| Popis: | ObjectivesThe prognostic significance of vertigo in patients with idiopathic sudden sensorineural hearing loss (SSNHL) remains a matter of debate because vertigo is associated with many different vestibular disorders. The purpose of this study is to determine the role of benign paroxysmal positional vertigo (BPPV) as a prognostic factor in patients with SSNHL.MethodsWe conducted a retrospective study of 298 patients with SSNHL. Hearing outcomes were evaluated by assessments of pre-treatment hearing and hearing gain. Comparative multivariate analyses between prognostic factors and hearing outcome were conducted.ResultsThirty-eight (12.7%) SSNHL patients were found to also have BPPV. BPPV showed significant negative prognostic factors in hearing outcome on multivariate analysis (odds ratio, 0.15). In comparison to average pure tone audiometry (PTA), patients diagnosed with SSNHL with BPPV exhibited poorer hearing in pre- and post-treatment PTA compared to SSNHL without BPPV. Old age (>60 years), pre-treatment hearing, and canal paresis were significant outcome predictors.ConclusionBPPV in SSNHL patients, representing definitive vestibular damage, was closely related to poor prognosis. |
