Diagnostic value of repeated Dix-Hallpike and roll maneuvers in benign paroxysmal positional vertigo [Valor diagnóstico da repetição das manobras de Dix-Hallpike e roll-test na vertigem posicional paroxística benigna]

Introduction Benign Paroxysmal Positional Vertigo (BPPV) is the most common peripheral vestibular disorder. The Dix-Hallpike and Roll maneuvers are used to diagnose BPPV. Objective This study aims to investigate the diagnostic value of repeated Dix-Hallpike and Roll maneuvers in BPPV. Methods We performed Dix-Hallpike and roll maneuvers in patients who admitted with peripheral vertigo anamnesis and met our criteria. The present study consists of 207 patients ranging in age from 16 to 70 (52.67 ± 10.67). We conducted the same maneuvers sequentially one more time in patients with negative results. We detected patients who had negative results in first maneuver and later developed symptom and nystagmus. We evaluated post-treatment success and patient satisfaction by performing Dizziness Handicap Inventory (DHI) at first admittance and two weeks after treatment in all patients with BPPV. Results Of a total of 207 patients, we diagnosed 139 in first maneuver. We diagnosed 28 more patients in sequentially performed maneuvers. The remaining 40 patients were referred to imaging. There was a significant difference between pre- and post-treatment DHI scores in patients with BPPV (p < 0.001). Conclusion Performing the diagnostic maneuvers only one more time in vertigo patients in the first clinical evaluation increases the diagnosis success in BPPV. Canalith repositioning maneuvers are effective and satisfactory treatment methods in BPPV. © 2016 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facia
