Facial contour shaping includes: 1. Plastic Surgery for Maxillary Angle Hypertrophy 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 and face-lifting surgery Too much subcutaneous fat accumulation on the cheeks will round the face, 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. 5. Botulinum toxin injection-A simple and effective method for simple masseter muscle hypertrophy is to inject botulinum toxin A into the masseter muscle on the basis of surgical partial resection to make the masseter muscle partially atrophy. Try not to lie down for a few hours after injection, but exercise the masseter muscle to make the efficacy of Botox spread evenly. At this time, people's chewing power will drop, and they will gradually get used to it in a few days. Three months after injection, the face-lifting effect reached its peak, which could reduce the masseter muscle by about 30%, and the longest effect could last for 6~ 12 months. If you want to maintain the effect, you need to repeat the injection after one year. If you delay the recovery of masseter muscle, you should eat less hard and tough food. It is only suitable for the big face with hypertrophy of masseter muscles on both sides. You can bite your teeth hard and test if the masseter muscles on both sides of your cheek are hard and big. Pregnant women, lactating women and people who are allergic to penicillin cannot use it, and patients with systemic neuromuscular diseases such as local skin infection and myasthenia gravis are also prohibited.
