Hello! Jaw plastic surgery will definitely hurt. Although the operation is performed under anesthesia, there will still be some pain and swelling after anesthesia. Postoperative nursing is very helpful to the effect. Don't eat spicy food to prevent oral infection caused by residue. At the beginning of the operation, it is recommended to eat some semi-liquid foods, such as wonton and egg soup. The operation will cost about 50 thousand yuan. I hope my answer is helpful to you! I wish you happiness!
