Platysma myocutaneous flap revisited.

The platysma myocutaneous flap has seen limited application in the reconstruction of head and neck defects over the past decade. There are anatomical and physiological reasons for this. There has been an emphasis on the anatomical vascular supply and method of preparation of the platysma myocutaneous flap and its use in the oral cavity. This article emphasizes the use of this flap for reconstruction of defects of the base of tongue, hypopharynx, lateral pharyngeal wall, and supraglottis. The criteria for selection of the platysma myocutaneous flap as a method of reconstruction, and the limitations, are outlined. New variations of harvesting the flap based on randomized muscular support are described. Specific complications as seen in our group of patients add certain precautions in the use of the platysma myocutaneous flap.
