Objective:To study the clinical value of endoscopic surgery for thyroid disease.
Methods:In 66 patients with thyroid disease, endoscopic thyroidectomy was performed, including 7 cases of thyroid adenoma,55 cases of nodular goiter,3 cases of thyroid cancer, and1 case of toxic nodular goiter.
Results:Among the 66 cases, endoscopic thyroidectomy was performed sucessfully in 65 cases, but 1 case was changed to open thyroidectomy. The operations  included unilateral sub-total thyroidectomy in 42 cases,and bilateral sub-total thyroidectomy in 21 cases; 3 in cases of thyroid cancer,total thyroidectomy was done in 1 case and unilateral total thyroidectomy plus isthmectomy was performed in 2 cases.The average operation time was 94(50-180)mins,while bleeding volume was 21（10-200）mlls and hospital stay was 9（5-19）days.There were no complications sucahs neural injury indavertent removal of parathyroid glands.No recurrence was found in 1 to 11 months follow up in all the cases（including 3 cases of thyroid cancer）.
Conclusions:Laparoscopic thyroidectomy can be carried out safely and effectively with minimal trauma and rapid recovery,and is the nethod of choice for benign lesion of thyroid.
