Funnel chest; Cobbler's chest; Sunken chest
Pectus excavatum is a medical term that describes an abnormal formation of the rib cage that gives the chest a caved-in or sunken appearance.
Pectus excavatum occurs in a baby who is developing in the womb. It can also develop in a baby after birth. The condition can be mild or severe.
Pectus excavatum is due to too much growth of the connective tissue that joins the ribs to the breastbone (sternum). This causes the sternum to grow inward. As a result, there is a depression in the chest over the sternum, which may appear quite deep.
If the condition is severe, the heart and lungs can be affected. Also, the way the chest looks may cause emotional stress for the child.
The exact cause is unknown. Pectus excavatum occurs by itself. Or there may be a family history of the condition. Other medical problems linked with this condition include:

Tests may also be done to find out how severely the lungs and heart are affected.
This condition can be surgically repaired. Surgery is generally advised if there are other health problems, such as trouble breathing. Surgery may also be done to improve the appearance of the chest. Talk to your provider about treatment options.
