Syndactyly is a relatively common congenital malformation of the hands and feet, the cause of which is unknown but does include a genetic component. If there is a precedent for syndactyly on both sides of the parents’ family, there is a chance that a child will be born with syndactyly, but it is also a matter of chance, not a certainty. Is syndactyly scary or not? This is something we need to have a clear understanding of. First of all, we have to be clear that syndactyly is not an incurable disease, it can be corrected and improved through surgery, there is no need to panic too much about it. Some simple syndactyly can be sutured directly at the wound area during the syndactyly surgery, but more syndactyly will have skin loss during the syndactyly surgery, which is usually covered by skin grafting in the past. The donor area for skin grafting is usually chosen in the child’s tummy, which will not only cause new trauma to the donor area, but also have a certain necrosis rate in the recipient area. Even if the implant is successful, the recipient area will hardly be able to reach the state of native skin after the surgery, and there will be hyperpigmentation and decreased sensory function. We now mainly use artificial dermal induction technique in syndactyly surgery, which can induce the skin to grow on its own, without having to take skin from the child. The new skin will be very similar to the original one, and it will look and feel better after the surgery, without pigmentation and decreased sensory function, and the overall result is ideal.
