One of the clinical symptoms of fluctuating hearing loss Meniere’s disease is manifested. In addition to spinning, vomiting and unbearable pain of patients during attacks, Meniere’s syndrome can also cause damage to the vagus, vestibular and cochlear organs, resulting in death of cochlear hair cells and loss of vestibular function, causing deafness, ataxia and other harmful effects, which are irreversible lesions and will not be cured by present-day medicine. In addition, in middle-aged and elderly patients, multiple attacks may affect the cerebrovascular regulation and cerebral microcirculation, thus aggravating the lack of cerebral blood supply and triggering cerebral infarction. In the past, general doctors only applied dehydration, sedative and anti-vomiting drugs to temporarily relieve acute symptoms during vertigo attacks, and no drugs were taken or limited to Cipro or vertigo stop during the interval, which generally felt that it was not ideal to control re-attacks, i.e. it was not effective to treat the primary lesion of the disease. The auditory function shows typical cochlear lesions. 1.Pure tone audiometry The early stage shows low-frequency sensorineural deafness, the middle stage is mostly flat, the attack period is aggravated, the attack can be partially or completely recovered in a fluctuating hearing curve, the late stage shows a stable declining curve, the hearing loss is mostly between 50 to 70dB 5 to 10 years after the onset. 2, language audiometry language hearing threshold and pure tone hearing threshold has a good correlation, due to sound distortion, language discrimination rate can be reduced to 40% ~ 70%. According to Stahle (1976), 356 patients were followed up for years, the general speech acceptance threshold was 62 dB, the resolution was 52%, and the pure tone loss was at 55 dB on average. 3. Suprathreshold functional examination Binaural alternating loudness balance test (ABLB) was positive. The sound intensity discrimination threshold (DLI) is lower than 0,6dB, and the short incremental sensitivity index (SISI) is elevated to more than 80%, suggesting the phenomenon of auditory resonance. 4.Impedance audiometry examination: type A ventricular force, no sound failure and sound reflex attenuation, stapedius muscle reflex threshold and hearing threshold difference below 60dB, called Metz positive, also suggests the phenomenon of resonance. 5.Bekesy self-tracing audiometry shows type II curve. 6, cochlea electrogram SP/AP amplitude ratio >37%, Gibson reported that the increase of SP-AP wave width ratio is more meaningful than the increase of amplitude ratio.
