Magnetic Laryngeal Reanimation as a Novel Treatment of Vocal Fold Immobility

摘要

Objective. Vocal fold paralysis may result from surgical complications, trauma, tumor, or unknown causes. When both cords are affected, paramedian fixation can lead to life-threatening obstruction. Current treatments, including tracheostomy, cordotomy, and arytenoidectomy, compromise speech and swallow function to maintain a safe airway. To preserve all three critical laryngeal functions, Otolaryngologists need a solution for bilateral vocal fold paralysis that restores motion. This study uses implantable electromagnet technology to create dynamic vocal fold movement in a proof-of-concept, preliminary model.
