Treatment of horizontal canal BPPV: Pathophysiology, available maneuvers, and recommended treatment

Objectives/HypothesisTo describe the pathophysiology of horizontal canal benign paroxysmal positional vertigo, the available maneuvers for its management, and the recommended treatment. Data SourcesPubMed, Cochrane library. Review MethodsReview of the available literature. ResultsTwo theories of pathophysiology underlying the disease are described, along with available maneuvers reflecting those theories; and videos of the maneuvers are provided. A comparison of available treatments is made. ConclusionA variety of maneuvers is available related to the pathophysiology underlying the disease. The treatment chosen should be appropriate to the patients' ages, general conditions, and other diseases they may have. No treatment was found to be superior over the others regarding the success rate. In the case of geotropic nystagmus, the Gufoni maneuver is superior in its ease of performance. When it comes to apogeotropic nystagmus, the Barbecue and Gufoni maneuvers have comparable success rates. Laryngoscope, 125:1959-1964, 2015
