Facial surgery will certainly bring the possibility of trauma or complications, but some of them are unavoidable and some are due to the physician’s own quality or improper post-operative care of the candidate. Precautions before surgery: 1. no organic lesions of important organs, such as heart disease, hepatitis, nephritis, pneumonia and other diseases; 2. no oral infection sources, such as periodontitis, oral ulcers, etc.; 3. routine laboratory tests of blood and urine, chest X-ray and electrocardiogram and other routine health checks before surgery; 4. perform “mandibular surface tomography” and 4. Perform “mandibular surface tomography” and lateral image X-ray examination of the mandible. Post-operative diet: 1. Keep the mouth clean to prevent post-operative infection after facial reshaping surgery. 8 hours after surgery, you can eat liquid food, such as milk, juice, broth, etc.; 2. 14 hours later, you can eat semi-liquid food, such as sour milk, egg custard, noodle soup, thin rice, etc.; 3. Postoperative swelling treatment: 1. Swelling is an inevitable reaction to surgery, so the work to combat swelling should start before surgery, and surgery to avoid menstruation is for this reason; 2. If only the bone is removed during the surgery, the swelling is lighter, while the muscle is removed, the swelling is more obvious; 4. Some candidates will have their swelling reduced in 2 to 3 weeks, and they can recover after 1 month, which has little impact on their work and life. Post-operative scarless method: If external incisions are used for face reshaping surgery, they will generally leave scarring, the difference is that some people leave scarring that is not obvious and easy to disguise, but some people do the same surgery but there will be more obvious scarring, which seriously affects the beauty. The main reason for this consequence is poor surgical stitching. If this factor is excluded, it is likely that the candidate is due to a keloid. The incision scar left by surgery can be surgically removed to make it less obvious for non-keloid people, but it cannot be remedied for keloid people, because another surgery will only leave a bigger scar. There is no effective method to test for scarring, and the best way to avoid scarring is to adopt an intra-oral incision for surgery. The intraoral incision without scarring is the trend of facial plastic surgery. What should I do if my face is asymmetrical after surgery? Re-operation: Facial reshaping surgery is not as precise as polishing parts on an industrial assembly line, the surgeon has to rely more on his rich clinical experience to master the degree of bone, muscle and fat removal, otherwise the post-operative face is prone to be big on one side and small on the other. If there is a significant asymmetry between the left and right side of the face, a new surgery is needed to adjust it. Injection method: Another feasible method is the injection method, because the face shape is affected by the skeletal form, but also by the muscle, fat form, can be injected through the large side of the face Botox or de-inflammatory pine A, so that this side of the face muscle, fat layer thinning, although the left and right face bones are still asymmetric, but after muscle adjustment, from the appearance of the basic symmetry. Unilateral bite muscle physical enlargement method: The chewing habits of people also affect the symmetry of the face, so if the asymmetry between the left and right side of the face is relatively mild after surgery, it can be improved by using methods such as unilateral chewing gum. By the same token, people who have obtained the ideal face shape after surgery should develop proper chewing habits from now on to avoid ruining the beautiful face shape. Don’t be demanding: Strictly speaking, most people have slight asymmetry in their faces, so if there is no obvious asymmetry, there is no need to be too demanding. If you are having a bone reshaping surgery, the post-operative swelling will be obvious and will last for 2 weeks, and after 1 month, strangers will not feel anything different about your face. If it is a simpler surgery such as facial liposuction, you can basically recover in about 1 week, and you can achieve a completely natural effect in about half a year.
