“Let the neck no longer have a scar” Recently, Dr. Cai Chengzhong of the Department of Nail and Breast Surgery of the Tenth People’s Hospital successfully performed a transoral complete endoscopic thyroid tumor resection for a young female patient. The surgical result was satisfactory and well received by the patient and her family. The incidence of thyroid diseases 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 patient’s neck, and this has become one of the major reasons for young people with high cosmetic demands to avoid surgery. Existing trans-thoracic or axillary surgeries have long paths, large subcutaneous trauma surfaces, and still leave scars on the body surface. Finding a surgical technique that is less invasive, less scarring or even scarless is what neck surgeons are striving for. Transoral thyroid surgery was proposed by German surgeon Thomas Wilhelm, who successfully performed the world’s first transoral thyroid tumor resection in 2010. Dr. Cai Chengzhong of the Department of Thyroid and Breast Surgery at the 10th Hospital learned this technique during his studies in Germany. According to Dr. Cai, this technique requires only three small incisions of 0.5cm in the oral cavity to remove the thyroid tumors under a laparoscope. Due to the short surgical path and minimal trauma, the procedure can be performed without leaving any scars on the body surface, which is an obvious advantage compared to the existing transaxillary and areola surgical methods. According to Dr. Cai, the technique of transoral thyroid surgery represents the latest development in the field of minimally invasive neck surgery, which is currently limited to a few countries internationally. The success of this procedure marks a new level of leadership in minimally invasive thyroid surgery. Transoral thyroid surgery is still in the early stage of clinical application. From the analysis of the available cases, the patients’ postoperative pain is significantly reduced, the wounds are not drained, the hospital stay is shortened, and the postoperative cosmetic results are nearly perfect. Except for the short-term edema and numbness in the jaw after surgery, there were no complications such as bleeding and infection. Due to the limitations of surgical techniques and equipment, this procedure is currently mainly applied to benign thyroid tumors that are single and less than 3cm in diameter. With the improvement of surgical equipment and the increase of social awareness, it is believed that this procedure will be widely used.
