Hello, I'm Dr. Xue Zhiqiang, and I'll answer your question: After mandibular angle plastic surgery, there may be swelling, but don't worry too much, because these swelling are normal physiological reactions, and most operations will have swelling problems. It only takes three to five days to recover and you can go back to your original life. However, we should know that if the swelling problem is not relieved for a long time, it may be the failure of the operation. We should take timely adjustment measures to ensure the success of mandibular angle plastic surgery.
