    Abstract:
    Objective:To study the clinical features of patients with recurrent benign paroxysmal positional vertigo (BPPV) and to analyze potential related factors of recurrences.Method:Eighty patients who suffered recurrent BPPV were enrolled in this study. Patients were divided into three groups: young group (21 cases), middle-aged group (25 cases) and old-aged group (34 cases). Theclinical data including age, gender, pathological pattern and canal type of BPPV were collected. We further analyzed the efficacy of repositioning treatment for recurrent BPPV.Result:In this study, there are 62 cases of primary BPPV(77.50%) and 18 cases of secondary BPPV(22.50%). In patients with recurrent BPPV, the laterior semicircular canal BPPV and posterior semicircular canals BPPV were the most common, and there was no differences on the aspects of age and gender in the two groups of patients with recurrent HSC BPPV and PSC BPPV (P>0.05).Compared with the primary diagnosis, we found that 48.75% cases relapsed in the same semicircular canals, 21.25% cases relapsed in other canals of the same ear, and 30.00% cases relapsed in a different ear. In this study, 96.25% patients with recurrent BPPV were cured in a month and one-time reset success rate was 56.25%.Conclusion: The age, gender, pathological pattern and canal type show certain clinical features of recurrent BPPV. The evidence of long term of recurrence course and high variability of problematic location support the approval opinion based on new otolith.
