Objective To understand the research status, advantages and disadvantages, indications and contraindications, as well as the current challenges and countermeasures, controversies, and future development of gasless trans-subclavian approach endoscopic thyroidectomy (GTAET). Method The relevant domestic and international literature on GTAET was reviewed. Results In terms of oncological outcomes (such as the number of central lymph nodes dissected), GTAET is comparable to traditional open surgery. It demonstrates markedly higher postoperative cosmetic satisfaction and significantly lower incidences of anterior neck paresthesia and swallowing traction discomfort. Compared to other endoscopic approaches (such as the transaxillary approach), GTAET offers advantages including a shorter surgical path, less trauma during cavity creation, a better visual field for central lymph node dissection, and a shorter operative time. It also avoids CO2 insufflation-related risks such as subcutaneous emphysema and hypercapnia. The main limitations of this technique are its generally longer operative time compared to open surgery and the potential for increased postoperative drainage. Furthermore, it faces several technical challenges and application difficulties in clinical practice, including the optimization of specialized instruments, standardization of surgical procedures, and management of lateral neck lymph node dissection. Conclusions GTAET is a safe and feasible minimally invasive surgical approach for thyroid disease. While ensuring thorough tumor eradication, it combines the advantages of a well-concealed incision, excellent preservation of anterior neck function, and the safety and convenience of gasless technique. It also has a relatively manageable learning curve, making it an excellent surgical option for patients with thyroid tumors who prioritize cosmetic outcomes and quality of life.
