Lengthening the pedicle of the rectus abdominis myocutaneous flap for repair of upper chest and neck defects
2017
INTRODUCTION The aim of this study was to investigate whether the pedicle of the rectus abdominis flap can be lengthened by resecting the inferior costal cartilage segments or associated muscle when repairing upper body defects. A formula was generated that calculates the expected increase in pedicle length. METHODS Thirty patients underwent computed tomography. The width and thickness of the third to seventh inferior costal cartilage segments as well as the width of the respective intercostal spaces were recorded. Four patients underwent reconstruction of an upper body defect with the relevant flap. RESULTS The expected mean increases in pedicle length were 4.07cm (standard deviation [SD]: 0.31cm) and 4.63cm (SD: 0.54cm) following resection of the left and right sides respectively of the seventh inferior costal cartilage segment, 7.99cm (SD: 0.49cm) and 10.82cm (SD: 0.23cm) following resection of the left and right sides respectively of the sixth and seventh inferior costal cartilage segments while resec...
