治疗单侧声带麻痹的方法较多,但评价颈神经袢移植后喉功能结果的客观研究很少。本实验以6只狗为模型,切断一侧喉返神经并立即与颈神经袢的胸骨甲状腺支吻合,5～6个月后测量发声功效及声学参数,并作电视喉镜、电视喉动态镜、诱发肌电图及神经传导速度观测。另用8只狗作对照组,观察正常电刺激、声带发音和模拟单侧喉返神经麻痹时的各指标。两侧声带肌、喉返神经、颈神经袢、神经袢-喉返神经吻合部位均作组织学检查。实 There are many ways to treat unilateral vocal cord paralysis, but there are few objective studies to evaluate the laryngeal function after cervical nerve 袢 transplantation. In this experiment, 6 dogs as a model, cut off the recurrent laryngeal nerve and immediately with the cervical nerve sternum thyroid branch anastomosis, 5 to 6 months after the measurement of vocal function and acoustic parameters, and for video laryngoscope, video throat dynamic lens , Induced electromyography and nerve conduction velocity observations. Another eight dogs as control group, observe the normal electrical stimulation, vocal cord pronunciation and simulate unilateral recurrent laryngeal nerve paralysis of the indicators. Vocal cord muscle on both sides, recurrent laryngeal nerve, cervical nerve plexus, nerve 袢 - recurrent laryngeal nerve anastomosis were made for histological examination. real
