In this procedure, the provider removes a portion of skull bone and excises a cerebellopontine angle tumor, or acoustical neuroma. The provider uses a dual approach, exposing the nerve through a transtemporal approach, meaning across the temporal bone, and through the middle, or posterior fossa, to obtain a wide exposure of the skull to access the tumor while minimizing brain retraction. The goal of this procedure is to remove the tumor while maintaining existing hearing and facial function.
