Professor Xu, my mouth is the biggest problem that affects my self-confidence. It is not only protruding but also slightly tilted to the right side. I have rarely taken pictures. In order to change this situation, I put a pad on it. My chin, however, did not change at all. Instead, my face became longer. It was very old-fashioned. I have been asking about this method of improvement. Someone suggested that I go to South Korea for double jaw surgery, but the doctor there said that after the operation, it would still be still there. For orthodontic treatment, I need to stay in Korea for more than a month. I have no choice in terms of time, and the cost is very high, so I can't afford it. I didn't know much about this before. I asked many plastic surgery hospitals, but I didn't dare to do it there. After looking for it for a long time, I finally saw the news on the Internet that Shanghai No. 9 Hospital can treat this surgery. I suddenly felt that I saw hope, but I am not in North Shanghai myself. I want you to give me some advice on doing this surgery. Where can I go to do it? It’s quite a long way, especially since I need to have orthodontics after surgery. My teeth’s occlusion is not bad, but my dental arches are protruding. I heard that I don’t need orthognathics after this surgery, right? The tooth occlusion is normal, but the dental arch is the alveolar protrusion. Can orthodontics achieve the effect, or does surgery have to be performed? Which one is more effective? I hope to retract the mouth to make the mouth shape look better and change it. Can the crooked mouth be made more beautiful? Can this surgery change the shape of the face? If I have this surgery, will I have to remove the previous chin pad? Can you get this? Is this included in the cost of surgery? Or should I go to a plastic surgery hospital to remove it and then have surgery again? After the osteotomy is retracted, it is fixed with material. Will this material grow with my own bones in the future? There won’t be problems in the future such as loosening of the cut part or bite when the mouth is opened, right? Or if the fixing material falls off, there won't be any problems for several years after the surgery.
