Lower Trapezius Myocutaneous Island Flap

• Resurfacing of the floor of the mouth and buccal region of the oral cavity and the tonsillar region of the oropharynx may be accomplished with many variations of regional and distant vascularized flaps. Our experiences in the use of 14 lower trapezius myocutaneous island flaps are described with respect to the unique application and suitability of this flap to resurface defects in these areas, as well as the contraindications, both relative and absolute, to the use of this particular method of resurfacing. In addition, the intraoperative technique and attendant problems, as well as postoperative complications, are presented. The overall advantages and disadvantages of this flap as compared with the more traditional pectoralis myocutaneous flap are outlined. It is our belief that because of the distinct qualities of this flap, including extended scope and flap thinness, this method of reconstruction merits consideration in the preoperative planning process.
