| Popis: | Objective To study the relationship between various electrodiagnostic modalities in acute facial palsy. Setting Academic tertiary care center. Patients One‐hundred and six patients who presented with traumatic or non‐traumatic acute facial paralysis (House‐Brackmann, HB, grade 6/6) between 2008 and 2017 and underwent acute electrodiagnostic testing. Intervention Electroneurography (ENoG) using nasolabial fold (NLF) or nasalis muscle (NM) methods, and volitional electromyography (EMG) in all patients. Main outcome measures Percent degeneration of ipsilateral facial nerve compound muscle action potentials (CMAP) on NLF‐ and NM‐ENoG, presence or absence of muscle unit potentials (MUPs) on EMG. Results Extent of facial nerve degeneration measured by NLF‐ and NM‐ENoG were highly correlated (r = 0.85, P This is an original study that defines outcomes for electrodiagnostic testing in acute facial palsy and compares two methods. Electrodiagnostic testing is often used by clinicians to prognosticate outcomes for patients with acute facial palsy and determine candidacy for facial nerve decompression. This study describes one of the largest cohorts of patients to date with acute facial paralysis (House‐Brackmann 6/6) and detailed electrodiagnostic testing, consisting of two methods of electroneurography (ENoG) and electromyography (EMG). |
