Abstract: Objective To study the anatomic landmarks of recurrent laryngeal nerve (RLN) in minimally invasive video-assisted thyroidectomy (MIVAT), and to evaluate the operative skills to avoid nerve injury. Methods 106 patients were enrolled in the study dated between August 2008 and August 2010, in which 8 patients were converted to the conventional thyroidectomy. Intraoperative anatomic landmarks for location of RLN were the gap between trachea and carotid artery (GTC), as well as the middle and posterior portion of tracheal wall. Results 98 RLN were at risk, and 97 (98.98 %) nerves were recognized by means of two landmarks. 1 nerve failed to locate which was non-recurrent laryngeal nerve. Temporary RLN paralysis happened to 1 nerve(1.02 %), and no permanent RLN paralysis appeared. Conclusion GTC combined with middle and posterior portion of tracheal wall are safe and effective anatomic landmarks to locate RLN in MIVAT.
