NEURILEMMOEMA of the facial nerve within the temporal bone is rare with a wide range of clinical symptomatology. Three diverse cases have been encountered by the senior author (G.E.S.), and one additional case by Valvassori. Report of Cases CASE 1.—History.—A 60-year-old white woman, referred with a "tumor deep in the right ear," had been diagnosed one week previously as having a neurilemmoma of the facial nerve on the basis of a surgical biopsy performed by the referring physician. Approximately eight months earlier the patient had consulted the referring physician because of "buzzing" and a pounding tinnitus in her right ear, with a slight hearing loss. At this time the Weber test lateralized to her right ear, and the Rinne test was negative on the right at 256 and 512 cycles per second (cps). She had also noted a slight facial asymmetry with decreased movement on the right, which had slowly progressed.
