Pectus Excavatum: Causes

Maybe you’ve heard the term ‘bird breast’ or Pectus Carinatum ,  which describes people with advanced breastbone abnormalities. However, have you ever heard the opposite, namely ‘sunken chest’ or Pectus Excavatum?

Want to know more about Pectus Excavatum? Check out this explanation to find information about the understanding, causes, symptoms, diagnosis, complications, and treatment of Pectus Excavatum!

What is Pectus Excavatum?

Pectus Excavatum is a condition of the abnormality of the breastbone and ribs that grows and goes inward. Normally, the breastbone and ribs grow outward (but not excessively as in the case of ‘bird breasts’).

Pectus Excavatum sufferers usually have a sunken breast bone that looks concave like a closed funnel. This is why Pectus Excavatum is also known as the ‘concave chest’.

These bone disorders include congenital abnormalities that are genetically affected, so they can often be detected early in the birth. Pectus Excavatum will be more visible when a person is 2 years old.

However, the incidence of Pectus Excavatum can also be seen in the early teens. It has been reported that Pectus Excavatum often occurs in men compared to women. Pectus Excavatum is rare, but this disorder can be dangerous.

The severity of Pectus Excavatum can be mild, moderate and severe. Pectus Excavatum with mild conditions only reduces the beauty of appearance, but severe Pectus Excavatum can suppress the heart and lungs.

This can lead to several complications related to functions that include both organs. However, there is no need to worry because Pectus Excavatum can be overcome, especially if done long before entering adolescence.

Causes of Pectus Excavatum

The cause of Pectus Excavatum is still unknown. However, it is strongly suspected that Pectus Excavatum occurs due to a genetic abnormality on the chromosome associated with the development of the ribs and sternum.

The disorder causes disability in the cartilage tissue that supports certain ribs. The ribs are ribs that point to the sternum. Disability in the ribs causes the cartilage in that part to push the sternum into it.

Following are some of the risk factors for the occurrence of Pectus Excavatum:

  • Gender – boys are more likely to experience Pectus Excavatum than girls
  • Family history – the presence of a family history of Pectus Excavatum increases the risk factor for the offspring
  • Suffering from Certain Syndrome – Some syndromes such as Marfan’s Syndrome, Ehlers-Danlos Syndrome, Noonan Syndrome, and Turner Syndrome increase the chances of Pectus Excavatum occurring
  •  scoliosis –  children who experience Pectus Excavatum usually also experience scoliosis, which is where the spine curves
  • Osteogenesis imperfecta
