As early as 2,500 years ago, Hippocrates clearly pointed out that “it is difficult to judge whether a certain medical treatment is effective and superior, but it must cause as little harm as possible to the patient, otherwise the result may be worse than the natural course of the disease itself”. With the continuous development of medical technology and advances in electronic, optical and biological material technology, minimally invasive techniques were born. This technology is a revolutionary advancement in modern surgery, with the goal of “maximizing the patient’s benefit with the smallest possible medical act, and maximizing the patient’s physical and psychological recovery”. It is increasingly recognized and valued by the majority of doctors and patients, gradually replacing traditional surgery, and will predictably become the mainstream of future medical technology. The aesthetic medicine of the 21st century has the characteristics of more humanized, intelligent and minimally invasive. It is from the point of view of humanistic care, in the process of diagnosing and treating diseases, using various advanced and good methods to minimize the damage of patients, reduce their pain and discomfort, so that patients can be diagnosed and treated in a relaxed and comfortable environment, thus making faster and complete recovery from diseases. It is the need to maintain the interests of patients and is the inevitable development of medical science. The so-called minimally invasive cosmetic surgery, as the name implies, is a treatment using minimally invasive surgical methods, thus minimizing trauma to the patient’s body surface and internal tissues. Minimally invasive cosmetic surgery is not only the smallest surgical incision or no surgical incision compared with ordinary cosmetic surgery, but more importantly, it makes it possible to do cosmetic surgery treatment or surgery with less damage to normal tissues, less bleeding, less postoperative patient pain, less inflammatory reaction, faster recovery, less complications, unknown or even no scar, good treatment effect, and High safety, patients do not need to be hospitalized, and even do not affect normal work or less. This is the aim of minimally invasive cosmetic surgery. How long should the small incision of minimally invasive cosmetic surgery be? At present, there is no clear definition at home and abroad, and it is not possible to make a generalization, but also depends on whether the incision is obvious and whether it leaves obvious scars. “Minimally invasive aesthetic” treatment range is extremely broad, mainly including small incision surgery, endoscopic surgery, injection therapy and laser treatment, etc., which is different from the traditional plastic surgery concept, has distinctive features in the field of plastic surgery, and relative independence, can be in a certain range to a certain extent to replace the traditional surgical methods, is currently It is an important and irreplaceable part of the plastic surgery technology.
