Abstract

Objective: We sought to assess prognostic factors associated with initial successful treatment and recurrence of benign paroxysmal positional vertigo (BPPV) with the canalith repositioning (CRP) maneuver with mastoid vibration.

Methods: We conducted a retrospective chart review of 104 consecutive BPPV patients at a tertiary care referral center during 1999. Methods: The main outcome measures were resolution of BPPV and absence of nystagmus on Hallpike maneuver.

Results: Ninety-three patients (89.4%) experienced initial symptom resolution, and 21 of the initially successful patients had a recurrence (recurrence rate of 22.6%). Prior trauma or labyrinthitis was found to predict the lowest initial CRP success. Endolymphatic hydrops and central nervous system-related dizziness as cofactors with BPPV were associated with the highest recurrence rates.

Conclusions: Specific concurrent otologic conditions are associated with different outcomes in BPPV.
