The word “beauty” originally originated in ancient Greece and means decoration. The concept of beauty has evolved with the existence and development of human civilization. Marx once said, “The pursuit of beauty is a symbol of the progress of social civilization.” With the improvement of people’s living standard, plastic surgery and beauty has become a technical field indispensable to ensure people’s normal life. In order to better enjoy the services that plastic and cosmetic technology can give us, it is necessary to understand some knowledge about plastic and cosmetic surgery. What is plastic surgery? Plastic surgery is a branch of surgery, which is the repair and reconstruction of defects and deformities of human tissues and organs by means of surgery or tissue transplantation, as well as the reshaping of the normal human form to achieve improvement and beautification of form and reconstruction of function. After treatment, patients with tissue and organ defects or deformities caused by diseases, trauma or congenital deformities can achieve “the injured are not disabled, the disabled are not invalid”; healthy people can be more handsome and beautiful. Plastic surgery is divided into reconstructive surgery and cosmetic surgery. What are plastic and reconstructive surgery and plastic and aesthetic surgery? Plastic surgery is divided into plastic reconstructive surgery and plastic and cosmetic surgery. The former mainly repairs and reconstructs the body surface organs or parts that are congenitally defective or damaged by nature to make them reach or approach normal form and function, (such as burns, burns, frostbite, electric shock, radioactive injuries, cuts, crush injuries, avulsion injuries, tissue defects, scars and deformities after microbial infections; various congenital deformities; all kinds of benign (malignant tumors after removal of defects, and for certain diseases caused by human tissue and organ deformities, defects or dysfunction); and plastic and cosmetic surgery is based on the theory of human form of beauty, through surgical techniques to repair and shape the human anatomy, physiological range of normal defects, in order to enhance the beauty of human form, and to lift people’s repressed and pathological psychology as the purpose of the medical discipline. Aesthetic plastic surgery also includes hair transplantation, tattooing, upper and lower eyelid surgery, mammaplasty, facial wrinkle removal, rhinoplasty, laser, photon cosmetic surgery, liposuction body contouring, abdominoplasty, vulvar genital plastic surgery, etc. For example, external ear reconstruction performed on patients with congenital small or no ears is external otoplasty reconstructive surgery; while ordinary rhinoplasty with silicone rubber prosthesis is cosmetic plastic surgery. The fundamental purpose of reconstructive and cosmetic surgery is to restore or improve the physical appearance of the face through surgical methods to make it as perfect as possible. The ideal surgical result is one that not only improves the appearance, but also does not or only minimally affects the function of the operated area, without serious postoperative complications. In addition to following the universal principles of surgery, plastic surgery must also comply with principles specific to plastic surgery, such as minimally invasive and tension-free principles, in order to achieve perfect results!
