[Surgery of acoustic tumors by the retro-sigmoid route. A personal technique. Results on audition and the facial nerve (61 cases) (author's transl)].

In the surgery of acoustic tumors it is possible to preserve audition and, indeed, imperative, if the neuroma is bilateral. In this work, we describe our technique by the retro-sigmoid route which allowed us to preserve hearing in 36% of cases and facial motor movements in 82% of cases (61 operations).
