Objectives: Although bilateral involvement in benign paroxysmal positional vertigo (BiBPPV) is not uncommon, there has only been one previous comprehensive report on a cadre of patients with this entity. This study, prospectively evaluated patient with BiBPPV, with respect to demographics, management, and outcome.
Methods: All patients identified and treated for BiBPPV in a previous 22-month period were included. They were followed up in a tertiary neurotology outpatient clinic. All patients were treated with Epley's maneuver on the side that was more symptomatic at the time of initial presentation and had a greater velocity and amplitude of rotatory nystagmus. Patients were retreated according to symptoms and findings on follow-up visits.
Results: During a period of 22 months, 145 patients were diagnosed with BPPV. Ten of the patients were identified with BiBPPV, with a minimal follow-up period of 6 months. Most patients complained of nonlocalized positional vertigo and unsteadiness. Four were males and 6 were females, and the mean age was 52. There was a positive history of recent head trauma in 5 of the patients. All patients were cured after performing a mean of 3 Epley's maneuvers over a 3-month period.
Conclusions: BiBPPV has typical charisteristics and can be managed sucsessfully with Epley's maneuver performed on the more symtomatic side, followed by repeated treatments, as needed.
