 mm lateral to the optic canal and 12 mm from the sphenoid ridge. The data obtainedfrom the present study should be clinically useful for localizing the position of pterion.
