title: Clinical analysis of patients with idiopathic sudden sensorineural hearing loss and benign paroxysmal positional vertigo.
abstract: CONCLUSIONS
  Thirteen (5.4%) of patients with idiopathic sudden sensorineural hearing loss (ISSNHL) had benign paroxysmal positional vertigo (BPPV). Most of the patients showed profound hearing loss and had BPPV of the lateral canal. BPPV in patients with ISSNHL may have no influence on hearing recovery.
  
  
  OBJECTIVE
  BPPV occurs in 8.6-12.7% of patients with ISSNHL; however, the role of BPPV in hearing recovery remains controversial. Therefore, we investigated hearing outcomes in the patients, including the distribution of initial hearing threshold, the type of canal involved, and the number of repositioning maneuvers performed.
  
  
  METHODS
  Of 241 patients with ISSNHL who presented to a dizziness clinic between March 2008 and May 2012, 13 with both ISSNHL and BPPV were recruited for this study. The patients were evaluated for their initial hearing threshold, type of canal involved, response to repositioning maneuvers, and hearing outcome. Age- and hearing threshold-matched patients with ISSNHL but without BPPV were randomly sampled and included for a hearing outcome comparison.
  
  
  RESULTS
  Of 13 patients with ISSNHL and BPPV, 11 showed profound hearing loss. The lateral canal was involved in 11 patients, including 3 who had multi-canal involvement. Ten patients underwent a single repositioning maneuver. Those patients did not display a significant difference in hearing recovery compared with those patients having ISSNHL only.
