Objective To explore the clinical application effect and technical advantages of percutaneous suspension technique via sternal elevation device-assisted pectus excavatum (PE) correction. Methods Patients who underwent percutaneous suspension technique via sternal elevation device-assisted PE correction at West China Hospital of Sichuan University from July to August 2025 were consecutively enrolled, and their clinical data were analyzed. Results A total of 5 PE patients were included in the study, including 4 males and 1 female, aged 14 to 27 years, and the preoperative Haller index ranged from 3.44 to 7.65. Among them, 4 patients underwent PE correction assisted by percutaneous suspension technique via balance-shaped sternal elevation device, and one underwent PE correction assisted by percutaneous suspension technique via single sternal elevation device. All operations were completed successfully, with a significant expansion of the retrosternal space, smooth implantation of the steel plate, and no complications. The operation time ranged from 29 to 48 minutes, and the intraoperative blood loss was 2 to 5 mL. The patients recovered well after surgery, and the satisfaction rate with thoracic wall appearance correction was 100%. Conclusion The percutaneous suspension technique via sternal elevation device-assisted PE correction can safely expand the retrosternal operating space. This crucial expansion reduces surgical risks and optimizes the orthopedic outcome, underscoring its significant clinical value for minimally invasive treatment of PE.
