free flap

A free flap in medicine is a type of reconstructive surgery where tissue, including skin, fat, and sometimes muscle, is moved from one part of the body to another to cover a defect. Unlike a simple skin graft, a flap retains its own blood supply, which is reconnected to blood vessels at the recipient site. This ensures the tissue survives and can be used to cover exposed bone or tendons, or to reconstruct areas like a nose. This technique is particularly valuable when significant tissue loss occurs due to trauma or surgery, and local tissue is insufficient. The procedure aims to restore both form and function, leading to good cosmetic and functional outcomes.123
