Magnified Endoscopic View of Right Anteromedial Aspect of Petroclival Area

Surgical Correlation


Magnified endoscopic view of right anteromedial aspect of petroclival area. Petrosal and clival bone have been removed to expose the internal carotid artery (at left border of image) and the anterior pons (at right border). The abducens nerve is shown coursing from the lower ventral pons through a remnant of clival bone and dura into the cavernous sinus on the lateral surface of the internal carotid artery. The anterior inferior cerebellar artery can be seen arising from the proximal portion of the basilar artery and looping toward the internal auditory meatus in company with the facial and auditory nerves. The trigeminal nerve emerges from the lateral pons and courses toward the petrous apex. Posterior and inferior to it is a portion of the vein of the middle cerebellar peduncle. (Image courtesy of AL Rhoton, Jr.)
