Pectus Excavatum is the most frequently seen chest wall deformity. Chest wall deformities are classified in five categories consisting of Pectus Excavatum, Pectus Carinatum, Poland Syndrome, Sternal defects, and the uncommon chest wall deformities (1). 85% of the deformities can be detected in the first year of life.
Pectus Excavatum can be called as “sunken or hollowed chest” (Figure 1).
Pectus Excavatum can be seen together with Pectus Excavatum pectus carinatum (PC) in 6.8% of the patients which is called “mixed deformity”.
