Flap surgery is a type of surgical procedure used to repair or reconstruct damaged tissues. It involves moving a section of healthy tissue, known as a flap, from one part of the body to another. This technique is often used in cases of trauma, cancer removal, or congenital defects, helping to restore both function and appearance. During flap surgery, the flap may include skin, muscle, or fat, and it is carefully connected to its original blood supply to ensure proper healing. Surgeons assess the best type of flap based on the patient's needs and the location of the injury, aiming for optimal results in recovery and aesthetics.
