The beauty of facial contour is the first condition and the most obvious sign of human beauty, and it is also the external sign of a person's certain behavior and cultural characteristics. Facial contour shaping is aimed at the overall shaping of mandibular angle hypertrophy, high cheekbones, temporal depression, short chin surgery, cheek depression or excessive fat. 1, plastic surgery for mandibular angle hypertrophy. The oriental aesthetic view holds that the mandibular angle should be round and hidden, shaped like "melon seeds". The mandibular angle that affects the face mainly includes mandible, mandibular margin and mandibular angle. Therefore, whether the mandible is beautiful depends not only on whether the mandibular angle is enlarged, but also on the treatment of the enlarged masseter muscle after removing part of the mandibular angle. 2. The width of one third of the face when the zygomatic bone is reduced and the temporal depression is filled mainly depends on the height of zygomatic bone and zygomatic arch. Orientals generally believe that women's cheekbones are slightly lower and appear gentler, so their cheekbones are enlarged, their cheekbones are high, their temples are sunken, their cheekbones are prominent, and their middle faces are too wide, which often gives people a fierce or haggard feeling. Bilateral zygomatic reduction and bilateral temporal biomaterial implantation can be used to make the temporal part plump and the zygomatic part round. 3. Chin augmentation is an important structure that affects the face shape (especially under the face 1/3). Only when the chin is in harmony with other facial organs can we have a well-defined and beautiful facial contour. A beautiful chin is the cornerstone of a beautiful face. The standard chin should lean forward obviously, and there is obvious aesthetic depression under the lip. In the closed state, the lips should be located on the straight line between the tip of the nose and the front edge of the lower end of the chin. The chin is short or backward, which is out of proportion to the upper middle face, making the lower face feel wider. It can be treated by chin osteotomy, bone grafting or chin augmentation with biocompatible materials, so that the proportion of each part of the chin can be coordinated and the goose egg-shaped beauty effect can be produced. At present, the commonly used prosthesis material is medical silicone rubber prosthesis, and the best material is expanded polytetrafluoroethylene, which has good histocompatibility and is not suitable for rejection. The disadvantage is that the prosthesis is difficult to carve and place, which requires a high degree of operation by surgeons and expensive materials. 4, cheek liposuction face-lifting surgery Too much subcutaneous fat accumulation on the cheek will make the face round, which is also commonly known as "baby fat". Others not only have full and round faces, full cheeks and double chins. In this case, local liposuction can be used to extract excess cellulite and restore a firm and clear facial contour; Liposuction can also be performed by phacoemulsification on the cheek. This kind of surgical incision is very small and hidden, which can extract accumulated fat and tighten skin muscles due to the stimulation of subcutaneous tissue. The extraction of subcutaneous fat has the best plastic effect on cheeks and mandibular neck. Shuguang experts pointed out that for the comprehensive shaping of facial contour, it is necessary not only to consider the safety of surgery, but also to communicate with doctors and elaborate design before operation, so as to effectively realize the overall coordination and naturalness of facial contour after operation.
