Abstract
This work describes the exposure of the intrapetrous internal carotid artery (ICA) through the subtemporal approach. Bone drilling in the meatal plane anterior to the internal auditory canal could create a four-sided quadrangular area.
The exposure of the ICA through this area was applied in three occasions.
It proved safe as regards the surrounding structures and also provided an ample working space for the extirpation of tumours surrounding the artery.
