Skin flaps are a type of reconstructive surgery that uses nearby skin and underlying tissue to cover an area after skin cancer removal. The flap of skin is rotated or transposed to the defect, preserving its blood supply, and allowing it to grow into the new area. Skin flaps are typically used for larger skin cancer defects and provide a more natural-looking result than skin grafts. The success of skin flaps depends on the location and size of the skin cancer and the overall health of the patient.
