单侧声带麻痹的治疗方法多种多样，但迄今为止，很少有客观的研究来评价颈袢神经移位的功能效果。 6只犬行单侧喉返神经切断后立即与颈袢胸甲分支吻合。 术后5 ~ 6个月，进行发声效率和声学参数、视频喉镜检查、视频频闪镜检查和诱发肌电图检查。 在正常电诱导发声和模拟单侧喉返神经，颈袢，和袢喉返神经吻合部位进行了相同的测量，在8个对照犬。 在所有接受神经移植的动物中发现了神经再支配的证据，这取决于在发声期间从移植神经到再支配脊髓的电刺激的程度。 在没有电刺激的神经转移，生理性声带运动不能引起从再神经支配的脊髓。
There are a variety of methods for treating unilateral vocal cord paralysis, but to date there are few objective studies that evaluate the functional results of nerve transfer from the ansa cervicalis. Six dogs underwent unilateral recurrent laryngeal nerve section with immediate reanastamosis to the sternothyroid branch of the ansa cervicalis. After 5 to 6 months, measurements of vocal efficiency and acoustic parameters, videolaryngoscopy, videostroboscopy, and evoked electromyography were performed. Identical measurements were made in eight control dogs during normal electrically induced phonation and a simulated unilateral recurrent laryngeal nerves, ansa cervicalis, and the ansa-recurrent laryngeal nerve anastamosis site was performed. Evidence of reinnervation was found in all of the animals that underwent nerve transfer were dependent on the degree of electrical stimulation from the transferred nerve to the reinnervated cord during phonation. In the absence of electrical stimulation to the nerve transfer, physiologic vocal cord motion could not be elicited from the reinnervated cord.
