The video demonstrates the resection of a trigeminal schwannoma via a middle fossa craniiotomy and anterior petrosectomy. A large dumbbell-shaped tumor was essentially two tumors in one. The anterior petrosectomy provided access mainly to the posterior component of the tumor, which was compressing the pons, and obscured by the tentorium and petrous ridge. Mobilization of the lateral wall of the cavernous sinus freed the anterior component and thus allowed the removal of the rest of the schwannoma.
