Never say no to a damaged muscle: The applications of previously damaged pectoralis major and latissimus dorsi muscles for chest wall reconstruction

The nondamaged latissimus dorsi and pectoralis major muscles are widely reported in the literature as being the most frequently used for chest wall reconstruction. In this study, we report a series of 9 patients with full-thickness chest wall defects who underwent reconstruction with previously damaged latissimus dorsi or pectoralis major muscles. Nine patients underwent chest wall reconstruction over a period of 3 years using previously damaged latissimus dorsi or pectoralis major muscles. The thoracic defect was posttraumatic in 3 patients and post-tumor resection in 6 patients. Three patients had previous radiation therapy. In 8 cases, the full-thickness chest wall defects were completely closed. The only failure encountered was in one patient who had a long lasting fistula. The proximal based island flap that was inserted into the tract showed good vascular supply and viability; however, it did not solve the clinical problem. Keeping in mind the basic rule of medicine ("Primum Non Nocere") and a thorough knowledge of the surgical anatomy of these muscles are essential for the successful application of these previously damaged muscles for chest wall reconstruction.
