The radial forearm flap has proved to be a reliable free flap for intraoral reconstruction after major head and neck ablative surgery for cancer. In contrast to the myocutaneous flap, it is thin and flexible, and as a result, it is better suited to conforming to the irregular surface which remains over an intact or restored mandible. A criticism of both techniques however, is that while the flap effectively fills the defect, it serves as an insensate reservoir in which food and saliva can collect. A modification of the reinnervated radial forearm free flap is presented, with discussion of its use in three patients, following extensive resection of the floor of the mouth and tongue.
