In 1997, Dr. Paul Miccoli, an Italian surgeon, reported a new surgical procedure: endoscopic resection of parathyroid adenomas through a single small neck incision. This procedure is characterized by the use of the endoscope’s “peep” and its magnified image as a partial substitute for direct visualization, which significantly reduces the size of the incision and eliminates the need for a flap. The use of this procedure has attracted much attention in the field because of the significant reduction in trauma and neck disfigurement. In honor of the first minimally invasive endoscopic procedure in the history of thyroid surgery, the Journal of Surgical Theory and Practice in 2004 named it the “Miccoli procedure” for the first time, and the Chinese Journal of Surgery in 2006 also adopted this title. Domestically, in 2003, Gao Li of Zhejiang University Shaw Hospital published an article entitled “Application of high-frequency ultrasonic knife to perform small-incision, airless intraventricular endoscopic thyroid surgery” in the Chinese Journal of Surgery, which introduced this procedure into our country and improved it. I performed the procedure in 2009 and have completed more than 100 cases. Good minimally invasive and cosmetic results have been achieved.
