Chin plastic's method can be divided into osteotomy or prosthesis. Chin is an important structure that affects the face shape, especially the face shape of 1/3. Only when the chin is in harmony with other facial organs can we have a well-defined and attractive facial contour. A beautiful chin is the cornerstone of a beautiful face. Before the prosthesis operation, the doctor should choose the appropriate prosthesis to implant in front of the chin according to the personal situation of the beauty seeker.

Usually, an incision is made in the mouth of the lower lip or an external incision is made under the chin to implant a prosthesis in front of the mandible. After operation, the chin should be fixed with tape to reduce swelling and discomfort.

Up to 20 13, the commonly used prosthesis material is medical silicone prosthesis, and the best material is expanded polytetrafluoroethylene, which has good histocompatibility, rejection and allergic reaction. The disadvantage is that the prosthesis is difficult to carve and place, which requires high operation of doctors and expensive materials, and is not suitable for most beauty seekers. Osteotomy is to move the mandible forward after osteotomy, make an incision in the mouth, move the mandible forward after osteotomy, fix it with steel wire or small steel plate, suture the wound and bandage it with pressure.
