The Temporal Bone: Anatomical Dissection and Surgical Approaches

The patient underwent a gross total resection of the tumor via a transcochlear approach. The neoplasm was found to fill the entire petrous apex and involve the intrapetrous portion of the carotid canal, but it was easily dissected from the internal carotid artery.

The patient underwent removal of the lesion via a transcochlear approach with facial nerve translocation.

Primary melanoma of the petrous temporal bone

(1,12,14) Large tumors with anterior and inferior extension approaching the clivus and jugular foramen, respectively, typically require an extended transcochlear approach, including facial nerve transposition.
