Abstract excerpt
Sudden sensorineural hearing loss (SSNHL) is an idiopathic condition lacking reliable biomarkers or established causal mechanisms. While systemic metabolic dysregulation has been implicated, the specific role of central nervous system metabolites remains unexplored. We applied a 2-sample Mendelian randomization framework to evaluate the causal influence of cerebrospinal fluid (CSF) metabolites on SSNHL risk....
