We assessed the efficacy ofthe Epley maneuver (canalith repositioning) in a study of 81 patients with posterior semicircular canal benign paroxysmal positional vertigo (BPPV). A group of61 patients underwent the maneuver; while a control group of20 patients received no therapy. All patients were evaluated at 1and 6 months. Thep ercentage ofpatients who experienced subj ective improvement was significantly high er in the treatment group at both 1 month (89% vs. 10%) and 6 months (92% vs. 50%). Three patients in the treatment group who did not improve after treatment underwent a second maneuver; and all achieved a po sitive result. In addition , 4 successf ully treated pati ents exp erienced a recurrence between 1 and 6 months following treatment; 3 were retreated, and 2 of them respondedwell. We conclude that the Epley maneuver provides effective and long-term control ofsymptoms in p atients with BPPV.
