title: Management of bilateral benign paroxysmal positional vertigo.
abstract: OBJECTIVE
  To describe a series of patients with bilateral benign paroxysmal positional vertigo (BiBPPV), with respect to demographics, management, and outcome.
  
  
  METHODS
  All patients who were identified and treated for BiBPPV in a previous 36-month period with a minimal follow-up period of 6 months were included. Patients were treated with Epley's maneuver (EM) on the side that was more symptomatic and that had a greater velocity and amplitude of tortional nystagmus. Patients were re-treated according to symptoms and findings on follow-up visits.
  
  
  RESULTS
  Ten patients were identified with BiBPPV. Most patients complained of nonlocalized positional vertigo and unsteadiness. Four were males and 6 were females, and the mean age was 54 years. There was a positive history of recent head trauma in 4 of the patients. All patients recovered after performing a mean of 2.6 EMs during a 3-month period. One patient experienced unilateral recurrence and was re-treated successfully.
  
  
  CONCLUSIONS
  BiBPPV has typical characteristics and can be managed successfully with EM, performed on the more symptomatic side, followed by repeated treatments as needed.
