TL;DR: Results indicate that implant subjects can score significantly above chance on a variety of discrimination tests and score significantly better than hearing aid subjects on these tests.
Abstract: Thirty-three adult subjects have been implanted with single-electrode cochlear implants at the Ear Research Institute. This paper outlines the current status of the subjects; the rehabilitation and testing program; results found with the implant; and future directions of the implant program. Results indicate that implant subjects can score significantly above chance on a variety of discrimination tests. Implant subjects also score significantly better than hearing aid subjects on these tests. Research is continuing on engineering and signal-processing improvements for the single-elecrode implant. Multiple-electrode implants and binaural implants are being considered for future research at the Ear Research Institute.

TL;DR: A patient with Meniere's disease underwent a middle fossa superior and inferior vestibular nerve section with excision of Scarpa's ganglia, and studies of this patient's temporal bone, conducted two and one-half years post-operatively, showed normal cochlear and facial nerves.
Abstract: A patient with Meniere's disease underwent a middle fossa superior and inferior vestibular nerve section with excision of Scarpa's ganglia. Studies of this patient's temporal bone, conducted two and one-half years post-operatively, showed normal cochlear and facial nerves. The internal auditory canal showed fibrosis and new periosteal bone formation. There was complete denervation of the vestibular labyrinth except for the posterior semicircular canal crista. Fibrous and osteoid tissue filled the superior and lateral semicircular canals. In this case, these severe degenerative changes, presumably associated with biochemical changes in the vestibular labyrinth, altered the natural course of Meniere's disease. Vertigo was completely relieved, tinnitus improved, and hearing thresholds stabilized during the course of post-operative follow-up.

TL;DR: Members of the Otologic Medical Group, Inc, Los Angeles, diagnose Meniere's disease in patients with fluctuating hearing loss, fluctuating tinnitus, episodic vertigo, and fluctuating pressure symptoms in the ear.
Abstract: • Members of the Otologic Medical Group, Inc, Los Angeles, diagnose Meniere's disease in patients with fluctuating hearing loss, fluctuating tinnitus, episodic vertigo, and fluctuating pressure symptoms in the ear. Treatment is vasodilation. If medical treatment fails, an endolymphatic subarachnoid shunt operation is performed. If the shunt relieves symptoms for three or more months but symptoms then recur, revision of the shunt is recommended. If the revision surgery also fails, a destructive procedure is suggested.
