摘　　要：目的:探讨眼震电图(ENG)及动态姿势描记(DPG)2种前庭功能检查在良性阵发性位置性眩晕(BPPV)中的临床应用。方法:应用ENG与DPG对40例34～79岁的原发性BPPV患者(BPPV组)和20例正常者(对照组)进行检查,其中DPG评定参数选取感觉器官测试(SOT)中前庭感觉评分、本体感觉评分、视觉评分、Romber′s评分和综合评分。结果:40例BPPV患者的ENG检查中,温度试验异常者26例(65.0%);DPG异常者33例(82.5%),并且DPG中均表现为前庭觉评分低,其他几项评分均未见差别。温度试验和DPG两项结果均异常者24例(60.0%),温度试验正常患者中有9例(64.3%)出现前庭觉评分低,在SOT中除前庭觉评分低外其他几项评分均未见明显异常。此外,与对照组比较BPPV组ENG中温度试验和DPG的前庭评分明显异常(P<0.05),并且≥12个月患者上述检查异常程度更高(P<0.05)。结论:ENG与DPG是重要的前庭功能检查方法,二者联合应用能够全面分析BPPV患者前庭功能病变,且BPPV患者病程直接影响其前庭功能。Objective：To detect the significance of the electronystagmography（ENG） and the dynamic posturography（DPG） in the vestibular function examination in patients suffering BPPV.Method：Forty,34 to 79 old vertigo patients were examined with DPG and ENG.DPG evaluation parameters includes sense organization test from vestibular sensory score,proprioception score,visual score,Romber＇s score and composite score.ENG examination include caloric test.Result：Twenty-six out of 40 BPPV patients got abnormal caloric test results;33 patients got DPG abnormality which led to a low vestibular perception scores.Twenty-four out of these patients got abnormal results in both caloric test and DPG,while in 9 patients that got normal caloric results came up with low vestibular perception scores,except for which there was no significant abnormality in SOT.Besides,the BPPV patients,compared with normal,got abnormal scores in caloric test of ENG and vestibular perception test of DPG（P0.05）,if course of BPPV was over 12 months,higher abnormal degrees appeared（P0.05）.Conclusion：ENG and DPG are important methods in vestibular function tests,a comprehensive analysis of both is applied to value the severity of vestibular function in patients with BPPV and the duration of BPPV directly affects the vestibular function.
