Outcomes of Treatment of Multicanal Benign Paroxysmal Positional Vertigo by Means of TRV Chair

Introduction: Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of peripheral vertigo and can manifest in different forms. Multicanal BPPV is rare and difficult to treat. TRV Chair is a method that offers diagnosis and treatment at the same time. The aim was to analyze the outcomes of treatment of multicanal BPPV by means of TRV Chair and compare those results with manual maneuvers. Methods: Forty-nine subjects aged 26-73 and diagnosed with multicanal BPPV were included. Appropriate maneuvers were performed on affected canals either by TRV Chair or manually. The number of maneuvers required by TRV Chair and manual maneuver were analyzed and compared. Results: The mean number of maneuvers performed until the treatment was completed in manual treatment group was 2.57 ± 1.03, and in TRV group, it was 2.25 ± 1.16. No significant difference was observed between the number of maneuvers performed in either group until the end of the treatment (p > 0.05). Discussion/Conclusions: Neither TRV Chair nor manual maneuvers were superior to the other in the treatment of multicanal BPPV cases.
