ASC -BPPV 的眼震电图定位模式及反式 CRP的临床应用

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。

Diagnostic model of VNG for ASC-BPPV and clinical application trans-CRP

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 proce-dure （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 differ-ent 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 semicir-cular 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.
