Subjects that suffering from papillary thyroid carcinoma will be randomized into Study Group (gasless transaxillary posterior endoscopic thyroidectomy ) or Control Group (conventional open thyroidectomy). Measure the outcomes as following, early complication rate, life quality score, the number of dissected lymph nodes, the volume of residual gland, 3-year recurrence rate, operation duration, hospital stays, hospitalization expense, and inflammatory and immune response.
To evaluate the feasibility and safety of gasless transaxillary posterior endoscopic thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) and open radical thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) as the current standard surgical treatment mode in terms of feasibility and safety of radical thyroidectomy.
