What Is Pectus Excavatum?
Pectus deformities occur in 1-8: 1000 population and are more frequent in boys than girls. In pectus excavatum (funnel chest) the sternum (breastbone) is depressed in a concave shape and in pectus carinatum (pigeon chest) the sternum is protruded in a convex shape. There may be asymmetry of the chest and the sternum may be rotated. The deformity varies in severity, ranging from a mild indentation/protrusion to severe, for example a patient with a severe pectus excavatum may have only a few centimetres between his/her sternum and vertebral column. Most patients have a slim chest, a slouching posture and younger children commonly have potbellies.
