Platysma myocutaneous flap: use for intraoral reconstruction.

Twenty patients were treated for intraoral epidermoid carcinoma with a single-stage reconstructive technique using a myocutaneous flap based on the platysma muscle. This flap carries on its distal tip a portion of isolated cervical skin to be used for intraoral replacement of the resected tissue. The superior vascular pedicle, the submental branch of the facial artery, was used. The platysma skin flap will survive if the blood supply from at least one region is preserved. In addition, it may be beneficial to include the external jugular and/or the communicating veins in the flap. Only three minor complications were seen and healed spontaneously. The flap has proved to be highly reliable and has significant benefits over many other techniques commonly used for head and neck reconstruction.
