Maxillofacial malformation refers to the malformation of the maxilla or mandible due to various congenital or acquired causes during growth and development, resulting in the formation of maxillary protrusion, mandibular protrusion, maxillary recession, mandibular recession, acromion and deviated jaw. Craniomaxillofacial deformities affect both occlusal function and overall facial appearance. The Craniomaxillofacial Department of our hospital, in cooperation with orthodontists and orthognathic surgeons, can complete comprehensive orthodontic treatment for various complex dental and maxillofacial deformities. The orthodontic and maxillofacial deformities mainly include: 1, mandibular protrusion deformity, i.e., geodesic; 2, mandibular deviation deformity; 3, maxillary protrusion deformity; 4, maxillary recession with mandibular protrusion; 5, bimaxillary protrusion deformity, i.e., acromion; 6, mandibular recession deformity. These deformities not only affect the chewing function, cause cosmetic deformity, and also bring psychological and mental pain. However, for patients above 16 years old, the development of the upper and lower jaws has been basically completed, so it is difficult to be corrected only by simple orthodontics, which requires orthognathic surgery to move the deformed upper or lower jaws to restore the normal occlusal relationship and at the same time The purpose of improving facial appearance is achieved. If you are ready to improve your appearance through orthognathic surgery, you will first need to undergo an X-ray examination of your head, and we will use electronic computer software to take precise measurements of your upper and lower jaws to make a clear diagnosis and propose a surgical treatment plan. You can see the post-operative effect in advance through the simulated surgery. At the same time, our orthodontist will also give you a thorough examination of your oral physiological hygiene, and then suggest some further orthodontic treatment that may be needed after the surgery, which is a good pre-surgical preparation. The surgical procedure usually requires a hospital stay of 7 to 14 days. Under general anesthesia, the procedure is painless and the length of surgery depends on the extent of the deformity and can be completed in 2-4 hours. The incisions are made in the mouth so that no scarring is left on the face. After the surgery is completed, an infusion of antibiotics and hemostatic medication is required for 5-7 days to prevent infection and bleeding. On the first day after surgery, you can usually get out of bed normally. To prevent wound infection, you can only eat warm and cool liquid food during the post-operative hospitalization, and you are prohibited from eating spicy, mutton, seafood and other foods that can easily lead to allergic reactions and affect wound healing. On the 3rd and 4th day after surgery, the swelling of the face often increases compared to the first two days, which is a normal physiological reaction, then the swelling will gradually subside and the effect of surgery will gradually appear. The stitches are usually removed 10-14 days after surgery. When the wound is completely healed and the stitches are removed, you can eat and drink normally.
