Funnel chest is a congenital chest wall deformity in which the sternum, rib cartilage and part of the rib cage are sunken into the spine to form a funnel shape, which can compress the patient’s heart and lungs and directly affect the patient’s cardiopulmonary function. Therefore, patients with funnel chest should receive active treatment. Surgical correction is the only effective method to treat funnel chest. Traditional open-chest orthopedic surgery is very traumatic, with many complications, obvious postoperative scars and high recurrence rate, and has been gradually replaced by minimally invasive Nuss orthopedic surgery. Minimally invasive Nuss orthopedic surgery can be completed by making small incisions in the bilateral axillae, and then placing a support device to hold up the anterior chest wall. The procedure is less invasive, shorter, safer, more aesthetically pleasing, with smaller and more concealed scars, and has a much better outcome than the traditional procedure, and the brace can be removed three years after the Nuss procedure, which is also safe and fast. Our thoracic surgery department is the first unit in South China to perform minimally invasive Nuss correction for funnel chest, and has successfully performed Nuss correction for more than 800 patients with funnel chest, accumulating rich clinical experience in surgical techniques, especially for complex, asymmetric, recurrent, very severe and adult funnel chest, etc. The follow-up results are satisfactory.
