摘　　要：目的:分析梅尼埃病患者水平半规管高低频前庭功能的特点。方法:收集2013-06-2014-06期间30例就诊于我院神经内科眩晕专病门诊确诊为单侧梅尼埃病患者,分别进行冷热试验及视频脉冲甩头试验检查。结果:按冷热试验时患侧半规管轻瘫程度分为正常组、轻度异常组及中重度异常组,随后对各组患者水平半规管高频功能进行分析。视频脉冲甩头试验中半规管增益值反应水平半规管的高频功能,统计发现其在正常组及轻度异常组间的差异无统计学意义(P>0.05),而在正常组与中重度异常组、轻度异常组与中重度异常组组间差异有统计学意义(P<0.05);半规管增益不对称性反应两侧水平半规管高频功能的对称性,统计发现其在正常组与轻度异常组、正常组与中重度异常组、轻度异常组与中重度异常组间的差异无统计学意义(P>0.05)。结论:部分梅尼埃病患者可不出现半规管高低频功能损害。低频功能轻度损害时高频功能基本正常,低频功能中重度损害时才出现高频功能受损,但高频功能两侧对称性基本不变。Objective： To analyze the feature of horizontal semicircular canal function at high and low-frequencies in Menieres disease. Method：Thirty patients suffering from unilateral Meniere＇s disease were included in the research from 2013 June to 2014 June. Caloric test and video head impulse test were performed to evaluate the high,low-frequency function of horizontal semicircular canal. Result： these patients were derided by the severity of unilateral weakness in caloric test. The gain value in video head im- pulse test, which reflects the high-frequency function of semicircular canal, were not different between the normal and mild abnormal group （P〉0.05）, but were obviously different between the normal and mild-severe abnormal group, slight abnormal and mild-severe abnormal group （P〈0.05）. Gain asymmetry, which reflects the high-fre- quency function of both side, has no difference between three groups （P〉0.05）. Conclusion：A part of Meniere＇s disease may have normal high,low-frequency function of horizontal semicircular canal. As patient suffering slight injury of low-frequency function, the high-frequency function keeps normal. As the injury of low-frequency func- tion become mildly to severely, the damage of high-frequency function appears, but the symmetry still keeps balance.
