It usually takes 3 months for jaw plastic surgery to return to a more natural effect. Although maxillofacial plastic surgery is currently the most direct and effective way to change the face shape, the results are not immediately visible after the surgery. Because there will be a swelling period of the wound after surgery, the facial width will not change significantly from the appearance, and some may even be wider. This period generally lasts for about 3 months. As the swelling subsides, the effects of the surgery will gradually become apparent.
