- Abstract
- Background and Objectives
Benign paroxysmal positional vertigo (BPPV) is treated with appropriate canalith repositioning procedures, which are very effective for the treatment of BPPV. Nevertheless, the recurrence of BPPV may occur after the initial successful treatment. The purpose of this study was to investigate the risk factors and clinical features of recurrent BPPV.
Subjects and Method
The retrospective study was performed for 227 patients who were diagnosed with BPPV and treated with appropriate canalith repositioning procedures from March 2013 to December 2014. We analyzed various clinical characteristics, locations and types of canalith for the whole BPPV patients, and the interval and frequency of recurrence in the patients of recurrent BPPV.
Results
Of the total of 227 BPPV patients, 47 patients were recurrent BPPV (21%). The patients of recurrent BPPV were significantly older than those of non-recurrent BPPV (p=0.034). BPPV patients recurred more with increased age, with the significantly increased frequency of recurrence (p=0.010). Twenty two patients were posterior semicircular canal canalolithiasis (PSCC) (46.8%) and 25 patients were lateral semicircular canal canalolithiasis (LSCC) (53.2%). The number of canalith repositioning procedures was significantly higher in LSCC patients than in PSCC patients (p=0.041). The location change of affected canal were identified for 23 patients and the type change of LSCC to ipsilateral PSCC was the most common.
Conclusion
Age is an important prognostic factor to be considered in BPPV recurrence. Also, the affected semicircular canals were frequently changed in the recurrent BPPV.
