At present, there are three kinds of facial plastic surgery, namely mandibular angle plastic surgery, chin plastic plastic surgery and zygomatic plastic surgery. If you want to be a beauty with a small face, you must first know what kind of surgery you want to do. Application of mandibular angle plastic surgery: square face (Chinese character face), pie face, trapezoidal face and mandibular angle plastic surgery are the most effective plastic surgery to turn square face into oval face. Application of mandibular angle plastic surgery: square face (Chinese character face), pie face and trapezoidal face mandibular angle plastic surgery is the most effective plastic surgery to turn square face into oval face. Anatomically, the mandible is composed of mandible, masticatory muscles, subcutaneous fat, skin and other tissues from the inside out. As long as one of these tissues is too thick or developed, it will affect the contour of the face and become a so-called square face, pie face or trapezoidal face. If it is a bone problem, surgery can be performed to polish or remove part of the jaw. At present, oral incision is widely used, leaving no scar on the face. There are still some people whose faces are not beautiful, which may be local fat accumulation or hypertrophy of masticatory muscles on both sides, as long as they are slightly changed, such as injecting biological agents into their faces and liposuction. Chin plastic is suitable for: reduce the chin after the chin, the chin bone is too short, and the chin is a little short. Artificial chin is more natural and has fewer complications. At present, the most commonly used surgical methods are local anesthesia, incision of mouth and lower gum, and no hospitalization after operation. If the jaw is too short, too protruding or skewed, the jaw ratio can be adjusted. Fat accumulation at the edge of the chin can cause obesity around the chin, mouth and neck, and all of them can face-lifting through local liposuction. Zygomatic plastic surgery is suitable: the height of zygomatic bone is closely related to the proportion of other parts of the face, such as the width of mandible. In addition, it is also related to subcutaneous fat. Too little fat will make you look emaciated and your cheekbones too high. For women, the height of the zygomatic bone is stiff and masculine, and the way to change it is to reduce the zygomatic arch and plastic surgery. At present, most of the surgical methods used are oral incision, grinding zygomatic bone and part of zygomatic arch, leaving no scar on the external skin.
