□ Munster Leo, an internationally renowned plastic surgeon in Wei Yuan, said: "It is not only white and smooth skin but also perfect facial contour that determines the beauty of appearance." In the face of the overwhelming advertisements such as "thin face", "big face becomes small face" and "making a pointed chin", can you not be tempted? But blindly pursuing a beautiful face can only violate the aesthetic standards of face. When the aspect ratio of the face is close to or in line with the golden section ratio, that is, 1: 1.6 18, the face looks good. Plastic surgeons operate according to this standard and according to the structural characteristics of facial skeletal muscles and subcutaneous fat. It will also reshape the perfect facial contour according to different temperament and personality characteristics. Face shape is determined by facial bones and soft tissues. Bones, namely mandible, cheekbone and frontal bone, determine the facial contour. Soft tissues include skin, muscles, subcutaneous fat and various fat pads, which make the face fuller and more stereoscopic. The so-called "face-lifting" technique is actually a therapy to reduce the height or thickness of some areas of the face through surgery or drugs, so that the facial contour is more distinct and the three-dimensional effect is stronger. Some causes of facial hypertrophy are mainly hard tissue, some are mainly soft tissue, and some people have both. Therefore, choosing the focus to complete the "face-lifting" operation can achieve satisfactory cosmetic results. Surgery should be based on the overall beauty, and the overall harmonious facial contour can be obtained through the harmonious collocation of all components and the comprehensive selection of appropriate methods. So what kind of surgery should be taken for different face shapes? For those with swollen cheeks (apple-shaped face) and fat accumulation under the chin (double chin), excess fat tissue in the cheeks and chin area can be removed, meanwhile, the buccal fat pad can be removed to improve the contour of the front cheek, and the "face-lifting needle" can be injected to shape bilateral mandibular curves, so that the facial contour is clear and the face has a three-dimensional soft and exquisite shape. If mandibular angle hypertrophy is accompanied by masticatory muscle hypertrophy, mandibular angle osteotomy or masseter muscle milling and partial resection can be used to obtain a handsome face. For those whose cheekbones are too high and protruding, and whose middle face is too wide (with a "diamond face"), bilateral cheekbones should be reduced, and temporal filling (temporal filling) should be adopted to make the temporal part plump and the zygomatic part round. For people with small jaws or short chins, chin augmentation can be used to restore the proportion to the upper middle face and produce a beautiful face in the shape of a goose egg.
