What is the PECTUS EXCAVATUM?
The Pectus Excavatum causes sagging or funnel of the sternum, especially in its lower portion. this is why many people know it as a chest or a sunken chest.
It is the most common deformity of the chest wall during childhood and adolescence and is believed to be due to a disorder in the development and growth of the costal cartilages, which will drag the sternum inward; a circumstance that can be accentuated during the growth of the child.
It is a disease that is estimated at 1 in 700-1000 births, especially in males, and that usually becomes more and more visible over the years, with adolescence being a key moment. There are people who from birth already have a certain sinking of the sternum and there are others, who during puberty is when they experience this circumstance.
This sagging of the sternum can put pressure on the internal organs of the rib cage, causing respiratory and cardiac abnormalities. It may lead to poor sports tolerance, premature exhaustion, may be associated with nonspecific specific chest pains and may sometimes be associated with scoliosis or winged floating ribs.
While all of this is unusual, and most cases of children or patients with Pectus Excavatum are mild or moderate cases, which mainly involves a cosmetic and psychological problem, which can also severely affect the development and day to day life. the people.
Are there different types of Pectus Excavatum?
The truth is that yes. It is most common to encounter a funnel in the lower third of the sternum, centered and symmetrical. Some authors call these Type 1s.
But not always a Pectus Excavatum is symmetrical. Shapes can be found in the form of a "long funnel" that affects virtually the entire sternum (Type 2), or asymmetrical shapes (Type 3), perhaps more common than literature suggests.
In any case, in the Pectus Excavatum there is always an abnormal position of the sternum and costal cartilages, especially at the lower level, which will mark a decrease in the anteroposterior diameter of the rib cage with involvement, in cases of pulmonary and / or cardiac function, as I was commenting earlier. Although the psychological and / or aesthetic problems are the most common.
