Abstract

OBJECTIVE

To explore the etiological factors of benign paroxysmal positional vertigo (BP-PV).

METHODS

The clinical data of 145 patients with BPPV were retrospectively reviewed. The impacts of gender and age on BPPV were analyzed. The relationship between the onset of BPPV and the internal ear ischemia was also explored.

RESULTS

The abnormality rate of auditory brainstem response (ABR) under high stimulus rate was 59.3% (86/145) in all the patients with, including 22.1% (32/145) in male and 37.2% (54/ 145) in female (P > 0.05). The abnormality rate of ABR under high stimulus rate were 37.9% (55/145) and 21.4% (31/145) in middle-aged (30-55 years) and old ( > 55 years) patients, respectively (P > 0.05).

CONCLUSION

The onset of BPPV may relate to ischemic internal ear but is not relevant with gender and age.

摘要

目的

探讨良性阵发性位置性眩晕（BP-PV）的病因。

方法

回顾性分析145例BPPV患者的临床资料。分析性别和年龄对BPPV的影响。同时探讨BPPV发作与内耳缺血之间的关系。

结果

所有患者中，高刺激率下听性脑干反应（ABR）异常率为59.3%（86/145），其中男性为22.1%（32/145），女性为37.2%（54/145）（P>0.05）。中年（30 - 55岁）和老年（>55岁）患者高刺激率下ABR异常率分别为37.9%（55/145）和21.4%（31/145）（P>0.05）。
