我科近两年对用药物治疗无效的10例美尼尔氏病试行内淋巴囊减压术,其中随访1年半以上者4例。这4例中,男女各2例;年龄和病程分别为:24岁,8个月;28岁,8个月;32岁,4年和56岁,18年;均左耳病变.乳突和内听道平片及体层摄影正常.前庭功能检查:1例无反应,2例减弱,1例正常.纯音测听:4例语言频率气导平均为65dB.阈上测听:短增量敏感指数试验均得分75％以上.双耳交替响度平衡试验3例阳性,1例无法测.强度辨差阈3例均在1dB以内,1例未测.音衰试验均为阴性.语言测听:语言识别率1例为
In recent two years, we treated 10 cases of Meniere’s disease with ineffective drug therapy for endolymphatic sac decompression. Among them, 4 cases were followed up for more than one and a half years. The 4 cases were male and 2 female, with age and course of disease of 24 years and 8 months respectively, 28 years and 8 months, 32 years, 4 years, 56 years and 18 years, Internal auditory canal plain film and normal tomography. Examination of vestibular function: one case no response, two cases weakened, one case normal. Pure tone audiometry: 4 cases of language frequency of air conduction average 65dB. Upper threshold audiometry: short increment Sensitive index test scores were more than 75% .Abital alternating loudness balance test was positive in 3 cases, 1 case can not be measured.The intensity difference threshold in 3 cases were within 1dB, 1 case was not tested. : Language recognition rate of 1 case
