Horizontal canal benign paroxysmal positional vertigo (HC-BPPV) can be classified as either the geotropic or apogeotropic subtype by the pattern of nystagmus triggered by supine head roll test. Most studies have reported the geotropic subtype as a more common pathophysiology in HC-BPPV than the apogeotropic subtype. According to the BPPV clinical practice guideline provided by the American Academy of Otolaryngology-Head and Neck Surgery and American Academy of Neurology in 2008, variations of the roll maneuver (Lempert maneuver of barbecue roll maneuver) are the most widely published treatments for HC-BPPV. In addition, various treatment techniques including Gufoni maneuver, Vannuchi-Asprella liberatory maneuver and forced prolonged positioning have been applied for HC-BPPV. However, the guideline failed to provide specific treatment guidelines for HC-BPPV based on evidence-based researches since only Class IV data on HC-BPPV treatment were available at the point of 2008 when the BPPV clinical practice guideline was published. This review article focused on the evidences of the efficacy of various maneuvers in the treatment of HC-BPPV published after the BPPV clinical practice guidelines of 2008.
