Facial contour surgery is a kind of cosmetic plastic surgery to improve facial curve, coordinate the proportion of the whole face more perfectly, improve aesthetic requirements and improve the image as much as possible. In a word, it is a beautiful operation to remove or grind away the bones that lead to the disharmony of the whole face and improve the facial contour.

The original MMM contour line is the basic frame of the face, so the face has been improved the most in plastic surgery, which can be divided into frontal silhouette and 45-degree silhouette. The main factors that determine the forehead contour can be divided into the curve from the lower part of the face to the chin, the subauricular jaw, the face, cheekbones, temples, the lateral curve of the forehead and the upper curve. The main factor that determines the 45-degree profile image is the front contour element, and the profile images of eyes, upper eyelids and lower eyelids can also be seen. The profile of the side is formed by the following factors: chin, subauricular mandible, upper and lower lip lines, nose and lip hook, nose profile, cheekbones, eyebrows, forehead and so on.

The above MMM content shows that the facial contour is different according to different visual angles, and the contour elements are different according to their respective contours, so the surgical plan is determined through these comprehensive evaluations.

MMM original bimaxillary surgery has two situations.

First of all, the most typical is land, right? This is also divided into two situations. First, the chin is prominent, the mouth is flat, and the teeth are misaligned, which is what we often say. In this case, the mandible is pushed forward to solve the problem of tooth occlusion. Second, simple chin protrusion, but normal occlusion of teeth.

The second kind is protruding mouth, which usually appears at the same time as chin-less, and can't be separated. When you laugh, your gums leak.

There is also a real chin-less.

Finally, facial asymmetry, a good judgment, is to see whether the eyebrows and chin are in a line, or whether the upper and lower lips are inclined, and whether the head looks crooked from the front.
