Transzygomatico Subtemporal Approaches for Upper Clival,Cavernous Sinus and Cranial Middle Fossa Base Tumors

Six patients with petrosal clival or middle fossa base tumors were operated upon through transzygo-matic subtemporal approaches.The zygomatic arch was translocated,the base of lateral middle cranial fossa was exposed,the upper wall of external auditory canal and part of petrosa were removecl with microdrill so that the re-tract injury of temporal lobe is minimal. And the brainstem. cranial nerves and hypothalamus are well protected with excellent exposure of the tumors via subtemporal route.Surgical results of these patients were good.The op-erative approaches and brain retract injury are discussed.
