Is scar flap grafting effective?

Generally speaking, scar flap transplantation refers to flap transplantation surgery. Flap transplantation is usually effective, especially suitable for repairing large-area scars, deep tissue defects, or scars accompanied by functional impairments. A detailed explanation is as follows:

The principle of flap transplantation involves transferring skin and subcutaneous tissue bearing a vascular pedicle to the defect area after scar excision. The blood supply from the body ensures the survival of the transplanted tissue. This procedure not only fills the tissue defect but also improves local blood circulation, promotes wound healing, and restores skin elasticity and function.

Compared with simple scar excision and suturing, flap transplantation provides a greater volume of tissue to cover complex wounds and reduces the risk of recurrent contracture. It is especially effective for scar repair on functionally important areas such as the face, hands, and feet. However, this surgical procedure is more complex, requiring precise vascular anastomosis, and leaves a new scar at the donor site. Postoperatively, complications such as flap swelling and pigmentation may occur, necessitating secondary revisions. The outcome also depends on the scar's location and size, as well as the patient's individual healing capacity; therefore, this method is unnecessary for small, superficial scars.

Therefore, flap transplantation is effective for repairing specific types of severe scars, but strict indications must be followed. An experienced physician should evaluate the patient and formulate a treatment plan. Postoperative anti-scar therapy and functional rehabilitation are also necessary to maximize the repair outcome.
