At present, silicone prosthesis is widely used in Korea and all over the world. The surgical approaches are mostly axillary entrance, areola incision and inframammary fold incision, especially axillary incision, which is widely used because of the hidden wound. Now the mainstream is to use an endoscope, with the help of an endoscope. The difference is that the main plastic surgery hospitals in South Korea have a unique technology, that is, zero fascia injury, which minimizes the pain. After operation, only the part covered by skin below the chest will not touch the shell of the prosthesis. Because the fascia separates the breast tissue from the prosthesis, the breast tissue causes bacterial sensation and less staining, which reduces the incidence of capsular contracture.
