[Pathogenesis of benign paroxysmal positional vertigo].
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).


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