The recovery time of osteotomy is longer. I have been doing osteotomy for more than 2 years. When I finished it for the first time, Director Zhang Xiaotian told me not to eat hard food in a hurry. The recovery time is long. Good nursing can make the effect better and reduce the recovery time. After more than three months, my face was swollen and my chin felt nothing. I was afraid of sequelae and so on, so I went to ask director Zhang Xiaotian again. He showed it to me and said it was okay, just let me be normal. I'm recovering well now, and I can eat well.
