There is no self-cure for funnel chest. Funnel chest is the most common chest wall deformity, characterized by a sunken sternum. When the condition is severe, it can compress the heart and lungs, leading to dyspnea and other decreased cardiopulmonary functions. The disease cannot be cured on its own. Mild degrees generally do not require special treatment, while moderate to severe deformities are mainly treated with surgical treatments such as sternum lifting, sternum flipping, sternum flipping with tibia and minimally invasive funnel chest correction. Surgical treatment of funnel chest can effectively correct the deformity, improve the patient’s respiration and cardiopulmonary function, reduce the psychological burden, with high patient satisfaction and good long-term results. One week after the surgery, patients can do standing training against the wall, 3 times a day, 30 minutes each time, and walk with head up and chest out and stomach in, which will help the recovery. It is recommended that when the condition of patients with funnel chest reaches a moderate to high level, they should go to the hospital for surgical treatment in a timely manner, and they need to pay attention to regular follow-up after the operation to check the correction of the deformity.
