Background: Chimeric osteomyocutaneous flaps harvested from the subscapular artery system have been used in clinical practice. We describe the use of a novel circumflex scapular artery myocutaneous and/or vascularized scapular chimeric flap in a rat model and demonstrate optimal skin flap dimensions.
Materials And Methods: An 8 × 4-cm-rectangular skin flap based on the circumflex scapular artery flap was harvested, and the mean percentage of the surviving flap area and the necrotic area were calculated to be 71% ± 17.
