Ménière病前庭及听功能相关性分析

为了解Meniere病患者的位听功能，对按AAO－HNS标准诊断为Meniere病121例（166耳）患者的临床检查结果，进行追溯性研究。位听功能统计结果证明：①耳蜗与前庭受损程度有相关性，经趋势及x2检验为正相关（P＜0．01），即听力损失越重半规管不对称比值越大：②听力损失与ECochG优势－SP有关，听力损失越重，－SP／AP异常率越高，差异有显著性。③听力损失与甘油试验阳性率有关，轻度受损甘油试验阳性率低（22．2％），听力损失严重者甘油试验的阳性率增高（84．6％），差异有显著性，ECochG与甘油试验比较，前者更敏感；④各种听力图中上坡及峰型曲线甘油试验阳性率最高为69．0％，下坡及槽型曲线阳性率为33．3％，差异有显著性。诊断Meniere病客观依据不多，听力图、ECochG、前庭功能、甘油试验等联合检查是重要的诊断依据和选择治疗的准则。

Vestibular and auditory functions in Meniere's disease

This paper is, aiming at understanding distt1rhances of and correlations between cochlear and vestibular functions in Meniere's disease.Auditory and vestibular functions in 121 Meniere cases (70 males and 51 females, age ranging from 19 to 63 years), diagnosed according to the AAO-HNS criteria, were analysed. The results were as follows: 1)There was positive correlation between semicircular canal paresis and hearing im-pairment. 2) There was statistically significant positive correlation between hearing impairment and the -SP/AP ratio. 3)There was statistically significant correlation between hearing impairment and glycerin test result, the rate of positive result being higher in those with advanced hearing loss than in those with mild loss. 4)There was correlation between the rate of positive glycerin test result and audiogram configuration. The rate with rising audiogram pattern was higher than with that falling pattern (69. 0% vs 33. 3% ). It was also found that ECochG was far more effective than glycerin test in diagnosing Meniere's disease. The physiologic basis and significance of ECochG and glycerin test in Meniere's disease were discussed.
