【摘要】：目的:探讨检测眼肌前庭诱发肌源性电位(oVEMP)和颈肌前庭诱发肌源性电位(cVEMP)对单侧原发性良性阵发性位置性眩晕(BPPV)患者进行可能发病部位的定位诊断价值。方法:对52例单侧原发性BPPV患者(BPPV组)和38例正常人(对照组)分别进行气导短纯音诱发的oVEMP和cVEMP检测,分析两种反射的引出率、潜伏期、振幅等数据。结果:BPPV组患侧oVEMP的引出率为46.15%,cVEMP的引出率为67.31%;其健侧oVEMP的引出率为48.08%,cVEMP的引出率为65.38%。对照组左侧oVEMP的引出率84.21%,cVEMP的引出率92.11%;右侧oVEMP的引出率为81.58%,cVEMP的引出率为94.74%。对照组双侧cVEMP和oVEMP的P1、N1潜伏期及N1-P1振幅值差异均无统计学意义。BPPV组和对照组cVEMP和oVEMP耳间振幅比及不对称率差异有统计学意义(P0.05)。结论:单侧原发性BPPV患者双侧前庭耳石器传导通路功能受损状况,可以通过oVEMP和cVEMP检测进行客观评估,并且oVEMP的异常率比cVEMP高。
[Abstract]:Objective: to investigate the diagnostic value of detecting the oculomuscular vestibular evoked myogenic potential (OVEMPP) and the cervical vestibular evoked myogenic potential (CVEMPP) in patients with unilateral benign paroxysmal positional vertigo (BPPV). Methods: oVEMP and cVEMP were detected in 52 patients with unilateral primary BPPV and 38 normal subjects (control group). The extraction rate, latency and amplitude of the two reflexes were analyzed. Results the extraction rate of oVEMP in the affected side was 46.15 and that of camp in the control group was 67.31, and that of oVEMP in the healthy side was 48.08 and 65.38 respectively. In the control group, 84.21% of left oVEMP and 92.11% of cVEMP were extracted, while the rate of oVEMP in right side was 94.74%, 81.58% and 94.74%, respectively. There was no significant difference in P1N 1 latency and N1-P1 amplitude of bilateral cVEMP and oVEMP in control group. There were significant differences in amplitude ratio and asymmetry rate between cVEMP and oVEMP in BPPV group and control group (P 0.05). Conclusion: the functional impairment of bilateral vestibular otochoid conduction pathway in patients with unilateral primary BPPV can be evaluated objectively by oVEMP and cVEMP, and the abnormal rate of oVEMP is higher than that of cVEMP.
