Abstract
The radial forearm free flap has proven versatility in head and neck reconstruction. It is superior to regional alternatives such as the pectoralis flap because it is thin, pliable, and predominantly hairless. A more recent application is the use of the folded forearm flap to replace both the skin and inner lining, simultaneously, in full-thickness cheek and lip defects. Nine such cases are presented in this report. Each patient had a recurrent lesion that had been reconstructed previously with local flaps, and all but one were treated with postoperative radiation therapy. The average size of the external defects after resection was 27 cm2, and of the intraoral defects, 18 cm2. All free flaps survived completely. The folded forearm flap solved the reconstructive problem for each patient in a single-stage procedure, providing good contour and a reasonable color match. The flap is easy to raise, has a long pedicle with large-diameter vessels, and has an acceptable donor site defect not associated with long-term morbidity.
