AN IMPROVED TECHNIQUE FOR DEVELOPMENT OF THE PECTORALIS MAJOR MYOCUTANEOUS FLAP

The pectoralis major myocutaneous flap is the most commonly employed muscle skin transfer used in soft-tissue reconstruction of defects of the upper neck and jaw region. This article presents conceptual and technical changes in the development of the pectoralis major myocutaneous flap that preserve a greater vascular pedicle and enhance the flap's arc of rotation. Data from 54 consecutive cases using this modified approach show a reduction in complications, a greater range of use, and consistent healing in radiated and nonradiated tissues without requiring sectioning or removing the clavicle or causing significant chest deformities. These modifications have produced a more predictable transfer compared with other reported techniques. © 1990.
