Unilateral arytenoid adduction improves voice in a patient with bilateral vocal fold immobility

摘要

Bilateral vocal fold immobility (BVFI) due to prolonged endotracheal intubation resulted in aphonia without any airway morbidity and was treated by several reconstructive procedures. Laryngeal reinnervation and silicone implantation failed to medialize one of those two fixed cords. Arytenoid adduction (AA) eventually achieved this goal. To select an optimal reconstructive procedure, a careful perusal of the history and head and neck examination including laryngeal electromyography, are necessary to determine the causes. AA procedure played an essential clinical indication in this study, not just an adjunct to the medialization laryngoplasty as usual. Since both the vocal cords positions were ranked as lateral positions subjectively, the full adduction for one of those two fixed vocal cords was performed without significant airway obstruction. The practice in this study provided an experience in correcting the voice in patients with BVFI. We need further experience to medialize the vocal cord in an appropriate magnitude since its counterpart may position variously and compromise the airway.
