A Study of Facial Nerve Palsy Cases Using Electroneurography

Abstract

We investigated the association between electroneurography（ENoG） values and time to cure in 22 patients undergoing ENoG who could be followed up to determine the prognosis of peripheral facial palsy in our department between January 2021 and March 2024. In addition, we evaluated the effect of the presence or absence of ear pain, stapedial reflex, concomitant hypertension, and concomitant diabetes mellitus at the initial examination on ENoG values and time to cure. No statistically significant differences were observed in the association between mean ENoG values（%）and mean time to cure（days） regardless of the presence or absence of ear pain, stapedial reflex, concomitant hypertension, and concomitant diabetes mellitus. The correlation coefficient for the association between ENoG values and time to cure was -0.47197, showing a relatively strong negative correlation. This study shows that patients with an ENoG value of ≥20% recover approximately 2 months after onset of peripheral facial palsy.
