Funnel chest requires different treatment programs depending on the degree and usually cannot be corrected on its own. Funnel chest is a boat-shaped or funnel-shaped deformity in which the sternum and ribs are concave inward and backward, the pathogenesis of which is still unclear, and the clinical manifestations and treatments are different according to the degree of severity. If the degree of funnel-shaped chest deformity is mild, it does not need special treatment, and can be corrected by itself as it grows older. If the deformity is serious, it will affect the physical development and respiratory and circulatory functions, and also cause psychological burden to the patient, so it should be treated by surgery. The timing of surgery is best at the age of 2 to 5 years, and early surgery is more effective. There are three commonly used traditional surgical methods, which are sternum lifting, sternum flipping, and banded sternum flipping. In recent years, with the development of minimally invasive technology, minimally invasive funnel chest correction has been widely used in the clinic, and the surgical effect is satisfactory and less traumatic. If you suspect that you have funnel chest, you should consult a doctor as soon as possible, and you can confirm the diagnosis and assess the severity of the chest CT examination, and formulate a treatment plan under the guidance of a professional doctor, and do not listen to folk remedies to correct the problem on your own.
