Abstract
A transsigmoid approach is detailed for removal of tumors involving the jugular foramen. This approach was used in seven patients, eliminates the need for facial nerve transposition, and helps to preserve cochleovestibular function. The sigmoid sinus is packed and both the facial nerve and the labyrinth are identified. This approach provides excellent vision of the intradural and extradural course of the lower cranial nerves, rendering preservation of isolated nerves within the neural compartment feasible.
