Objective: Previously, we have reported the feasibility of retroauricular (RA) robotic thyroidectomy. Despite its promising surgical outcomes, there were certain intrinsic mechanical limitations inherent to the da Vinci Si System (Intuitive Surgical, Sunnyvale, California, U.S.A.). Since the advent of an upgraded model, the Xi System (Intuitive Surgical), we have actively incorporated the new model into performing RA thyroidectomy. Here, we intend to verify the feasibility of RA robotic thyroidectomy using the new da Vinci Xi System (Intuitive Surgical) with comparison of the former Si-applied surgery (Intuitive Surgical). Study Design: Comparative analysis. Methods: There were total 165 consecutive patients who received RA robotic thyroidectomy from January 2013 to February 2016. The patients were divided into two groups: Si group (n = 125) and Xi group (n = 40). Perioperative and treatment outcomes were compared and analyzed. Results: Compared with the previous system, new da Vinci Xi system (Intuitive Surgical) enabled insertion of an extra third robotic instrumental arm. Unlike the previous robotic surgical technique, the robotic dissection could be initiated immediately after the establishment of working space and the resulting total operation time could be significantly decreased. There was no difference in the surgical completeness, as confirmed by postoperative thyroglobulin levels. Additionally, flexed EndoWrist (Intuitive Surgical) instruments equipped with the Erbe (Erbe USA Inc., Marietta, Georgia, U.S.A.) system could be mounted, which further facilitated the operation. There were no significant differences in postoperative complications between the two groups. Conclusion: The RA robotic thyroidectomy with the new Xi System (Intuitive Surgical) can greatly facilitate the robotic surgery with comparable or improved surgical outcomes. Its application is expected to open up a new era of robotic neck surgery. Level of Evidence: 4. Laryngoscope, 128:1730–1737, 2018.
