title: An innovative method of reconstruction of large skeletal chest wall defects.
abstract: The reconstruction of large skeletal defects of the chest wall is considered complex and difficult. A simple technique for this repair, using polymethylmethacrylate ribs that are prefabricated in a prosthodontic laboratory using heat cure polymer, is presented. These ribs are used as bone substitutes while reconstructing the chest wall defect. The prefabricated polymethylmethacrylate ribs have been used to reconstruct the large chest wall defects after resection of chest wall tumors in three patients. There was risk of severe paradoxical movement of the chest wall without the skeletal defect reconstruction. In all of the cases, there was no need for postoperative mechanical ventilation and there was no paradoxical movement. Cosmetically, it was highly satisfactory. In one patient, the stainless steel wire caused a sinus after 1 year of reconstruction, requiring removal of the wire and the rib, but it did not compromise the stability of the chest wall. We conclude that reconstruction of large chest wall defects with prefabricated polymethylmethacrylate ribs is simple, cost-effective, and easy to plan and execute.
