Treatment Efficacy of Various Maneuvers for Lateral Canal Benign Paroxysmal Positional Vertigo With Apogeotropic Nystagmus: A Randomized Controlled Trial

Abstract

Objectives: To investigate the most effective treatment method by comparing the effects of various otolith reduction techniques in patients with apogeotropic lateral semicircular benign paroxysmal positional vertigo (LC-BPPV).Methods: We performed a multicenter, randomized prospective study between January and December 2015 on 72 consecutive patients with apogeotropic LC-BPPV. The treatment group was divided into three groups: therapeutic head-shaking (THS, Group A), Gufoni-Appiani maneuver (Group B), and cupulolith repositioning maneuver (CuRM) (Group C). Each treatment group was evaluated and treated until the 4th week.
