目的　探索一种能同时恢复麻痹声带内收及外展功能的治疗方法。方法　对狗一侧喉返神经及喉上神经运动支联合麻痹的喉内肌 ,采用颈袢胸骨甲状肌肌蒂移植于麻痹侧环杓后肌 ,颈袢甲状舌骨肌肌蒂移植于麻痹侧环杓侧肌作为实验组 ,并仅用颈袢胸骨甲状肌肌蒂移植于麻痹侧环杓后肌作为对照组。术前及术后 4个月行声带录像、喉肌电图检测、组织学检查。结果　术后 4个月所有动物均不同程度地恢复了麻痹声带的生理功能。实验组术侧声带内收运动明显优于对照组。所有受植喉肌均出现诱发动作电位 ,组织学检查显示受植肌获神经再支配 ,肌肉形态结构基本正常。对照组失神经支配的环杓侧肌显示肌肉萎缩、变性。结论　采用神经肌蒂移植同时恢复麻痹声带内收、外展运动是可行和有效的 Objective To explore a method of treatment that can simultaneously recover paralytic vocal cord adduction and abduction functions. Methods The throat muscles of the laryngeal nerve of the laryngeal nerve and parapharyngeal branch of the laryngeal nerve were transplanted into the posterior ciclofeclampus muscle of the paralyzed side with the cervical sternocleidomastoid muscle pedicled. Cricoid hemispheres were used as the experimental group, and only the posterior thyroid muscle pedicel was transplanted to the paralyzed cricothyral posterior muscle as the control group. Preoperative and postoperative 4 months vocal cord video recording, laryngeal EMG test, histological examination. Results All animals recovered the physiological function of paralyzed vocal cords to varying degrees 4 months after operation. The experimental group’s vocal cord retraction movement was significantly better than the control group. All the induced plantar laryngeal muscle evoked action potentials, histological examination showed that by the myenteric nerve re-domination, muscle morphology was normal. In the control group, the denervated inner circumflex muscle showed muscle atrophy and degeneration. Conclusions It is feasible and effective to use the neuromuscular pedicle graft to restore the paralyzed vocal cord adduction and outreach at the same time
