Overview

Retrospective cohort study investigates clinical factors predicting electroneurography results in early-stage Bell’s palsy, suggesting clinical implications.

Key Points

  • This study examines the relationship between neutrophil-to-lymphocyte ratio (NLR) and initial facial weakness with electroneurography results in early-stage Bell's palsy.
  • Retrospective cohort study of 97 adults with early-stage Bell's palsy diagnosed from January 2014 to September 2021.
  • Reviewed medical records including NLR and House-Brackmann grades.
  • Utilized electroneurography to measure axonal loss via compound muscle action potential (CMAP) amplitude ratio.
  • An initial House-Brackmann grade II–III was associated with good ENoG results (OR, 4.79; 95% CI, 1.39–16.46).
  • An NLR < 1.92 indicated good ENoG results (OR, 5.54; 95% CI, 1.85–16.53).
  • Classification and regression tree (CART) model predicted axonal loss with 87.5% sensitivity and 85.6% accuracy.
