The condition is genetically related and is generally thought to be caused by overgrowth of the ribs and rib cartilage. The rib deformity leads to an imbalance in strength on both sides of the sternum, which in turn causes abnormalities in the sternum. The physiological effects on respiratory and circulatory function are also constant, especially in patients with combined scoliosis, and many of the lesions are progressive and therefore need to be actively corrected. Traditional surgical methods, including thoracic rib sinker and various thoracic reversals, require a large incision in the anterior chest, which seriously affects the aesthetics, and the patient suffers a lot of trauma and pain, slow recovery, easy infection, and a certain degree of poor orthopedic results or recurrence. Our minimally invasive correction of pectus excavatum is performed by making a 2-4 cm incision on each side of the chest wall. Through this incision, an adjusted plate is safely and precisely placed to press down the protruding chest wall, thus restoring the flatness of the chest wall. This procedure is effective for most types of pectus excavatum. It has minimal trauma, quick recovery, and excellent postoperative results.
