The Wang procedure, named after Director Wang Wenlin from the Second People's Hospital of Guangdong Province, is a surgical method for correcting pectus excavatum. Traditional minimally invasive techniques for correcting pectus excavatum, such as the Nuss procedure or its modifications, involve placing a metal bar under or behind the sternum, forming an arch to lift the depressed area, similar to a traditional arch bridge. In contrast, the Wang procedure positions the metal bar on top and in front of the sunken sternum, and then uses stainless steel wires to suspend the deformed sternum forward and upward, transforming the traditional arch into a modern cable-stayed bridge, thus suspending the depressed chest area.
