Three to six months is a better time for surgery for babies with polydactyly, because the establishment of thumb function in babies starts around six months, and this is the time when babies start using their thumbs normally, and if we do it a little bit later in life, the time for the thumb function to build up slowly passes. It’s not that we can’t do it after that, but if nothing else, three to six months is better. Whether or not the baby can be operated on at three to six months depends on a few things: first, whether or not the anesthesiologist’s level of anesthesia is up to par; and second, how the baby is doing physically, whether or not there are any problems with the heart, and whether or not the baby’s weight is up to par. Once these two bases are in place, we can operate when the baby is three to six months old. In addition to the timing of the surgery, many parents are also concerned about the anesthesia for the surgery. For babies with multiple thumbs, we will use general anesthesia during the surgery. Upon hearing that general anesthesia is needed, many parents are concerned about whether it will affect the baby’s intelligence and development. In fact, a single short anesthesia will not affect the baby’s intelligence and development, so parents do not need to worry too much in this regard.
