I just had mandibular surgery. It was made in a relatively large plastic surgery hospital in Guangzhou, and it cost 28,000 RMB. I'm not a drag bottle in any plastic surgery hospital, so I can tell you objectively that cutting the mandible is not as painless as those plastic surgery advertisements say, and it will be cured soon, with zero risk and so on. I remember that I had a hard time the first three days. I put two tubes in my mouth, and the bone doesn't hurt, but the oral wound is very painful, numb and swollen. After three days, extubation was better, and I was at least willing to eat something, but it hurt when extubating. It's almost half a month now, and my face is still a little swollen, almost as big as when I didn't do it, and even a little edema, but the shape of the bone is obviously not so square, which can be observed by touching it with my hands or looking at it with my eyes. Moreover, the lower lip and chin are particularly numb, and it is still not convenient to talk and eat. I have consulted a doctor, and it will take about three months to six months to completely reduce the swelling. The specific time depends on your physical fitness and postoperative recovery. So you should be fully prepared for this operation. This operation is useful, but it is painless and has certain risks. You must have an experienced doctor to help you, otherwise it may lead to facial paralysis or paralysis of lower lip and chin. I hope my answer can help you.
