The sun is blazing in the summer of July, the roaring army of plastic surgery at this time are gathered to the major plastic surgery hospitals, ready to fight for their beauty plus points, facial contouring is the most effective choice for facial beauty plus points, in the end, which surgery is the category of facial contouring? How should beauty lovers choose? What are the considerations? The jaw angle plastic: jaw angle hypertrophy is generally more bilateral, unilateral is not uncommon. Often related to excessive snacking and chewing gum (or betel nut) during adolescent physical development, can also be caused by grinding teeth at night. All these make the maxillary muscle group (bite muscle, pterygoid muscle, etc.) over-exercised, stimulating the muscle and bone development of the mandibular angle area, and eventually the appearance of “square face deformity”. Therefore, it can be considered that the cause of jaw angle hypertrophy has two parts: one is the bony hypertrophy of the angle of the mandible; the other is the overdevelopment of the bite muscle protruding from both sides of the cheek. In each patient, the influence of the two causes may be different, either bony or muscular, but from clinical experience, both often occur together. Some patients also have a genetic cause, and retrospectively their parents or relatives often also have an enlarged jaw angle. Surgical options generally include mandibular angle osteotomy and mandibular bone grinding osteotomy, both of which can be applied in conjunction to achieve a V-faced effect! The zygomatic bone contains two parts: the zygomatic body and the zygomatic arch; the location of the zygomatic body is below the outer orbit of the eye; it extends backward around the outside of the cheek to the sideburns, which is the zygomatic arch. If the zygomatic body is overdeveloped, it will bulge forward, resulting in high cheeks; if the zygomatic arch is overdeveloped, it will expand to the sides, resulting in wide cheeks. Commonly used surgical methods: zygomatic bone osteotomy and lowering surgery: enter through an incision in the mucosa above the mouth, cut the junction of the zygomatic bone body and the zygomatic arch, and cut off the back edge of the zygomatic arch from the sideburns, move the entire zygomatic arch inward, and fix it with a titanium plate to sculpt the zygomatic bone into a smooth and coordinated curve. Zygomatic bone grinding and lowering surgery: It is suitable for those who do not have obvious widening of the zygomatic arch. Chin plastic surgery: The chin has distinctive facial features and personality characteristics, occupying a very important position in the facial contour, whether front or side, the shape of the chin has an extremely important impact on the overall image of the face, in recent years the shape of the chin is increasingly valued by people, and often associated with personal character traits, normal or upturned chin is not only regarded as a sign of beauty, but also seen as wisdom, courage, perseverance, charm. On the contrary, it is a reflection of weakness and indecisiveness. The chin plastic surgery includes: chin filling: chin filling refers to the use of autologous bone, artificial bone or other biological substitutes placed under the chin bone after shaping in order to increase the length and protrusion of the chin, to improve the facial contour of the surgical method, mainly applicable to the correction of mild to moderate small chin deformity with normal occlusal relationship. Chinplasty: In the early 1980s, Bell proposed chin osteotomy with extensive soft tissue tissues, which is an ideal method to correct various chin deformities because the blood flow of the chin bone segment is ensured, the bone resorption is greatly reduced after surgery, and the ratio of soft tissue changes after osteotomy is more similar. Suitable for chin recession, chin too short, chin too long, giant chin and the surgical correction of partial chin. Facial plastic surgery precautions: 1, women should avoid the physiological period; 2, physical health, avoid colds and other systemic diseases; 3, before surgery should stop smoking. Aspirin, birth control pills and certain anti-inflammatory drugs can cause increased bleeding, so these drugs should be discontinued 2 weeks before surgery to avoid bleeding during and after surgery; 4, surgery in the mouth to avoid breaking, stomatitis, gingivitis and other conditions, it is best to scaling 2-4 weeks before surgery; 5, preoperative head CT, CR film, to facilitate communication with the doctor, according to the situation to determine the surgical plan.
