Facial nerve neuroma

Facial nerve neuromas are uncommon, slow-growing neoplasms that may occur anywhere along the course of the facial nerve from the brainstem to the facial muscles. The signs and symptoms are characteristic and vary with the anatomic site of origin. Surgery should not be attempted until a complete and thorough diagnostic examination has been completed. The surgeon should be prepared to perform a middle-cranial fossa or translabyrinthine approach in all cases, and must expect to do a nerve graft. The results of 37 patients treated by the author reveal that, under optimal conditions, patients who have had a facial nerve graft, can be expected to regain an average of 80% facial nerve strength in almost every case. All patients who have had a facial nerve graft will have some degree of synkinesis. No graft was required in 3 patients, and a hypoglossal facial anastomosis was used for one. Facial function was completely normal in 2 patients, 16 had 80-90% return, 5 patients had 50-80% return, 4 had 20-50% return, one had no recovery at all and 9 recent patients have not reached the time for their expected recovery. Early diagnosis, prompt surgical removal and VII-VII Nerve graft for facial paralysis of ten or fewer years duration offers patients the best opportunity to avoid a permanent facial palsy.
