Middle Cranial Fossa Perspective with Petrosectomy. This is a right lateral view of the parasellar region featuring the cavernous ICA and oculomotor, trochlear, trigeminal, and abducens nerves. Most of the petrous portion of the temporal bone has been removed (petrosectomy) to expose several of these structures. (Image courtesy of AL Rhoton, Jr.)
