All thoracic deformity surgery has two purposes, one is to cure the disease and the other is cosmetic. For those patients whose deformity is less severe, or whose aesthetic requirements are more demanding, the cosmetic craving even comes first, so the incisions for their surgery must be chosen very carefully. Today’s popular NUSS procedures generally require three to four skin incisions, which are mainly used for thoracoscopic use and plate insertion. Although these incisions can be very short and do not cause too much damage, they can add to the aesthetic problems, so many surgeons have been trying to minimize the number of incisions. It is on this premise that the single-port NUSS procedure has emerged. The single-port procedure is performed as follows: a skin incision is made on the right chest wall near the mid-axillary line, followed by subcutaneous, intercostal, posterior sternal, contralateral extrapleural, and contralateral intercostal free tunnels, and then the plate is introduced. The entire procedure requires only one incision in the right chest wall, hence the name single-port surgery. Single-port surgery requires the assistance of a thoracoscope, but as anyone who has used a thoracoscope knows, it is not easy to see the surrounding structures clearly because of the presence of oozing blood as the lens passes between the tissues. In addition, even if the lens can be placed clearly in the above-mentioned channel, the instruments placed in the same hole will be extraordinarily “crowded”, which makes the operation very troublesome. In addition, the absence of instruments in other directions during the single-hole operation makes all operations difficult, especially for the operation through the mediastinum, and fatal complications can occur if the operation is not performed correctly. It can be seen that the excessive pursuit of aesthetics to reduce the number of incisions is a great technical risk. For the smooth implementation of the operation, the best choice is to take into account the safety of the operation and not to overly pursue the reduction of the number of incisions.
