Immediate efficacy of Gufoni maneuver for horizontal canal benign paroxysmal positional vertigo (HC-BPPV): a meta-analysis

Abstract Objective This meta-analysis aims to systematically measure the immediate efficacy of the Gufoni maneuver for horizontal canal benign paroxysmal positional vertigo (HC-BPPV). Methods A extensive search electronic databases, including PubMed, Embase, Web of Science and Cochrane library, were searched until to September 1, 2018 for relevant articles. We selected only randomized clinical trials studying with treatment of HC-BPPV employ by the Gufoni maneuver. Results Five randomized clinical trials were included in the current meta-analysis with a total of 714 HC-BPPV patients. The meta-analysis revealed that Gufoni maneuver had a higher immediate recovery rate than sham maneuver in treatment of HC-BPPV (risk ratio = 2.68, 95% CI, 1.54–4.65, p Conclusion Gufoni maneuver has a satisfactory immediate efficacy for HC-BPPV and does not increase otolith switch rate.
