双侧声带麻痹的治疗,至今效果仍不理想。虽然肌肉刺激、神经移植、喉成形术、带蒂的神经肌肉瓣移植以及激光杓状软骨切除等在治疗声带麻痹有一定的疗效,但术后声带仍不能外展,以致拔管困难。作者将膈神经与舌下神经吻合,然后把含有舌下神经分支的肩胛舌骨肌移植到丧失神经支配的环杓后肌上,以恢复声带在吸气时的外展功能。以3只成年猴为实验对象,经颈部切口,暴露喉返神经及
The treatment of bilateral vocal cord paralysis, the effect is still not satisfactory. Although muscle stimulation, nerve transplantation, laryngoplasty, pedicled neuromuscular flap transplantation and laser arytenoid cartilage resection in the treatment of vocal cord paralysis have a certain effect, but postoperative vocal cord can not be outreach, resulting in extubation difficult. The authors anastomosed the phrenic nerve to the hypoglossal nerve and then transplanted the pubococcygeal muscle, which contains the branch of the hypoglossal nerve, to the posterior lead of the cricothyroidal that lacks the innervation to restore the outreach function of the vocal cord during inspiration. Three adult monkeys were used as experimental subjects, and the recurrent laryngeal nerve was exposed through the neck incision
