The Functional Pectoralis Major Musculocutaneous Island Flap in Head and Neck Reconstruction

We describe our experience with the true island pectoralis major musculocutaneous flap in patients with high-volume defects for whom free-tissue transfer is unsuitable. Our operative technique is presented. We have modified the method of making a true island of the pectoralis major musculocutaneous flap on a muscle-free pedicle as first described by Wei et al. in 1984. This maintains maximal donor-site muscle function and facilitates closure of the donor-site defect. We present our results in 24 patients, in whom the flap has proved to be robust and reliable. The flap's advantages in terms of increased pedicle length, wider arc of rotation, decreased pedicle bulk, and improved cosmesis of the reconstruction are discussed.
