[Objective] To introduce the surgical method and preliminary clinical effect of the modified continuous skin stretch technique to treat large area skin defects.[Method] Seven patients with large-area skin defects were treated with modified continuous skin stretch technique. Two Kirschner wires are inserted into the upper and lower wound edges on both sides of the long axis of the defect wound respectively, and the Kirschner wires are pulled oppositely, and the exposed part is tightened and knotted with two double strands of silk thread, so that the skin edges on both sides of the wound are moderate.Perform moderate stretch every day. When the edges of the wound on both sides of the wound can be aligned, remove the device and use a horizontal mattress to suture the skin.[Result] All 7 patients were operated successfully, the wounds were closed at stage I, and no skin grafts or flap repairs were performed. The wound healing time was 18 to 36 days, with an average of 28.1±6.8 days. All patients were followed up for half a year after the wounds were healed, and there was no abnormal skin sensation and function at the wound edge.[Conclusion] This modified continuous skin stretch technique is an effective method to treat large areas of skin defects.
