Introduction: Children have signs of chronic hypoxia, metabolic disorders. decreased appetite. Against this background, surgical treatment, which includes reconstruction of the chest, presents a certain risk. Based on these provisions, special attention was paid to the preoperative preparation of patients. Objective: 1) Optimization of preoperative preparation and methods of surgical correction of funnel chest pectus excavatum( PE); 2) Improvement of postoperative management of sick children with funnel chest. Method: We operated 44 sick children in our hospital who were admitted to the surgical department with a diagnosis of PE. After preliminary examination, these patients underwent surgical correction of the chest according to Bairov and Ravich-Gross. Results: In sick children aged 3-6 years after the Ravich-Gross operation, compared with the Bairov operation, the intensity of the pain syndrome was expressed as according to the VAS scale (7.55 __ampersandsignplusmn; 0.24 versus 6.0 __ampersandsignplusmn; 0.52 points, p __ampersandsignlt;0.01) and on the VRS scale (2.2 __ampersandsignplusmn; 0.12 versus 1.5 __ampersandsignplusmn; 0.18 points, p __ampersandsignlt;0.01). This plate provides more reliable fixation of the SCC than Marshev__ampersandsignrsquo;s tire, is convenient to use. Conclusion: The methods of thoracoplasty with the use of external fixators are acceptable for children of the younger age group since these methods are safer in the long term than a metal plate inside the chest due to excessive motor activity of children. Good treatment outcomes are observed mainly in children operated on at the age of 3-6 years.
