Treatment of Benign Paroxysmal Positional Vertigo with the TRV Reposition Chair

OBJECTIVES The primary objective of this study was to evaluate how successful the reposition of retractable benign paroxysmal positional vertigo (BPPV) was when treating patients with the Thomas Richard Vitton (TRV) reposition chair. MATERIALS AND METHODS This is a prospective clinical trial. A total of 81 BPPV patients who were referred to the tertiary Balance - Dizziness Centre at the Department of Otolaryngology, Head - Neck Surgery and Audiology, Aalborg University Hospital, Denmark were included and analyzed. All the patients were diagnosed and treated with the TRV reposition chair. RESULTS The patients were successfully treated after an average of 2.23 (± 1.66 SD) treatments with the TRV reposition chair. There was a significant difference between the number of treatments needed in the single semicircular canal group and the multicanal group. Seventeen (22.6%) of the patients experienced either dislocation of otoconia, relapse, or new onset of BPPV during the trial period. The number of patients with BPPV located to the anterior, lateral, and multiple semicircular canals in this study was significantly higher than that in similar studies. Six patients (7.4%) were classified as treatment failures. CONCLUSION We found the TRV reposition chair to be very successful in the diagnostics and treatment of patients with retractable and atypical BPPV. However, 7.4% experienced treatment failure.
