Zhimei Plastic Surgery Hospital tells you that adult cleft lip repair is mainly aimed at rabbit lip repair as a child, and the effect is not good. I want to do a second-stage repair operation to ensure the postoperative effect of cleft lip. Generally speaking, the operative age of unilateral cleft lip is 3 ~ 6 months, and that of bilateral cleft lip is 6 ~ 12 months. There is no strict time limit for the first-stage repair of cleft lip, which is mainly divided into several time periods, pre-nursery, preschool, around puberty and finally adulthood. In order to reduce the psychological burden of patients, the sooner the repair operation is done, the better. However, due to various factors, many people will consider the second-stage repair in adulthood. For adult patients, the operation time can be decided at any time according to their own situation.
