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, doctors only applied dehydration, sedative and anti-vomiting drugs to temporarily relieve acute symptoms during vertigo attacks, and no drugs were taken during intervals or limited to Cipro and vertigo stop, which generally felt that it was not ideal to control re-attacks, i.e. it could not effectively treat the primary lesion of the disease. 1.Hallpike cold and heat change temperature test This method is the most commonly used, about 1/3 of the patients have normal response, 1/3 have weak response, and the other 1/3 have complete loss. cawthorne et al. performed cold and heat change temperature test on 900 cases, 640 cases of tube light paralysis, 75 cases of dominant bias, 108 cases of both appearing together, and 26 cases of unknown records. It can be seen that the largest number of cases had tubular paralysis and dominant bias. Vestibular function was most severely impaired during the first 5 years of the disease and was consistent with cochlear function impairment. Sometimes, in order to simplify the examination in the outpatient clinic, ice water 2ml is used to flush the posterior upper quadrant of the tympanic membrane and qualitative results can be obtained. Myerhoff (1981) examined 211 cases of ENG and found that 21% of those with normal response, 65% of those with mild paralysis of the tube, and 14% of those with dominant deviation. The presence of the syndrome could not be excluded in those with normal response. The sweep, visual tracking test and optokinetic examination were normal, and the rotation test and DC stimulation examination were either diminished or normal in function. Recently, someone used sinusoidal harmonic acceleration (SHA) vestibular function examination, the stimulation can be repeated and controlled, three parameters of phase gain, phase retardation and dominance bias can be obtained, with phase retardation being the most sensitive, with phase retardation being the most sensitive, and with phase gain being the most ideal for combined application. 3.Other The neurological examination is not abnormal. The ear drum is normal. According to Cole (1972), out of 250 cases, 25 (10%) showed otosclerotic lesions in both sides of the vagus. The enlargement of the internal auditory canal in the presence of an auditory neuroma can also be excluded. The otoscopic examination showed normal tympanic membrane and good function of the eustachian tube. The hearing impairment was cochlear (positive resonance test, negative fatigue test, etc.) and the damage in the lower register was more severe. The hot and cold test of vestibular function was performed during the interictal period, and most of them were hemianopsia of the affected side; the glycerol test was mostly positive. Combining the above symptoms and examination data has diagnostic value for this disease.
