Forearm Retrograde Island Flap Removal

Skin flaps are also called pedicled skin grafts. A modern view is that a skin flap is a tissue block composed of skin and subcutaneous tissue that can be transferred from one part of the body to another. During the transfer process, one or two pedicles need to be connected, or they can be temporarily disconnected, and then anastomosis is performed after transplantation. The flap's blood transport and nutrition relied on the pedicle supply early on. When the flap heals at the skin graft, about three weeks later, a new blood circulation system is gradually established. At this time, the pedicle can be severed, and the flap transplantation process is over. Sometimes, some flaps can also be constantly pedicled, such as partial rotation flaps or advancement flaps. After the flap is transferred, due to the full-thickness skin and rich adipose tissue, its shrinkage is much smaller than that of the free skin graft, and it can withstand external friction and maintain the original color before the flap transfer. The skin flap can cover deep wounds and protect deep tissues during cosmetic plastic surgery. It is an ideal material for cosmetic plastic surgery of organs and body shapes. Such as nose reconstruction, correction of lip deformity, correction of eyelid eversion, ear reconstruction, breast reconstruction, penis reconstruction, etc. are particularly applicable. In scalp and face reshaping, flap transplantation, especially partial rotation flap transfer, is also indispensable for repair after scar removal and repair of scalp defects. Due to the small supply area of ​​facial flaps, it is not suitable for large-scale cosmetic surgery. For large-scale facial defects (such as after large-scale hemangiomas, large moles, or large scar removal), cosmetic surgeons They can also use distant skin flaps for plastic repair. Thoracic triangle flaps and neck flaps are often used. This kind of flap has several advantages for facial cosmetic surgery: first, the repair area is large; second, the flap area is hidden, and scars after healing will not be easily exposed; third, the skin area of ​​the flap is close to the facial skin, and the face After shaping, the skin color is close or not much different. However, plastic surgery of the distant flap is more complicated and time-consuming, and the appearance of the postoperative bloating is a bit bloated, and sometimes a second fat removal procedure is performed.
