Abstract

BACKGROUND AND OBJECTIVES
Benign paroxysmal positional vertigo (BPPV) has been well controlled with otolith reposition maneuver. The purpose of this study was to investigate the incidence of various forms of BPPVs such as type change during the reposition maneuver, combined type and recurred cases, to study the therapeutic result of physical therapy in various forms of BPPVs, and to figure out the therapeutic strategy. MATERIALS AND METHOD: One hundred and twenty-seven patients who were diagnosed with BPPV were included in this study. Reposition maneuver was performed once a day until nystagmus disappeared. In the case of posterior canal BPPV, Epley maneuver was performed. In the case of lateral canal BPPV, barbecue rotation maneuver was performed in canalolithiasis type, and cupulolith reposition maneuver in cupulolithiasis type. In each type of BPPV, we analyzed the number of treatment, recurrence, changing type, and the relationship between recurrence and age or sex of patients. RESULTS: Posterior canal origin was more common than lateral canal origin. All cases except 2 were recovered by reposition maneuver. In 8 cases, the type of disease was changed, and the treatment of these cases were changed according to new type and origin. Overall recurrence rate was 14%, and they were completely treated with reposition maneuver. There was no correlation between recurrence and origin, type, age or sex of patients. CONCLUSION: Patients showed various origin, type and recurrence. Type of the disease was possibly changeable. Almost all the cases were cured with suitable reposition maneuver. Recurrence rate was relatively high, and the close follow up is required.
