Flap surgery is a type of reconstructive surgery where a section of tissue, known as a flap, is moved from one part of the body to another. This flap includes skin, muscle, and sometimes bone or fat, and it retains its own blood supply. Flap surgery is commonly used to repair defects, reconstruct areas after trauma or cancer removal, and improve functional or aesthetic outcomes. The procedure involves carefully detaching the flap from its original site and securing it in the new location, where it will integrate with the surrounding tissues. This technique is crucial for enhancing healing and restoring normal function.
