latissimus dorsi flap
Pronunciation: la-TISS-ih-mus DOR-sye flap
A pedicled myocutaneous flap using the latissimus dorsi muscle and overlying skin for breast reconstruction or other large defect coverage.
Full Definition
The latissimus dorsi flap is a versatile reconstructive option that utilizes the broad, flat latissimus dorsi muscle from the back, along with overlying skin and subcutaneous tissue. This pedicled flap maintains its blood supply through the thoracodorsal vessels and can be rotated to the anterior chest for breast reconstruction following mastectomy. The flap provides reliable coverage for large defects and can be combined with tissue expanders or implants. While it offers good aesthetic results, it may result in some functional loss of shoulder adduction and back contour changes.
Usage
Usage note: Always specify whether the flap includes muscle only or is myocutaneous when documenting procedures.
