A fully reliable means of rehabilitating patients with bilateral vocal cord paralysis has not yet been developed. In order to improve upon existing solutions to this problem, the authors have recently described a laryngeal pacemaker, initially tested through stimulation of a cross-over nerve-muscle pedicle from one sternohyoid muscle to the other in the canine. Afferent stimuli, initiated through elongation of the airway during inspiration, were detected by a linear strain gauge sutured to the tracheal rings and appropriately amplified. The current report deals with the application of this concept to pace a nerve-muscle pedicle reinnervating the posterior cricoarytenoid muscle. Videoscopic and cinematographic documentation of electrically paced abduction of the reinnervated vocal fold, synchronous with inspiration, was clearly demonstrated. Only miniaturization of an implantable electronic amplifier remains to permit an attempt at pacing of the paralyzed larynx in humans.
目前尚未开发出一种完全可靠的双侧声带麻痹患者康复方法。为了改进现有针对该问题的解决方案，作者最近描述了一种喉起搏器，最初是通过刺激犬类中从一块胸骨舌骨肌到另一块胸骨舌骨肌的交叉神经肌肉蒂来进行测试的。吸气时气道伸长引发的传入刺激，由缝合在气管环上的线性应变片检测，并进行适当放大。本报告涉及将这一概念应用于为重新支配环杓后肌的神经肌肉蒂起搏。清晰地展示了在电刺激下，重新支配的声带外展与吸气同步的视频镜检和电影记录。仅剩下可植入电子放大器的小型化，以便尝试对人类麻痹的喉部进行起搏。
