This is a demonstration of using the transventricular and subtemporal corridors for resecting a large middle fossa, tentorial meningioma. The video details the microsurgical technique for detaching the tumor from the tentorial incisura, working near critical structures such as the oculomotor nerve, trochlear nerve, and posterior communiating artery. It also includes precise demonstration of how to separate the massive tumor from the feeding arterial supply stemming from the posterior cerebral artery.
