Abstract
Introduction
Sudden sensorineural hearing loss (SSHL) is an otologic urgency whose treatment is still controversial. Its etiology remains largely unknown in most cases and predicting its prognosis is still a challenge. Cardiovascular risk factors (CVRF) have been implicated in the etiopathogenesis of this entity.
Objectives
Application of the SCORE (Systematic Coronary Risk Evaluation) risk scale in patients with SSHL and evaluation of its potential prognostic value in recovery in patients with CVRF.
Materials and methods
Prospective analysis of patients with SSHL admitted for protocol treatment including intravenous corticosteroid therapy associated to weekly intratympanic injection in the event of therapeutic failure or severe hearing loss at admission. Demographic, audiometric, clinical and imaging data were assessed. The SCORE risk scale was applied and the audiometric recovery was compared among different risk groups.
Results
Our overall complete and partial recovery rates were 35.9% and 26%, respectively. More than a half of our patients had at least one CVRF. Of these, overweight/obesity, hyperlipidemia and hypertension were the most common. In our sample, patients with CVRF and higher SCORE risk presented higher PTA at admission and also worse hearing outcome, although these results were not statically significant.
Conclusion
This preliminary study could not confirm the validity for SCORE scale for cardiovascular risk assessment in predicting audiometric recovery in patients with SSHL with multiple comorbidities. Further research with larger samples are needed to elucidate the etiology of SSHL and the exact role of cardiovascular risk factors in the pathophysiology of SSHL.
