This baby was born with syndactyly and was already 4 years old when he came to us, far beyond the recommended age for syndactyly surgery. The parents said that after the birth of the child, the family began to consult everywhere on surgical options, but the hospitals they visited all said that the skin had to be removed from the stomach and implanted on the hands, and the elderly in the family were adamant that they would not allow the surgery, and they couldn’t bear to let the child suffer, so there was a delay. In the past few years, we have asked many doctors, but we have not found a suitable solution to avoid skin grafting completely. Seeing that the baby is getting older and older, the family is very anxious, and they are afraid that the child will have low self-esteem because of the syndactyly in the future. It is true that most of the syndactyly surgery involves skin grafting, because after syndactyly, the amount of skin will be deficient and the skin tension will be increased, so few of them can be sutured directly, and most of the cases need to be covered by skin taken from other parts of the body, that is to say, skin grafting technique is used to ensure that the shape of the finger body and the blood supply is good after the surgery. Although skin grafting can solve the problem of skin loss in syndactyly surgery, it also has certain disadvantages. Skin grafting will cause new trauma and scarring in the donor area, which is better for boys, but has a great impact on girls, who will be limited in their choice of interests and clothing in the future. Since the skin is taken from the stomach and implanted on the hand, the skin in the recipient area will not be able to achieve the same effect as the original skin after the surgery, and there will be hyperpigmentation and a decrease in sensory function. In order to avoid these problems, we now use the artificial dermis-induced skin-less implantation technique in our syndactyly surgery, which uses artificial dermal material to induce the skin to grow on its own, instead of removing the skin from the child’s body, so that there is no new trauma or scarring, and the impact of the surgery is minimized. The new skin induced by the artificial dermis will be very similar to the original skin, and there will be no hyperpigmentation or loss of sensory function, and compared with the implantation of the skin, the postoperative result is overall more satisfactory.
