摘　　要：目的 :观察梅尼埃病 (MD)患者前庭小管 (VA)周围骨质发育情况。方法 :实验分三组 :正常耳组 ,非MD眩晕组及 MD组。每组 VA均行 CT扫描 ,并测量后半规管至颞骨岩部后面的最短距离 (PP值 )及后半规管至水平半规管的最短距离 (PL值 )。结果 :MD患者 VA显影率低 ,PP值明显小于正常耳组及非 MD眩晕组。结论 :VA及其周围骨质发育障碍是Objective:To study the development of the bone around the vestibular aqueduct (VA) in Meniere′s disease (MD) by CT.Method:The experiment consisted of three groups:normal ear group,non MD vertigo group and MD group.VA in each group was examined by CT,and the minimum distance between the posterior semicircular canal and the posterior petrous surface where contain the endolymphatic sac.Result:VA visualization rate in MD was low,P P distance in MD group was shorter than that of normal ear group and non MD vertigo group.Conclusion:It is the fundamental pathological anatomy in MD that VA and the bone around VA are maldeveloped.
