Clinical reappraisal of the segmental pectoralis major turn-over flap for coverage of the local mediastinal wound.

The viability of a long and narrow pectoralis major turn-over flap based on one intercostal muscle perforator was supported by the result of our cadaveric injection study. This flap preserves the muscular strength and aesthetic contour of the anterior axillary line, and is attractive for reconstruction of the mid-sternum.
