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

Abstract

Bell's palsy (BP) is the most frequent cause of unilateral facial paralysis at a rate of 60-75% (1). It may appear in all stages of life, most often heals completely and may recur with various severity in 15% of patients (2,3). The pathogenesis of BP is not clear; however, inflammation and viral infections are thought to play an important role (4). As a result of inflammation, edema occurs in the fallopian tubes, especially in the labyrinth segment (5).
