Abstract
We assessed the efficacy of the Epley maneuver (canalith repositioning) in a study of 81 patients with posterior semicircular canal benign paroxysmal positional vertigo (BPPV). A group of 61 patients underwent the maneuver, while a control group of 20 patients received no therapy. All patients were evaluated at 1 and 6 months. The percentage of patients who experienced subjective improvement was significantly higher 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 positive result. In addition, 4 successfully treated patients experienced a recurrence between 1 and 6 months following treatment; 3 were retreated, and 2 of them responded well. We conclude that the Epley maneuver provides effective and long-term control of symptoms in patients with BPPV.

Abstract
To investigate whether migraine is more common in patients with benign paroxysmal positional vertigo (BPPV) than in the general population, the author conducted a retrospective study of 476 patients with BPPV seen over 12 years at a tertiary referral center. Records of patients with a confirmed diagnosis of BPPV followed for 1 to 7 years were reviewed. The typical history of BPPV and the characteristic torsional positional nystagmus were identified in all patients. A modified Epley maneuver was performed for all patients with posterior semicircular canal BPPV, with a 98% success rate. The survey consisted of detailed patient questionnaires and vestibular tests. Migraine and motion sickness were three times more common in patients with BPPV than in the general population. A family history of migraine (58.4%) and vertigo (44.9%) was also more common in patients than in a control group.
