It is a pathological change caused by the forward elevation of the sternum, accounting for 6-22% of chest deformities, with a male to female ratio of 3-6:1. Moderate to severe deformities can have adverse effects on the physiological and psychological development of patients and should be treated surgically at an appropriate age. It is generally believed that the onset of corpus cavernosum is mostly related to calcium and phosphorus metabolism, and patients often show progressive protrusion of the anterior chest wall in early adolescence, but clinically it is also found that there are families with coexisting funnel chest and corpus cavernosum, so a very small number of corpus cavernosum is also considered to be congenital, and only 10% of those who are found to have corpus cavernosum at birth have statistics, and there are a few secondary to congenital heart malformation and chest surgery (such as splitting the sternum through the anterior chest wall). surgery). Most pectus excavatum deformities are basically symmetrical, but there are a few asymmetrical types. Some scholars believe that premature surgery for pectus excavatum has the possibility of recurrence due to the softness of the bone, and that some mild pectus excavatum still has the ability to correct itself occasionally during development, so it is recommended that surgery be performed after puberty. The traditional surgical method of pectus excavatum is basically based on the so-called “sternal sinker”, while different methods are used according to the characteristics of each type. However, all of them require transverse or longitudinal incision in the middle of the chest to free both sides of the soft tissue of the chest wall and the pectoralis major muscle; subperiosteal stripping to remove multiple pairs of deformed rib cartilage bilaterally, cutting off the middle part of the sternum or making incomplete osteotomy at the proximal end according to its different anatomical shape, fully loosening the sternum to restore straightness; sinking the sternal ribs to restore the normal thoracic contour, removing overgrown rib cartilage after sinking and suturing the periosteum. If the sternum is unstable, a kyphotic pin can be placed transversely or longitudinally within the sternum to fix it to the chest wall. Bilateral pectoralis major muscles are pulled together and sutured in front of the ribs to prevent rebound of the sternum. Compared with traditional surgery for correction of pectus excavatum, minimally invasive surgery for correction of pectus excavatum does not require a large incision in the anterior chest wall, the incisions located on both sides of the chest wall are small and concealed, and there is no need to cut and extensively free the muscles of the chest wall, and no need to cut or remove any rib cartilage or sternum, thus avoiding the destruction of the bony chest wall structure by traditional surgery, and maintaining the extension, flexibility and elasticity of the chest for a long time, especially no surgical scar on the anterior chest wall, which is one of the most This is one of the most important advantages. This procedure can be performed more safely because it takes less time, has less bleeding, and has a faster recovery, resulting in significantly less surgical trauma. The incidence of pneumothorax, pulmonary atelectasis, and postoperative paradoxical breathing, which are complications of traditional orthopedic surgery, can also be reduced in minimally invasive surgery because the destruction of the bony chest wall structure by traditional surgery is avoided. Minimally invasive surgical treatment has fewer intraoperative and postoperative complications and has the advantage of being minimally invasive and aesthetically pleasing. However, specific surgical indications should be selected individually according to the patient’s age and type of corpus cavernosum. Patients with good chest wall compliance, symmetrical, basically symmetrical, mildly asymmetrical or localized anterior protrusion without obvious depression of the corpus cavernosum are suitable to choose minimally invasive surgery. However, patients with hard bones and poor chest wall elasticity at older ages; patients with significant local depressions and heavy rotation of the sternum in addition to the protruding chest wall; patients with high thoracic stenosis that squeezes the heart and lungs and seriously affects the cardiopulmonary function, and patients with other comorbidities that may be unsuitable for minimally invasive surgery are not suitable for minimally invasive surgery in my opinion.
