Pectus excavatum is a deformity in which the sternum bulges forward and is the second most common chest wall deformity after funnel chest. It is mostly thought to be due to overgrowth of the rib cartilage and, like funnel chest, is genetically related, but the cause is not yet clear. In typical pectus excavatum, the lower and middle sternum and the root of the glabella protrude significantly forward, and the 4 to 8 ribs of cartilage on both sides are in a deep depressed groove parallel to the sternum; in atypical pectus excavatum, the sternum protrudes asymmetrically. It is mostly noticed after childhood. In general, there are few symptoms of cardiopulmonary compression in pheochromocystis, but in severe cases, recurrent upper respiratory tract infections and bronchial wheezing, poor activity tolerance, and easy fatigue can occur, making surgical treatment necessary. Most patients with pectus excavatum have no symptoms or no obvious symptoms, but when they grow up to adolescence, they will have psychological pressure on their distinctive chest and have inferiority complex, so they require surgery. 1.Traditional surgical methods include: ①Tipless sternal reversal; ②Sternal rib subsidence; ③Sternal reversal with vascular tip; but it will recur after surgery. 2.Minimally invasive thoracoscopic correction: similar to Nuss for funnel chest, correction of pectus excavatum is done by the mechanical action of steel plate. It is more effective for symmetrical and mild symptomatic corpus cavernosum, but there is still a certain recurrence rate after removing the steel plate. 3.Sternal rib fixation correction: It is our newly invented surgical method, which is suitable for heavier, or complex corpus cavernosum, and can achieve the purpose of no recurrence. The specific operation is to make a median incision in front of the chest, reveal the rib cartilage on both sides, cut the periosteum of rib cartilage, partially excise the affected rib cartilage within the deformity, make a transverse wedge osteotomy plasticity of the sternum to flatten the sternum, and then fix the sternal rib with titanium plate to form an anatomical correction of the thorax. And by appropriately elevating the position of the sternum during the surgery, it can solve the problems such as postoperative sternal compression of the heart that may occur in other surgeries. The results of the surgery are very satisfactory and can be achieved without recurrence.
