Can mild pectus carinatum in children be corrected? Pectus carinatum, commonly known as pigeon chest, is the second most common chest deformity encountered, after funnel chest. As the name suggests, pigeon chest refers to a protrusion of the sternum in the center, similar to the chest of a chicken or pigeon, where the sternum protrudes forward. This protrusion, to draw an analogy, is like a tree. This young sapling has already grown crooked. You cannot straighten it by fertilizing or any other means. Correction is only possible through procedures such as orthotic braces or compression, or more directly and effectively through surgical intervention. Surgery is the most straightforward and immediately impactful treatment method.
