Cockscomb is divided into congenital and acquired, and the latter is mostly due to nutritional disorders, mostly seen in early childhood, and is a manifestation of rickets. Premature surgery of chicken chest has the possibility of recurrence due to the soft bone, and the acquired chicken chest occasionally has the ability to correct itself during the development. Therefore, for children with rickets under 3 years old, anti-rickets treatment should be actively given, including dietary therapy, vitamin D therapy, and calcium supplementation if necessary, and generally mild rickets will gradually disappear with physical growth. For children after the age of 3, most of them have the sequelae of rickets, and the treatment with calcium and vitamin D is not effective, so the purpose of correcting the deformity can also be achieved by using special brace to compress the raised chest and maintain it for a certain period of time. In adolescence, the brace often fails to achieve the orthopedic purpose because of the gradual hardening of the bone. In addition, older patients often have low self-esteem and lack of self-confidence, which affects their psychological health, and they are reluctant to swim and participate in outdoor activities because of their hunchback when walking and sitting. The abnormal posture and lack of exercise will aggravate the deformity. Therefore, for patients of older age and those with cardiopulmonary effects, surgical treatment is available. Traditional surgery: Since the impact of pectus excavatum on cardiopulmonary function is less than that of funnel chest, and since pectus excavatum can be corrected by bracing at younger ages, surgical correction of pectus excavatum developed later than that of funnel chest. In the past decades, sternal sinker and its modifications have been used. Sternal subsidence is generally performed by making a longitudinal or transverse incision of 8-15 cm at the chest wall projection, freeing the muscle, exposing the deformed sternum and rib cartilage, cutting and freeing the deformed rib cartilage membrane, cutting the rib cartilage in the middle, fully loosening it, subsiding the sternal ribs, removing the overgrown rib cartilage after subsidence, and suturing the ends to correct the deformity; if the subsidence is unsatisfactory, incomplete osteotomy can be performed on the proximal end of the sternum. In addition to the disadvantages of a large median incision, freeing the muscles, and severing the rib cartilage and sternum, the greatest disadvantage of this procedure is the reduction of the volume of the thoracic cavity after removal of the excessively long rib cartilage. Minimally invasive surgery: Nuss first introduced the boneless resection correction method for pediatric funnel chest in 1998. in addition to the advantages of small and hidden incision, short operation time, less bleeding, fast recovery, no free chest wall muscle flap, no rib cartilage or sternum removal, etc., the Nuss procedure is most prominent for its ability to maintain long-term chest extension, expansion, flexibility and elasticity. Because the Nuss procedure is a minimally invasive, easy-to-grasp technique, it is rapidly gaining acceptance among surgeons around the world and has now become the standard and preferred procedure for the treatment of funnel chest. The minimally invasive sternal sinker, which is based on the principles of the Nuss procedure, has almost no possibility of damaging the thoracic organs and large blood vessels because the fixation frame is under the skin and the fixator is fixed to the rib cage. Freeing the periosteum of the ribs first and threading the wire under the periosteum also effectively avoids the possibility of damaging the intercostal vessels. The recent postoperative results are excellent, and one scholar, Abramson, reported an excellent rate of 90% after removal of the fixation frame, which proves that this procedure is feasible. In addition, more importantly, the inferior compression of the thoracic ribs extends the inferior rib portion to both sides, increasing the volume of the thoracic cavity. It also has the advantages of no large median incision, no freeing of bilateral muscles, and no amputation of the sternum and rib cartilage. Therefore, for the treatment of pediatric pectus excavatum, those aged 3 to 10 years can be treated with braces, and those aged 10 years or older can be treated surgically. adolescents aged 10 to 16 years have good elasticity of the chest and ribs, which require less pressure, easy surgical operation, tolerance to surgery, postoperative recovery and better results than late adolescents and adults. In addition, minimally invasive sternal subsidence surgery is simple and less traumatic, so those whose brace treatment is ineffective should consider surgical correction.
