【摘要】：目的探讨不同听力分期梅尼埃病(Meniere disease,MD)患者眼肌前庭诱发肌源性电位(ocular vestibular evoked myogenic potential,oVEMP)及冷热试验(caloric test)的特征及临床意义。方法对确诊的MD患者55例(52.8±15.8岁),按MD听力分期标准分为1期9例(48.8±13.8岁),2期9例(46.0±16.3岁),3期23例(50.3±13.5岁),4期14例(53.5±16.2岁),分别行oVEMP检测及冷热试验,分析其结果。结果 1、2、3、4期MD患者oVEMP异常率分别为55.6%(5/9)、66.7%(6/9)、78.3%(18/23)、78.6%(11/14),冷热试验异常率分别为22.2%(2/9)、33.3%(3/9)、78.3%(18/23)、85.7%(12/14);可引出oVEMP的1、2、3、4期MD患者其振幅分别为4.3±4.0、3.5±2.3、2.5±2.4、1.3±0.5μV。结论 MD患者oVEMP及冷热试验异常率随其听力受损程度加重呈上升趋势,oVEMP振幅呈下降趋势,提示椭圆囊与水平半规管的损伤加重。
[Abstract]:Objective to investigate the characteristics and clinical significance of (ocular vestibular evoked myogenic potential,oVEMP and (caloric test) in different hearing stages of Meniere's disease (Meniere disease,MD). Methods 55 patients (52.8 卤15.8 years old) with MD were divided into 9 stage 1 (48.8 卤13.8 years old), 9 stage 2 (46.0 卤16.3 years old), 23 stage 3 (50.3 卤13.5 years old) and 14 stage 4 (53.5 卤16.2 years old) patients according to the standard of MD hearing stage. The results were analyzed. Results 1 the abnormal rates of oVEMP were 55.6% (5 / 9) 66.7% (6 / 9) 78.3% (18 / 23) 78.6% (11 / 14) in stage 4 MD patients and 22.2% (2 / 9)% (2 / 9) in cold and hot tests, respectively, and the amplitudes were 4.3 卤4.03.5 卤2.43 卤2.43 卤0.5 渭 V in patients with MD of stage 1, 2 / 3, 78.3% (18 / 23) and 85.7% (12 / 14), respectively, and the amplitudes were 4.3 卤4.03.5 卤2.3 卤2.5 卤2.41.3 卤0.5 渭 V, respectively. Conclusion the abnormal rate of oVEMP and cold and hot test in MD patients is increasing with the degree of hearing impairment. The amplitude of oVEMP is decreasing, which suggests that the damage of elliptic sac and horizontal semicircular canal is aggravated.
