ABSTRACT
The authors report three patients of large petroclival meningiomas which were operated by retrolabyrinthine(petrosal) approach. This technique maximizes temporal bone drilling and therefore provide exquisite exposure of the clival and petrous regions with minimal brain retraction. The superior petrosal sinus is sacrificed and the tentorium completely cut. The sigmoid sinus on the other hand can be preserved, depending on the venous drainage and the degree of exposure required.
Key Words: Petroclival; Meningioma; Petrosal approach
