Purpose: Various new techniques in thyroid surgery have been developed to improve visualization and reduce risk of complications. New approaches for robotic endoscopic thyroidectomy help to prevent neck scarring and improve surgical ergonomics. The purpose of this study was to compare the efficacy and adventages of an axillo-breast approach (AB group) and an only-axillary approach (OA group) in robotic endoscopic thyroidectomy. Methods: Between November 2008 and July 2014, axillo-breast approach was performed in 128 patients and only-axillary approach was performed in 128 patients for robotic endoscopic thyroidectomy. We compared tumor characteristics, surgical outcomes, and postoperative complications between the two approaches. The homogeneity between two groups of general characteristics was analyzed by independent t-test, fisher's exact test, Chi-square test. Results: There were no differences in terms of tumor characteristics, extent of thyroidectomy, retrieved nodes, and postoperative complications between the two approaches. The patients in OA group can avoid breast scar. Conclusion: Our techniques of AB and OA approaches for robotic endoscopic thyroidectomy are safe, feasible, and cosmetically excellent procedures. Also the OA approach for robotic endoscopic thyroidectomy is an attractive surgical option for patients with thyroid tumor who want an avoid breast scar.

Background and Objectives : To assure the surgical completeness of the gasless endoscopic thyroidectomy via single incision axillary approach using flexible videoscope which provide wide angle and working space, we compared single incision axillary approach and axillo-areolar approach by means of clinical, surgical outcomes. Materials and Methods : From March 2011 to July 2012, 24 patients who had underwent endoscopic thyroidectomy via transaxillary approach were enrolled. Of total, 17 patients underwent single incision axillary approach(group I) and the other 7 underwent axillo-areolar approach(group II). Results : Patient demographics, surgical indications were similar between the two groups. The operating time(group I 144.6min, group II 153.6 min ; p=.29), blood loss(group I : 55.4cc, group II : 35.7cc : p=.64), hospital stay(group I : 4.2days, group II : 4.4 days ; p=.65) were similar in the two groups. Overall, two patients in group I(2/17, 11.8%) experienced postoperative complications, including one hematoma and one seroma. Due to narrow working space, one patient was change to axillo-areolar approach during single incision axillary approach with $30^{\circ}$ rigid endoscope. Conclusion：Single incision axillary approach is safe and effective similar to other endoscopic thyroidectomy methods using flexible videoscope. Different with $30^{\circ}$ rigid endoscope, 10-mm flexible videoscope can put inside the axillary inicision site in different axis with endoscopic instruments. This difference in endoscopic axis help to prevent crash with endoscopic instrument.
