Abstract

Vocal fold immobility (VFI) is a common cause of dysphonia and dysphagia in children. Laryngeal electromyography (LEMG) is an important adjunctive test in its diagnosis and treatment. In this study, we present an alternative technique in which bipolar double hookwire electrodes allow simultaneous placement and recordings from the bilateral thyroarytenoid and posterior cricoarytenoid muscles. Details of the technique are shown for a 5 y/o F with history of Neurofibromatosis Type 2 with left VFI and aspiration and dysphonia. This modified technique for pediatric LEMG has the potential to be a useful tool in predicting return of laryngeal function.
