title: Epley and Semont maneuvers for posterior canal benign paroxysmal positional vertigo: A network meta-analysis.
abstract: OBJECTIVE
  Using network meta-analysis, we aimed to compare the efficacy and safety of Epley and Semont maneuvers as treatment options for posterior canal benign paroxysmal positional vertigo.
  
  
  METHODS
  Network meta-analysis.
  
  
  METHODS
  Randomized controlled studies with a Jadad score ≥ 3 that used an Epley or Semont maneuver in posterior canal benign paroxysmal positional vertigo patients were analyzed in this project. The following efficacy outcomes included 1-week recovery rate and end of study recovery rate. Recurrence rate was used to assess the safety of each treatment.
  
  
  RESULTS
  Of 589 articles, 12 studies that enrolled 999 posterior canal benign paroxysmal positional vertigo patients were selected. The pooled analysis revealed that the Epley maneuver was as efficacious as the Semont maneuver, in both the 1-week recovery rate and end of study recovery rate (odds ratio [OR] = 1.8, 95% confidence interval [CI] = 0.48-7.00; OR = 1.8, 95% CI = 0.47-7.20), and had a similar recurrence rate (OR = 1.00, 95% CI = 0.33-4.4). These two techniques were both better than sham-controlled treatment in the two efficacy indicators. No difference was observed in recurrence rate for treatments.
  
  
  CONCLUSIONS
  The Epley maneuver was similar to the Semont maneuver in both efficacy and safety for posterior canal benign paroxysmal positional vertigo in short-term effects, and both were superior to the sham-controlled treatment.
