AbstractWe assessed the efficacy of Epley maneuver in patients with posterior canal benign paroxysmal positional vertigo (P-BPPV) and Lempert maneuver in patients with horizontal canal BPPV (H-BPPV). In patients with P-BPPV, positional vertigo in patients treated by Epley maneuver was significantly resolved more quickly than that in untreated patients. But in patients with H-BPPV, there were no significant differences of time course in remission of positional vertigo between untreated patients and patients treated by Lempert maneuver. Among the untreated patients, the positional vertigo in patients with H-BPPV was significantly resolved more quickly than that in patients with P-BPPV. Epley maneuver was effective for the treatment of patients with P-BPPV, whereas the efficacy of Lempert maneuver for the treatment of patients with H-BPPV was limited. The natural courses in remission of positional vertigo in untreated patients with H-BPPV showed significantly faster resolution than that in patients with P-BPPV.
