Major tenets in the reconstruction of the anterolateral chest wall include preservation of structural stability and function and coverage of the mediastinal contents. To reach these goals, a rigid support has been advocated by several authors. We describe a patient with extensive anterolateral defect after sternocostal resection of chondrosarcoma. Successful reconstruction was performed by using three metallic transverse plates and an omental flap wrapped onto the plates. This method simplifies reconstruction in comparison with previously described techniques concerning complete solid coverage and leaves several options intact in the event of future recurrences.
