[Acoustic neuroma and others tumors of the angle, and internal auditory meatus. Surgical results and choice of the approach (126 cases) (author's transl)].

126 tumors of the angle and I.A.C. (118 acoustic neuromas) have been operated by the author from 1966 to 1978. The surgery was done either by the middle fossa, or the translabyrinthine, or the retrosigmoid approach. The perservation of the Facial nerve is obtained in 93%, the facial function is normal in 70%. The hearing is preserved after removal of the tumor in 50% of the intracanalar neuromas, and in 35% after removal of tumors expanded in the angle.
