Abstract    Unilateral vocal cord paralysis caused by injury to unilateral recurrent laryngeal nerve (RLN) injury is one of the most common and serious complications of thyroid surgery. Main manifestations include varying degrees of hoarseness，coughing，and aspiration，which greatly affect patients’ quality of life.The best treatment for vocal cord paralysis is reinnervation of the laryngeal muscles so as to recover the physiological function of the paralyzed larynx，which consists of nerve exploration and decompression，end to end anastomosis of RLN，ansa cervicalis to RLN anastomosis，free nerve graft transfer，reinnervation surgery combined with medialization of vocal cord. Among which ansa cervicalis to RLN anastomosis might be the most optimal option for the patients. Surgical indications should be strictly controlled and some surgical techniques and tips should be followed, which will be introduced in the present study.
