Chest wall deformities, or abnormal development and appearance of the chest, can vary from mild to severe. These deformities are considered to be congenital and may be apparent at birth or later in childhood. Regardless, the severity of the malformation usually progresses rapidly during puberty. A variety of anomalies are described however the most common are pectus excavatum (sunken chest or funnel chest) or pectus carinatum (pigeon chest). Less common types of chest wall abnormalities include pectus arcuatum, Jeune syndrome, and defects of the ribs and sternum.

Treatment options include performing NUSS procedure which is a scarless surgery to correct Pectus Excavatum.
