摘要:

目的　探讨应用眼震电图检查前半规管良性位置性眩晕（ASC-BPPV）眼震电图定位模式的合理性，评价在此诊断基础上采用反式Epley耳石复位法（T-CRP）的疗效。　方法　　收集8例诊断为ASC-BPPV患者的临床资料。其中右侧ASC-BPPV 6例，左侧ASC-BPPV 2例，病程1周～6月。所有病例均进行眼震电图定位模式定位后行反式CRP治疗，观察其临床疗效。　结果　　8例ASC-BPPV的眼震表现均符合ASC-BPPV眼震电图定位模式，经反式CRP治疗后8例眩晕均得到不同程度缓解，总有效率达100%。5例达到痊愈效果，占62.5%，3例治疗有效，占37.5%。　结论　　ASC-BPPV的眼震电图定位模式符合临床客观资料，其与内耳解剖密切相关，临床上反式CRP是针对ASC-BPPV的一种有效治疗方案。

Abstract:

[Abstract] Objective　To explore effective mode for locating diagnosis of anterior semicircular canal-benign paroxysmal positional vertigo(ASC-BPPV) depending on Videonystagmography and treatment of trans-canalith repositioning procedure (T-CRP).　Methods　We Collected 8 cases diagnosed as ASC-BPPV. 6 cases of them were the right ASC - BPPV, 2 cases were the left ASC - BPPV, The length of duration of disease was 1 week to 6 months. All cases were diagnosed by Videonystagmography T-CRP on the basis of the mode of locating diagnosis of ASC-BPPV were applied to eight cases of ASC-BPPV,then the feature of VNG of them and clinical therapeutic effect were evaluated. 　Results　The feature of VNG in the eight cases of ASC - BPPV consistent with the mode for diagnosis of ASC-BPPV,Vertigo of 8 cases inclined to different degree resolution of symptoms during period of follow-up after treatment with trans CRP. Total effective rate was 100%. and five of them were cured finally (62.5%) and three cases were effective (37.5%).　Conclusion　The diagnosis model of ASC-BPPV was more consistent with the clinical data,which was closely related to the dissection of the semicircular canal,The T-CRP therapy is an effective therapeutic schedule for ASC-BPPV and should be applied for all patients who were diognosised to the ASC-BPPV.
