Abstract

Several benign paroxysmal positional vertigo (BPPV) treatments, including Particle Repositioning Maneuver (PRM) and Liberatory Maneuver (LM), are based on the "canalolithiasis" theory, and the usefulness of these treatments has been confirmed. We examined whether the accuracy of prognosis can be improved by checking the direction of nystagmus during treatment (secondary nystagmus). When secondary nystagmus occurred in the same direction as the provoked initial position, the efficacy of treatment was 90.9%. When secondary nystagmus was reversed, the efficacy was 30.8%. When there was no nystagmus appearing after the initial position, all cases improved. These results support the canalolithiasis theory and the spontaneous improvement rate seems to be about 30%. It is thus important to check secondary nystagmus to predict the prognosis of the BPPV after positioning treatment.
