Although the old method has had very mature and stable results, in view of the fact that there are always many parents who have expressed the wish to merge fingers without skin implants. Starting from the second half of last year, we gradually implemented the modification of the parallel finger (toe) finger (toe) Pu-plasty. Based on my original V-tip flap, I combined the advantages of the pentagonal flap of Director Gao Weiyang to design a new finger (toe) webbing method, a bipedal flap, which made it possible to separate the parallel fingers and toes without skin implants. However, for the sake of caution, the method was started on the syndactyly of the foot, and has been applied in the syndactyly of the foot for nearly half a year, and has now gained more mature experience, and has been fully applied in the syndactyly of the hand since this year. However, it should be noted that the application of this method does not allow all the syndactyly to be done without implants. In particular, I emphasize the aesthetic appearance of the finger and will not force the wound to be sutured for the sake of non-implantation, which may cause postoperative scar contracture and finger flexion. Small skin grafting is usually needed at the end of the finger, especially after the separation of the finger with tightly attached nails. However, since the root of the finger usually does not require skin grafting, the skin area can be very small. Instead of choosing the groin, a small piece of skin can be taken from the ulnar side of the wrist or the inner ankle of the foot, and the wound can be sutured to match the natural skin pattern of the wrist and ankle, so that the scar is not easily visible. Also, fingers that have curvature themselves are not suitable for this method. It is important to emphasize that I can’t say that the results are significantly better than the old method I used. Although there is no skin graft or a small area of skin graft, there is an additional dorsal scar, which is more pronounced on the dorsal side of the finger and toe. This is actually a common problem with all current techniques of juxtaposed finger separation without skin grafting, which is the inevitable result of using the dorsal skin to form the finger web and to close the trauma on the lateral side of the finger. Thus, there are advantages and disadvantages to each technique, skin grafting or no skin grafting. In the juxtaposition of the foot, I would recommend the new method without or with less skin grafting because the scar on the foot is not conspicuous. However, for the hand syndactyly, since both methods have their own advantages and disadvantages, I will inform the parents and let them decide on their own choice. I do both methods.
