The trapezius myocutaneous flap

The three trapezius myocutaneous flaps remain valuable adjuncts in head and neck reconstructive surgery. Overall, the lower vertical trapezius flap has the most versatility and reliability, and the least morbidity. There are several advantages of this flap compared to the pectoralis myocutaneous (PMC) flap. It has a thin vascular pedicle, and thus does not add excessive bulk to the neck, as the PMC can. Also, the skin island has less subcutaneous tissue and therefore more pliability than the PMC, which is a definite advantage for oral cavity and oropharyngeal defects. The trapezius flap generally has less hair than the PMC flap, and the donor scar is better hidden.
