Many parents do not know when is the best time to have surgery for babies with polydactyly. In fact, there are two points in time when polydactyly can be done, the first is before your baby learns to walk and the second is when he or she is about twelve years old. If the surgery is done when the baby is a few months old, it requires general anesthesia. If the surgery is done around the age of twelve, the child can already control himself very well, so local anesthesia is fine. Although polydactyly is not as conspicuous as polydactyly, many parents still want to operate before their baby learns to walk, mainly because they are concerned about the psychological impact it will have on their baby. Parents are most concerned about general anesthesia when the surgery is performed at a very young age. In fact, a single short period of anesthesia will not affect the baby’s intelligence or development, so parents can rest assured.
