Purpose: To evaluate positioning vertigo and nystagmus evolution after one or more Epley’s maneuvers in patients suffering from benign paroxysmal positional vertigo (BPPV) associated with Menière’s disease. Method: Files from patients with BPPV associated with Menière’s disease were analyzed to collect information regarding to the number of Epley’s maneuvers necessary to eliminate positioning nystagmus and the symptoms evolution during 12 months after the positioning nystagmus elimination. Results: Sixty-two patients with posterior semicircular canal BPPV and definite diagnosis of Menière’s disease were included in this study. It was necessary one Epley’s maneuver to eliminate positioning nystagmus in 80.7% of the patients, two in 16.1%, and three in 3.2%; with the nystagmus elimination, positioning vertigo was suppressed in 71.0% of the patients, improved in 27.4% and remained unaltered in 1.6%. Four weeks after the elimination of the positioning nystagmus, all patients were asymptomatic. On a follow-up in 12 months time, BPPV recurrence affecting posterior, lateral or anterior canals was verified in 19.4% of the cases. The specific maneuver for the involved semicircular canal abolished the positioning vertigo and nystagmus in all of these cases. Conclusions: After performing one, two or three Epley’s maneuvers in patients with BPPV associated with Menière’s disease, it was observed: 1) elimination of positioning nystagmus; 2) elimination of positioning vertigo in until four weeks time after the elimination of positioning nystagmus, and 3) cases with BPPV recurrence in a 12 months time follow-up, with elimination of positioning vertigo and nystagmus by means of one specific maneuver for the affected semicircular canal.
