1 method is a minimally invasive method, which thins the developed masseter muscle and narrows the width of the forehead and face by punching the face-lifting needle. The disadvantage is that the size and thickness of mandibular angle bone cannot be changed, the face shape does not change much, and the masseter muscle will become larger because of chewing activities, which is not a long-term solution.
The second method is mandibular angle osteotomy, which directly removes redundant bones (mandibular branch, mandibular margin, mandibular outer plate), changes the curvature of the side and the width of the front. If the masseter muscle is too large, it can also be removed by surgery together. The effect of grinding osteotomy is very intuitive and obvious, and the bone will not grow back. Bone shape can permanently maintain the effect of oval face or oval face (weight gain or sagging skin will also change the face shape, and postoperative facial maintenance is very important).
