The incidence of Menière's disease was investigated in a total of 3222 patients with vertigo or dizziness who had visited Kitasato University Hospital during 1985-1991. Two hundred and fifty-one of the cases (7.8%) were found to suffer from Menière's disease and the male:female ratio was 1:1. Seventy cases of Menière's disease with complete records were classified into five groups, depending on the duration of the illness since its onset. Both ears were affected in 12 (17.1%) of the patients but in 4 (33.3%) of prolonged 12 patients having more than 15 years after the onset. All 70 patients had been treated conservatively, except for 3 who had undergone surgery. Frequency of vertiginous attacks and hearing impairment during the last year in each group were retrospectively compared with those of the other groups. No vertiginous attacks were experienced in 13 (24.1%) cases. The average number of vertigo attacks during the last year was 4.5 per year in 49 cases. Adequate therapy is desirable within one year after the onset of Menière's disease: the results showed the frequency of vertiginous attacks to be lowest and hearing levels to be best in the first group who were treated less than one year after the onset, in comparison with the other prolonged cases.
1985年至1991年期间，对3222名因眩晕或头晕前往北里大学医院就诊的患者进行了梅尼埃病发病率的调查。其中251例（7.8%）被诊断为梅尼埃病，男女比例为1:1。将70例记录完整的梅尼埃病患者根据发病后的病程分为五组。12例（17.1%）患者双耳受累，但在发病15年以上的12例病程较长的患者中，有4例（33.3%）双耳受累。除3例接受手术治疗外，其余70例患者均接受了保守治疗。回顾性比较了每组患者去年眩晕发作的频率和听力损害情况，并与其他组进行了对比。13例（24.1%）患者未经历眩晕发作。49例患者去年眩晕发作的平均次数为每年4.5次。梅尼埃病发病后一年内进行适当治疗是可取的：结果显示，与其他病程较长的病例相比，发病后不到一年接受治疗的第一组患者眩晕发作频率最低，听力水平最佳。
