Whether or not a skin graft is needed for syndactyly depends on the type of syndactyly. If there is enough skin after the syndactyly is separated, it can be sutured directly and a skin graft will not be needed, but most syndactyly will result in a skin defect, which in the past has required a skin graft. The donor area for the skin graft is usually the baby’s tummy area, as the skin in this area is more pliable and soft, which makes it more suitable for skin grafting. There will be additional trauma to the tummy area after the surgery and the size of the scar will vary depending on the baby’s body type. If the baby has a scarred body, the scar will be more noticeable and will have a greater impact on the baby’s appearance. In addition to new scarring in the donor area, the recipient area of the implant will also experience hyperpigmentation, decreased sensory function, and a certain chance of necrosis. In order to avoid these effects of skin grafting, we now use artificial dermal induction technology to cover the wound, which can induce the skin to grow on its own, and the newly grown skin will be very similar to the original one, and the appearance and sensory function can reach a more ideal state, which is suitable for any type of syndactyly and syndactyly surgery.
