Abstract
Reconstruction of recurrent nerve palsy is two methods, one is static, the other is dynamic.
Static methods are mediofixation of vocal cord, silicone injection, etc. Dynamic methods are nerve reconstruction, transplantion of nerve-muscle complex. But, dynamic methods are rare of recovery from paresis. In operating time of thyroid cancer or esophageal cancer, immediate anastomosis of cut end is easy and expected recovery from paresis. In addition to end-to-end anastomosis, anastomosis with cervical vagal nerve is available for cut in thoracic space.
