The topic of skin grafting comes up in most syndactyly syndactyly surgeries. In the past, skin grafting was usually done by taking a piece of skin from the baby’s tummy to cover the trauma from the syndactyly surgery. This creates two problems: 1. The donor area, that is, the baby’s stomach area, will have new trauma and scarring, which will not be very aesthetically pleasing to the eye, and if the baby is scarred, the situation will be worse. 2, the recipient area will have some loss of sensory function and hyperpigmentation problems, and there is a certain chance of necrosis. Now we almost do not do this kind of skin grafting, basically are using artificial dermal induction technology to cover the trauma, it can induce the skin to grow on its own, the new skin will be very similar to the original, the trauma will only leave a relatively hidden linear scar, whether it is the sensory function or the appearance of the overall effect of skin grafting have obvious advantages.
