Parents often ask me in the clinic when is the best time for their child to have surgery for syndactyly. They are afraid that the operation time is too late to affect their child’s result. Here I would like to give a unified answer, if your child has syndactyly and is in good health, it is usually better to have the surgery at around six months of age. Not too early, not too late, because some syndactyly is ring little finger, thumb index finger together, or fingers overlap each other, if not separated in time will affect the joints of the fingers, resulting in deformation, the further the child suffers. The outcome of syndactyly is related to the way the trauma is covered. If the traditional skin grafting method is used, the skin has to be taken from the child’s stomach, which will cause additional trauma to the donor area, as well as hyperpigmentation and decreased sensory function in the recipient area. Moreover, the skin implanted is not 100% viable, and there is a certain chance of necrosis. Nowadays, we mainly use artificial dermal induction technology to cover the wound, which can induce the skin to grow by itself, without having to take the skin from the child’s body. The new skin will be very similar to the original one, and there will be no hyperpigmentation or decrease in sensory function, so the appearance and function are more desirable.
