Simple pectoralis major myocutaneous advancement flaps for closure after sternal wound dehiscence

Abstract

Between October 1994 and March 1996, 14 consecutive patients with a wound dehiscence after median sternotomy for cardiac surgery were treated with pectoralis major myocutaneous advancement flaps. After thorough sternal wound debridement, the sternal edges were contoured to create a shallow defect. This was to enable the obliteration of dead space between the mediastinum and the flaps. The pectoralis muscle was then elevated off the chest wall, its humeral attachment, the thoraco-acromial pedicle and the connection with the skin were left intact. Next, the bilateral myocutaneous flaps were advanced medially and approximated to each other in the midline. The mean operation time was 140 min and the mean follow-up time was 10 months. Four patients developed minor complications. The advantage of this technique is its simplicity and the reduction in mean operation time.
