When discussing treatment methods for children with pectus carinatum, it's important to consider the severity of the condition. Generally, mild to moderate cases do not require special treatment. For children under 18, most can wear a chest orthosis to correct the condition. Many people achieve good results after wearing it. However, some severe cases of pectus carinatum may compress the heart and lungs, causing cardiopulmonary dysfunction, and surgical treatment should be considered. Current surgical methods for pectus carinatum are minimally invasive, and generally, patients recover well postoperatively. Therefore, the treatment method for pectus carinatum should be determined based on the actual situation.
