A crooked chin is often the cause of facial asymmetry and can be treated with osteotomy along with a corrective chin. In addition, candidates who undergo surgical treatment should also develop good chewing habits in general to allow normal bite and jaw function to avoid the reappearance of chin asymmetry. A typical chin surgery is to increase the size and appearance of the receding chin to make it more prominent; when viewed from the side, the curvature between the chin and the nose will appear more balanced and coordinated. In some patients, the jawbone is moved forward. In this method, an incision is made inside the mouth, the jawbone is cut horizontally with a saw or chisel, and then the cut jawbone is moved forward and fixed with a wire or small steel plate, and the wound is sutured and wrapped with a dressing. In this procedure, the scar is not visible on the outside because the incision is made inside the mouth. If only moderate enhancement is needed, the surgeon will recommend an artificial chin implant for adjustment, and the incision can be made either inside or outside the mouth. It is best to eat only liquid food for two days after surgery, and stitches can be removed after seven days.
