Feasibility and Safety of a New Robotic Thyroidectomy through a Gasless, Transaxillary Single-Incision Approach

. Because the authors included patients with welldifferentiated thyroid carcinoma 2 cm and excluded those with definite extrathyroidal tumor invasion, how did they include T3 and T4a lesions? . Similarly, they excluded patients with lateral neck node metastasis, so how did they include N1b lesions? . Why did they exclude the distant metastasis, since a well-differentiated intrathyroidal follicular thyroid cancer with a distant solitary focus can be removed as safely as one without any distant metastasis? . The authors followed the American Thyroid Association recommendations for thyroidectomy. However, the 2009 American Thyroid Association guidelines (Recommendation 26) recommend total or near total thyroidectomy for tumors 1 cm and lobectomy for low risk tumors 1 cm, and do not recommend subtotal thyroidectomy.
