Enhancing Prognosis in Bell Palsy: Electrodiagnostic Testing Beyond House-Brackmann Grade
Highlight
This study investigates the incremental prognostic value of electrodiagnostic testing in Bell palsy beyond the traditional House-Brackmann (H-B) grading system, focusing especially on patients with moderate paralysis (H-B grade IV). Key findings include strong associations of electroneuronography degeneration index (ENoG DI) ≥90% and complete denervation on electromyography with poorer 6-month recovery, and improved model discrimination for incomplete recovery when electrodiagnostic results are combined with initial clinical grading.
