The pectoralis major muscle in head and neck reconstruction.

From June 1980 to June 1985 51 pectoralis major muscle flaps have been used for one-stage reconstruction of extensive defects in the head and neck following cancer surgery. The pectoralis major muscle was used as a myocutaneous flap on 28 occasions, as a muscle covered with split thickness skin on 17 occasions, and as a muscle-only flap six times. The muscle, in its various forms, was used for reconstruction of the pharyngooesophageal segment, the tongue, floor of the mouth and oropharynx, to replace the skin of the face and neck, and to provide a well vascularized recipient bed for a split-rib graft, used to replace a defect of the anterior arch of the mandible. Many of the problems associated with the use of a pectoralis major myocutaneous flap can be avoided by the judicious use of a muscle flap on its own or covered by a split thickness skin graft.
