Funnel chest is the most common congenital thoracic deformity, which is characterized by a sunken anterior chest wall centered on the lower and middle sternum, shaped like a funnel, and worsens with growth and development. The sunken sternum compresses the heart and lungs and affects the development of organs, resulting in respiratory infections, decreased activity endurance and other symptoms, causing great psychological stress to the child and parents. Surgical correction is the only option to improve the condition. In the past, sternal reversal, rib cartilage excision or severance were used, which required extensive separation of the subcutaneous and muscles and severance of the sternum and ribs. The operation takes a long time, is traumatic, bleeds a lot, has obvious scars, and causes postoperative thoracic developmental disorders and chest wall sclerosis. Over the years, we have treated more than 400 cases of congenital funnel chest and recurrent funnel chest by thoracoscopic minimally invasive funnel chest correction (NUSS surgery), with a success rate of 100% and very satisfactory results, ranking first in China. In the past two years, based on the successful NUSS surgery, we have further simplified the operation and pioneered the ultra-minimally invasive funnel chest orthopedic surgery, which applies the ultra-minimally invasive funnel chest plate independently developed by the Department of Thoracic Surgery of Shanghai Xinhua Hospital to further shorten the operation time, improve the operation effect and success rate, reduce the operation injury and postoperative complications, reduce the postoperative pain, reduce the operation cost, shorten the hospitalization, and expand the operation indications. We have developed a series of minimally invasive funnel chest plates. Compared with the traditional NUSS surgery, minimally invasive funnel chest correction avoids the huge lacerations to the soft tissues of the chest wall caused by intraoperative plate flipping; it is easier and faster to remove the plates and avoid secondary damage to the intercostal muscles caused by plate removal; it truly provides individualized treatment and is very satisfactory for the correction of asymmetric funnel chest. Patients’ postoperative pain is greatly reduced, the duration is shorter, they can turn over and lie on their sides, the operation time is halved compared with the original, no chest tube is placed, they can be discharged 2 to 3 days after the operation, and the cost is about 20% less than before. The application of ultra-minimally invasive funnel chest orthopedic surgery marks our achievement of international advanced level in the treatment of funnel chest.
