ABSTRACT

Bell’s palsy is a type of idiopathic facial paralysis that is caused by various virulence factors and results in a poor prognosis. This spontaneous facial paralysis that has various causes should be accurately diagnosed in clinical settings at an early stage, and one of the methods used at this stage is electroneuronography (ENoG). The ENoG test analyzes and quantitatively evaluates the degeneration of the facial muscles. The progression and improvement of the disease are measured using the results of the ENoG. This study was conducted among 185 Bell’s palsy patients who were enrolled at D hospital in Korea, and the diagnostic utility of their ENoG results were analyzed using regression and ROC curve analysis methods.

Keywords: Bell’ palsy, Facial nerve palsy, Electroneuronography(ENoG), ROC curve.
