For the correction of funnel chest depressions, the older minimally invasive surgical approach is the NUSS procedure, while the newer minimally invasive surgical approach is the single-port procedure. Of these, NUSS is a third-generation technique and single-port surgery is a fourth-generation technique. For single-port thoracoscopic funnel chest correction, only a 1-2 cm incision is required on the right side of the child’s chest wall during surgery, and no incision is made on the left side of the chest wall. The surgery requires no penetrator, which reduces the damage to the body, and only one penetration of the titanium plate is required to hold up the depressed sternum without cutting off the sternum and ribs. The surgery takes a short time, about 10 minutes, and is minimally invasive, which is also more conducive to the surgeon in charge’s control of safety; moreover, the patient’s recovery after the surgery is fast, with no incision in the anterior chest and an aesthetically pleasing appearance, and he or she can participate in normal sports activities after discharge from the hospital. For asymmetric funnel chests, the surgical requirements are generally higher, that is, the complexity of the surgery is higher, but the effect is still possible for many relative asymmetries, but it is not as good as the effect of standard funnel chests, because the specific situation of each person is different, so we have to analyze the specific situation, that is, the postoperative situation of each person cannot be said to be the same. Some are ideal, some are not, but most of them should be good. In addition, in terms of funnel chest with flat chest, in fact, the effect of flat chest surgery is still quite ideal, but for some individual patients with complicated or ossified ribs, the effect is not so ideal, but the effect of most patients is still quite good.
