Background: Chest wall reconstruction can be a challenge. The perfect material does not exist to restore chest wall stability. Synthetic materials have been the mainstay for reconstruction. Biological material use has increased. Recently, we initiated the use of a biosynthetic material for chest wall reconstruction that is composed of ovine-derived extracellular tissue matrix and monofilament polypropylene suture. Methods: We respectively reviewed all patients who underwent chest wall reconstruction with a biosynthetic material from January 2020 to June 2021. Results: Twenty-five patients underwent chest wall reconstruction. Median age was 35 years (range, 18 to 68); 64% were men. Indication for reconstruction was tumor resection in 10, chest wall defect after pectus repair in 7, radiation necrosis in 5, chest wall infection in 2, and lung herniation in 1. Infection was present in 28%. Median chest wall defect was 7 × 10 cm (range, 3.5 to 22.5 cm). Bioabsorbable bars were used in combination with the biosynthetic material patch in 15 patients (60%) and biosynthetic material alone in 10; 5 patients underwent myocutaneous advancement flaps. There were no operative deaths. Postoperative complications occurred in 6 patients (24%). Median hospital stay was 5 days (range, 3 to 14). Late complications occurred in 4 patients (16%). No patient had paradoxical motion, chest wall instability, or required biosynthetic material removal at a median follow-up of 12 months (range, 1 to 18). Conclusions: This novel biosynthetic material combines the benefits of biologic material and polymer reinforcement to provide a more natural chest wall reconstruction compared with mesh products made of synthetic material alone. Early results are promising in this first series in the literature.
