Predictive Factors of Bell’s Palsy: Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio

Abstract Objectives: Inflammation plays an important role in the pathogenesis of Bell’s palsy. Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are indicators of inflammation. The aim of this study was to find the prevalence of Bell's palsy and the mean of neutrophil to lymphocyte ratio and platelet to lymphocyte ratio among them. Result: Out of all patients who visited ENT outpatient department during the study period, the overall prevalence of Bell’s palsy was 0.6% (117) at a 95% confidence interval (0.5-0.72%). Among them, the mean neutrophil to lymphocyte ratio was 5.014±1.63, and the mean platelet to lymphocyte ratio was 207.38±54.59.Both NLR and PLR values were raised in Bell’s palsy. Therefore, NLR and PLR can be used as auxiliary param­eters in the management of Bell’s palsy.
