On the Internet, in the clinic and in the ward, we often meet families of children with congenital anomalies who ask when is the right time to operate? Here, we only talk about the choice of surgery time for general congenital malformations, such as syndactyly, polydactyly, short finger malformation, etc. The following two aspects should be taken into consideration when choosing the time of surgery: 1. The child should develop a little bit and grow up, so that the risk of surgical anesthesia is reduced and the difficulty is reduced, which is also beneficial to the postoperative care of the child. 2. To prevent the presence of deformities from causing psychological shadows to the child, so the surgery should be performed before the child understands, at least before the child starts kindergarten. Considering the above two points, the best time to operate is at the age of 1.5 years (18 months).
