OBJECTIVE: To evaluate the presence of cardiovascular risk factors and recovery of idiopathic sudden sensorineural hearing loss in hospitalised patients. METHODS: A single-centre retrospective study of 80 patients hospitalised for idiopathic sudden sensorineural hearing loss was conducted over a 6-year period. Mean pure tone hearing thresholds were assessed by pure tone audiometry. RESULTS: Twenty-three of 80 patients (28.75 per cent) initially had no cardiovascular risk factors. Forty-five patients had hyperlipidaemia, 22 patients had hypertension, 7 patients had diabetes mellitus and 7 patients were obese. No statistically significant difference was observed between patients with complete versus partial sudden sensorineural hearing loss (p = 0.0708) concerning the cardiovascular risk factors. At long-term follow up, the hearing recovery rate was not significantly different between the two groups of patients (p = 0.7541). CONCLUSION: The lack of a clear relationship between idiopathic sudden sensorineural hearing loss and cardiovascular risk factors suggests that sudden sensorineural hearing loss has a predominantly multifactorial disease profile regardless of hearing impairment severity.
