Suction cup treatment is effective for patients with mild funnel chest, but basically has no therapeutic effect on patients with severe disease. Most patients with a mild degree of funnel chest deformity do not require any special treatment, and most of them can be corrected on their own as they grow older. Symptoms of funnel chest compression in infancy are often overlooked, and it is important to be aware of the presence of respiratory obstruction in the patient. Severe cases of funnel chest deformity should be treated with timely surgery, and the main treatment modalities are sternal lift, sternal reversal, and banded sternal reversal. Surgery is best performed between the ages of 2 and 5 years, and early surgery has a better prognosis. If funnel chest is diagnosed, it should be treated under the guidance of professional physicians in time, and should not be treated without authorization, so as to avoid delaying the condition. Pay attention to rest on weekdays and avoid overwork.
