Minimally invasive is the trend of surgical development in this century, and thyroid surgery is also undergoing the same course of minimally invasive development. Since the late 1990’s, laparoscopic thyroid surgery has been widely used around the world. There are some people who say that laparoscopic thyroid surgery is not minimally invasive surgery, but “massively invasive” surgery. Often, the doctors who say so do not perform laparoscopic thyroid surgery, and the so-called massively invasive surgery is just an excuse for refusing to update their concepts and accepting new technologies. Thyroid tumor patients have the demand of minimally invasive cosmetic surgery, and the invention of various minimally invasive instruments and equipment has condensed countless efforts of scientists; as a doctor, he has the responsibility to introduce the concept and technology of minimally invasive cosmetic surgery into the clinical treatment of thyroid tumor. At present, there are more than ten kinds of various types of minimally invasive thyroid cavity surgery that have been carried out, and there are always minimally invasive surgeries that are suitable under the premise of eradicating the disease to improve the cosmetic effect of the neck after thyroid surgery, and to satisfy the requirements of the treatment of the thyroid patients, such as young women with high cosmetic expectations and the professional population. For many physicians, the learning process is arduous, and the simple refusal to take advantage of the disparity in medical knowledge with patients is easy. Currently, there are three main types of pathways to perform laparoscopic thyroid surgery: one is the supraclavicular or infraclavicular pathway, which is more commonly used in Asian countries such as South Korea and Japan, and has the advantage of being close to the tumor location, separating the traumatic surface, and at the same time facilitating the relay of traditional open surgery, but the pathway leaves scarring on the neck; the second is the anterior chest wall or thoracic breast pathway, which has a low incision location, good surgical appearance, and adequate intraoperative visualization, The second is the anterior chest wall or sternomastoid pathway, which has good surgical appearance, good intraoperative visualization, easy to grasp by the surgeon, and can perform bilateral lobectomy, with the disadvantage that the separation of the traumatic surface is large, and the parastomal incision is prone to scarring for the Asian yellows, whereas the European and American races are less likely to do so; and the third is the axillary pathway, which has a better surgical appearance, but can only be performed for the removal of one side of the lobes. In addition, in recent years, some people have tried the retroauricular route and the natural cavity (oral) route, both of which have achieved success in stages and are yet to be perfected. At present, the widely used and technologically stable and mature laparoscopy-assisted neck single small incision caliber approach surgery. The single small incision approach to the neck was pioneered by Italian doctor Paul miccoli in 1997. in 1999, Japanese scholar Shimizu K perfected the technique of external lifting airless chamber. in 2000, scholars from Taiwan introduced ultrasonic knife technology into the procedure. in 2002, Professor Gao Li of Run Run Run Shaw Hospital introduced the technique into China, and made a number of improvements to the operation techniques, forming the “There are three major techniques and one variation: the lumen building adjustment technique, the small lumen endoscopic display technique, the ultrasonic knife use technique and the variation of incision length. This makes the procedure a mature minimally invasive endoscopic-assisted thyroid surgery technique (Modified Miccoli Procedure). Prof. Gao Li has made a significant contribution to the development of this technique. The basic surgical method: An incision is designed in the natural transverse stripe of the human lower neck, and an incision of about 2cm in length is made in the middle of the anterior neck. The working chamber is created directly under the strap muscles by pulling a hook suspension in the natural gap of the thyroid surface tissues, and the resection of thyroid lesions is accomplished with the perfect cooperation of the endoscope without the need of carbon dioxide insufflation in the human body. The so-called perfect cooperation means that in the case that the operation cannot be completed by the direct vision of small incision, the operation can be completed by the cooperation and magnification function of the field of vision of the laparoscope, and at the same time, the thoroughness of the treatment is also guaranteed. (January after surgery) This procedure has a wide range of indications and can perform various thyroid surgeries such as adenoma removal, subtotal thyroidectomy, thyroid lobectomy and radical thyroid cancer surgery. It can make the surgery truly minimally invasive, cosmetic, almost no bleeding, short operation time, thorough treatment and reliable efficacy. Compared with the lumpectomy thyroid surgery carried out in recent years through the breast or axillary approach, it has the advantages of easy operation, less trauma, shorter operation time, wider scope of application, and also does not affect the effect of aesthetics, and achieves the best diagnostic and therapeutic effects, i.e., there should be the best stable state of the internal environment, the smallest surgical incision, the lightest systemic inflammatory reaction, and the smallest scars after the operation. This procedure can be operated or explored under the same direct vision as open surgery, and can also be operated under the magnified vision of the laparoscope for fine dissection and operation, and at the same time, the combination of the two extends the surgical field and the operation range of the surgery, which can completely ensure the thoroughness of the surgery, and it is a combination of the advantages and strengths of the two procedures, namely, the open surgery and the laparoscopic surgery and the application of a procedure. According to my personal practice and understanding, nowadays most of the thyroid tumors can be resected through 2cm, 3cm incision or axillary or thoracic breast approach by laparoscopic surgery, and its thoroughness and safety are even further compared with open surgery, and the pursuit of aesthetic effect of thyroid surgery is no longer a dream.
