Methods: Retrospective review of patients who underwent robot-assisted thyroidectomy over 5 years for thyroid cancer, in two centers, one in France and one in USA. Those were compared to a control group who underwent open thyroidectomy. We analyzed demographic data, operative outcome and early oncologic outcome measures including; margins, biochemical and radiological evidence for recurrence. Results: 108 robotic cases and 118 open were included. 28.70% underwent central lymph node dissection and 9.26% had lateral neck dissection.The transaxillary approach was performed in 93.5% and the remaining underwent retroauricular approach.In robotic cases, the mean age was45.58±10.58years and BMI was 26.09±6.47.The average nodule size was2.05±1.5cm.The mean operative time was 161.1±55.99 minutes with 3 patients required conversion to open.8(7.4%) patients developped complications including 1 hematoma, 3 seromas and 5 developed transient vocal cord paralysis.Two(1.92%) had focal positive margins, mean TG level was 0.16±0.4 and 2 (1.85%) developed recurrence 24 and 16 months following initial surgery.In comparison to open approach, the robotic approach had significantly longer operative time (p<001).There was no significant difference in the overall complication rate (p=0.15). Conclusions: Robot-assisted thyroid surgery is a safe and feasible approach for managing selected group of patients with thyroid cancer in the western population, and is associated with sound oncologic outcome.
