    Abstract:
    BACKGROUND: To evaluate the efficacy of Epley's maneuver plus betahistine in the management of patients with posterior canal benign paroxysmal positional vertigo (PC-BPPV). METHODS: Electronic databases including PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, and Wanfang were searched from their inception to April, 2022. The effect size was analyzed by calculating the pooled risk ratio estimates of efficacy rate, recurrence rate, and standardized mean differences (SMD) of dizziness handicap inventory (DHI) score with a 95% confidence interval (CI). Sensitive analysis was performed simultaneously. RESULTS: A total of 9 randomized controlled trials with 860 PC-BPPV patients were included in the meta-analysis, in which 432 were treated with Epley's maneuver plus betahistine, and 428 received Epley's maneuver alone. The meta-analysis revealed that Epley's maneuver plus betahistine significantly improved DHI score than Epley's maneuver alone (SMD = -0.61, 95% CI -0.96 to -0.26, P = .001). In addition, both Epley's maneuver plus betahistine and Epley's maneuver groups had comparable outcomes in efficacy rate and recurrence rate. CONCLUSION: This meta-analysis shows that Epley's maneuver plus betahistine in PC-BPPV patients had favorable effects on DHI score.
