Many parents of babies with syndactyly have reflected this question, that is, how to cover the wound of the child’s syndactyly surgery? If the traditional method of skin grafting from the stomach is used, parents can’t bear to let their children add a scar, especially girls, who will be restricted in wearing clothes in the future, and if the child has a scarred body, the situation will be even more serious. If the child has a scarred body, the situation will be even worse. Moreover, the implant surgery itself has a certain chance of necrosis, and the child will face the possibility of a second operation, which is more painful. Even if the implant surgery is successful, it is difficult to achieve the original skin condition of the recipient area after the surgery, and there will be hyperpigmentation and decreased sensory function, which is also a concern of many parents: the child suffered so much, and the result after the surgery is still not satisfactory. The method we now use to cover the split finger wound is artificial dermal induction, which induces the skin to grow on its own without removing the skin from the child’s body. The skin that grows will be very similar to the original skin, and the postoperative appearance and sensory motility will be better, without pigmentation and sensory function loss.
