| Laryngeal electromyography showed a 20 to 30% decreased recruitment in the distribution of the right superior laryngeal nerve. Laryngeal electromyography demonstrated mild paresis of the right superior laryngeal nerve. 1) Differentiation of these etiologies is based on the history and findings on flexible laryngoscopy, direct laryngoscopy (with arytenoid palpation), and laryngeal electromyography (EMG). |
