”Let there be no more scars on the neck” Recently, Dr. Chengzhong Cai of the Department of Nail and Breast Surgery of the Tenth People’s Hospital successfully performed a transoral complete endoscopic thyroid tumor removal surgery for a young female patient. The surgical result was satisfactory and well received by the patient and her family. The incidence of thyroid disease has increased significantly in recent years, and the trend of youthfulness is obvious. Traditional thyroid surgery leaves a 3-5 cm surgical scar on the neck, which becomes a “permanent mark on the neck” of the patient, and this has become one of the important reasons for young people with high cosmetic requirements to avoid surgery. The existing transthoracic or axillary surgery has a long path and a large subcutaneous trauma surface, which still leaves scars on the body surface. Finding a surgical technique with less trauma and less or even no scarring is what neck surgeons are striving for. Transoral thyroid surgery was proposed by German surgeon Thomas Wilhelm, and the world’s first transoral thyroid tumor resection was successfully performed in 2010. Dr. Chengzhong Cai, a nail and breast surgeon at the 10th Hospital, studied this technique in Germany while studying abroad. According to Dr. Cai, this technique requires only three small 0.5 cm incisions in the oral cavity to achieve lumpectomy of the thyroid tumor. Because of the short surgical path and minimal trauma, it really leaves no scars on the body surface and has obvious advantages over the existing transaxillary and areolar surgical methods. Dr. Cai introduced that transoral thyroid surgery technique represents the latest development in minimally invasive neck surgery, which is currently limited to a few countries internationally. The success of this procedure marks the new leading level of minimally invasive thyroid surgery technology. Transoral thyroid surgery is still in the early stage of clinical application. From the analysis of the available cases, patients have significantly less postoperative pain, no wound drainage, shorter hospital stay, and near-perfect postoperative cosmetic results. Except for short-term edema and numbness in the jaw after surgery, there were no complications such as bleeding and infection. Due to the limitation of surgical technique and equipment, this surgery is currently mainly applicable to benign thyroid tumors with single, less than 3 cm in diameter. With the improvement of surgical equipment and the increase of social awareness, it is believed that this procedure will be widely used.
