Feasibility and surgical approach of transaxillary robotic thyroidectomy without CO2 insufflation

Background.Our objective was to evaluate the anatomic basis for robotic‐assisted transaxillary thyroidectomy and to determine its feasibility in a prospective clinical trial.Methods and Results.Using the da Vinci Surgical Robotic System, we performed 5 cadaveric dissections, via transaxillary approach without gas insufflation. Once the safety and feasibility of this approach had been demonstrated in cadavers, it was utilized to perform a thyroid lobectomy in a patient. The da Vinci system provided excellent visualization of the recurrent and superior laryngeal nerves, parathyroid glands, and paratracheal lymphatics. After the 5 cadaver dissections, the procedure time diminished from >90 minutes to Conclusion.Robotic‐assisted transaxillary thyroidectomy is feasible with proper instrumentation and an understanding of the surgical anatomy. Based on this preclinical laboratory study and our experience in 1 patient, further evaluation of this approach in the setting of a prospective clinical trial is warranted to determine standardized criteria identifying patients who would benefit from this approach. © 2009 Wiley Periodicals, Inc.
