BACKGROUND: Vestibular dysfunction is prevalent in severe/profound unilateral idiopathic sudden sensorineural hearing loss (ISSNHL) and may influence hearing recovery. This study investigates associations between vestibular function (cVEMP/oVEMP, vHIT, caloric tests) and short-term auditory outcomes.
AIMS: To evaluate whether vestibular test abnormalities predict treatment response in severe/profound ISSNHL and identify independent prognostic factors.
MATERIAL AND METHODS: Retrospective analysis of 133 patients (mean age 53.58 ± 18.56 years) treated with steroids/hyperbaric oxygen. Vestibular tests (cVEMP, oVEMP, vHIT, caloric) were performed pre-treatment. Outcomes were categorized as effective (complete/marked recovery) or ineffective (mild/no recovery).
RESULTS: The ineffective group had higher vertigo prevalence (65/93 vs 14/40, p < 0.001) and older age (55.98 ± 17.85 vs 48.00 ± 19.22 years, p = 0.022). Univariate analysis showed abnormal vestibular tests (oVEMP/cVEMP/vHIT/caloric) correlated with outcomes (p < 0.05). Multivariate analysis identified three independent predictors of poor outcome: vertigo (OR 0.367), abnormal caloric test (OR 0.339), and abnormal vHIT (OR 0.316). cVEMP/oVEMP abnormalities were not independently associated (p > 0.05).
CONCLUSIONS: Vertigo, abnormal caloric/vHIT results predict poorer short-term hearing recovery in severe/profound ISSNHL. Vestibular assessment aids prognosis but should not be used alone. Larger studies are needed for validation.
