Abstract:Introduction: Funnel chest deformation (FCHD) is the most common malformation of the chest. This anomaly appears as the cosmetic and functional disorders of the cardiovascular and respiratory systems. Its main characteristic feature is tendency to progression, closely linked with the growth and age of children. Purpose: To analyze results of surgical treatment at the children with FCHD, using minimally invasive method of thoracoplasty. Materials and methods: The research group included 21 children with FCHD at the age from 4 to 17 years. Symmetrical shape of deformation was revealed in 14 patients (66.6%), the asymmetric shape was revealed in 5 (23.8%) patients, the FCHD -in 2 children (9.5%). Preoperative examination included: routine clinical laboratory research, spirography, electrocardiography, echocardiography, chest radiography in the frontal and lateral projections and computed tomography. All patients underwent thoracoplasty with using method D. Nuss. Results: The period of supervision covered from 6 months to 4 years after surgery operation. Good results were obtained in 17 (80.96%) cases; satisfactory -in 3 cases (14.28%), unsatisfactory -in 1 case (4.76%). Conclusion: Surgical treatment of FCHD with using innovative in Ukraine method of retrosternal metal fixators -is vital importance direction in thoracoplasty, having numerous advantages, compared with resection techniques, as well as minimally invasive and a good cosmetic effect.
