Funnel chest is currently a common congenital thoracic deformity disease, and some scholars have classified it as a cosmetic surgery. Minimally invasive NUSS surgery is one of the most widely performed surgical methods for the correction of funnel chest internationally. The surgery is done under the thoracoscope, which has many advantages such as less trauma, shorter operation time and faster postoperative recovery compared with traditional surgical methods. In recent years, our department has successfully carried out many cases of thoracoscopic funnel chest correction, and the results are all good, and the thoracic deformity is obviously corrected after surgery. The per capita operation time is about 1 hour, and the operation effect is immediate and basically does not leave scars, which has changed the lives of many patients and improved the self-confidence of teenagers in the process of interaction with others. Recently, the thoracoscopic correction of chicken breast is also being promoted gradually.
