What is Pectus Carinatum?

Pectus Carinatum is a rare and genetic deformity of the chest wall. It makes the breast-bone (sternum) bulge out and results in the appearance of a pigeon, hence the name pigeon chest. 

What Should You Know About Pectus Carinatum? 

Pectus Carinatum or pigeon chest is a birth defect, but it is not noticeable till the child reaches puberty. It starts during the development of the chest wall. The abnormal outward growth of the cartilage that connects the ribs results in pectus carinatum. Although not very common, affects more boys than girls. 

Pectus carinatum is often asymmetrical, with affecting one side of the chest more than the other. Besides, few children have pectus carinatum on one side of the chest with an indentation known as pectus excavatum on the other side of the chest.

Approximately 15 per cent of children with it develop scoliosis.

The incidence of pectus carinatum is four times higher in boys than in girls. Pectus carinatum affects the appearance of the child, who may feel short of breath during physical activities. Treatment of pigeon chest is possible with surgeries and the use of braces.

What are the Treatment Options for Pectus Carinatum?

Most cases require treatment to correct the deformity and enhance the appearance of the child.

  • Orthotic bracing: Bracing is an ideal treatment for mild-to-moderate cases of pectus carinatum. They place the braces on the chest. These braces exert pressure on the site with deformity and help flatten the chest bone for a normal appearance. 
  • Surgical option: The doctor may suggest surgery if bracing does not help. Surgery is also suitable for individuals with severe symptoms that are affecting overall health and growth. Doctors remove the cartilage and reposition the breast bone during the surgery. 


Pectus carinatum is a genetic disorder that causes deformity of the chest wall. It results in an abnormal appearance and can cause several symptoms. Your child may not require any treatment if the condition is mild and is not affecting the appearance. Doctors may consider the use of bracing or surgery to treat severe cases.
