Through plastic surgery to change the jaw more methods, the common way can be achieved through the injection of hyaluronic acid to achieve the purpose of plastic surgery, but also through silicone, tumescent material for filling, in addition to jaw angle plastic surgery, are able to change the jaw shape. 1, hyaluronic acid injection: If the jaw only needs mild adjustment, you can use the method through micro-remodeling, such as the use of hyaluronic acid injection filling, you can achieve better results . It should be noted that hyaluronic acid injection will be gradually absorbed, so it can only last for 6-12 months, after which the injection needs to be repeated to maintain a better jaw augmentation effect; 2, silicone, tumescent material filling: If the jaw is relatively short, you can use silicone or tumescent material for personalized sculpting, and then make appropriate incisions and separations on the surface of the jaw bone to reserve the cavity, and then from the The oral or jaw skin incision will be placed in the middle of the cavity, properly fixed to achieve a good role in extending the jaw; 3, jaw angle plastic surgery: the angle of the jaw angle is too small or jaw angle hypertrophy, through grinding, curved osteotomy and surgical excision of the jaw angle upward to achieve better plastic surgery results. The surgery of jaw augmentation with prosthesis may result in hematoma and skin ecchymosis. In addition, when the incision is made in the mouth for separation, you should not eat normally for about 1 week after surgery to avoid wound infection. If the prosthesis is not properly fixed during the process of placing the prosthesis into the cavity causing the prosthesis to shift, the jaw may become crooked after the surgery. In contrast, bone grinding surgery may cause complications such as hemorrhage, nerve damage, and medically induced fractures. In summary, the specific plastic surgery method needs to be based on your own situation, choose the right way to improve under the guidance of your doctor, and strengthen the post-operative care, and pay attention to the treatment must be carried out in a regular hospital.
