摘　　要：目的：通过良性阵发性位置性眩晕（BPPV）患者前庭诱发肌源电位（VEMP），包括颈性VEMP和眼性VEMP的特性研究，以探讨其对眩晕定位诊断的价值。方法：对67例对照组和33例BPPV患者分别进行颈性VEMP、眼性VEMP检测，分析比较两组之间各项检测数据的差异。结果：①病例组患耳的颈性VEMP、眼性VEMP异常率分别达到33％和36％；②病例组与对照组的颈性VEMP各波潜伏期比较差异有显著意义，但峰一峰波幅比较差异无显著意义。病例组与对照组眼性VEMP各波潜伏期和峰一峰波幅比较差异有显著意义。结论：VEMP可以作为（BPPV）耳石器功能异常变化的客观量化评估指标，并对眩晕的定位诊断提供一定帮助。Objective： To investigate the characteristics of vestiblar evoked myogenic potential （VEMP） cervical VEMP,ocular VEMP of patients with benign paroxy-sma[ vertigo（in BPPV）, and find out the value of VEMP in vertigo iocalting diagnosis. Methods： To investigate the characteristics of cVEMP, oVEMP by testing 67 healthy people and to assess the difference by comparing the data of af- fected ears of 33 BPPV patients with those obtained from healthy people. Results： （1）The rate of abnor- mal cervical VEMP and ocular VEMP is 33% and 360%, respectively; （2）There was significant difference in cervical VEMP and ocular VEMP between affected ears of the patient group and healthy people. Con- clusion：cervical VEMP and ocular VEMP can be adopted as clinic indicator for changing of the otolithic organs,and to localting diagnosis for vertigo.
