Funnel chest is a congenital and often familial condition. It is a progressive lesion that may be present at birth, but often becomes more obvious to parents only after a few months or even years. Should I have surgery if I have a funnel chest? For small children, because of the soft bone quality and easy deformation of rib cartilage, the temporary deformation of chest wall will be caused when the child breathes hard and cries, and for children within two years of age due to weakness, soft bone quality and easy deformation of rib cartilage (rickets active period), as long as there is no obvious cardiopulmonary dysfunction, conservative treatment should be given first, and appropriate calcium supplementation, nutrition and appropriate outdoor activities can restore normal appearance on their own. Chest wall appearance. If the funnel chest affects the cardiopulmonary function and has a mental burden, the funnel chest should be treated by surgery. Most scholars believe that the better age for surgical correction is 7 to 12 years old. As long as the deformity is obvious, surgery should be performed immediately regardless of the age, instead of waiting until there are serious clinical symptoms, and the younger the age, the better the treatment effect and the smaller the scope of surgery required. Indications for surgery for funnel chest treatment: Progressive worsening of symmetric funnel chest, Haller CT index ≥ 3.25 and/or funnel chest leading to respiratory symptoms, abnormal cardiopulmonary function. (1) Haller index > 3.25 on CT. (2) Pulmonary function suggesting restrictive or obstructive airway pathology. (3) Abnormalities such as incomplete right bundle branch conduction block and mitral valve prolapse were found on ECG and echocardiography. (4) Progression of the malformation and combination of significant symptoms. (5) The deformity in appearance is intolerable for the sick child.
