Particle Repositioning Maneuver Versus Brandt-Daroff Exercise for Treatment of Unilateral Idiopathic BPPV of the Posterior Semicircular Canal

PRM is more effective treatment and as safe as B-D exercise in the short term for unilateral and idiopathic PC-BPPV, and although it does not reduce the probability of recurrence in the 4-year follow-up period compared with B-D exercise, it may delay the second recurrence's onset in those patients who had already experienced a single recurrence. Our study supports the use of PRM as the treatment of choice in unilateral and idiopathic PC-BPPV, although exercise may be also considered as an alternative treatment in selected cases.
