Shaping the mandibular angle is one of the methods to change the face shape, which makes the facial contour lines more beautiful and smooth, thus achieving the ideal face shape. To do this kind of plastic surgery, you must choose the method that suits you. Mandibular angle plastic surgery is to make a 3 cm incision in the mouth after local anesthesia, and then treat the mandible accordingly. At the same time, it can remove the buccal fat pad and enlarge the chin. There is no scar on the face after operation, which is natural.
