Congenital pectus excavatum: Early signs in young children

1. What is congenital pectus excavatum?

Congenital pectus excavatum is a chest wall deformity in which the sternum and costal cartilages develop abnormally and become depressed inward, creating a concave appearance in the middle of the chest. This deformity may be present from birth or become more pronounced over time, particularly during periods of rapid growth.

Congenital pectus excavatum accounts for approximately 80–90% of chest wall deformities, making it the most common type of anterior chest wall deformity. It occurs more frequently in boys than in girls.

2. Early signs of congenital pectus excavatum in young children

Parents can detect congenital pectus excavatum early by looking for the following signs:

• A noticeable depression in the middle of the chest, which is easily observed when the child is lying on their back
• The depression becomes more pronounced when the child takes a deep breath, cries, or engages in physical activity
• An asymmetrical chest, with uneven development of the two sides of the chest wall
• In older children, the following may occur:
  • Easy fatigue during physical activity
  • Rapid breathing or shortness of breath
  • Frequent respiratory tract infections
  • Low self-esteem about their appearance

In newborns and infants, pectus excavatum often does not cause obvious cardiopulmonary dysfunction and may therefore be overlooked without careful examination.

3. Is congenital pectus excavatum dangerous?

The impact of congenital pectus excavatum depends on the depth and extent of the chest depression:

• Mild cases: primarily affect appearance, with little impact on respiratory or cardiovascular function
• Moderate to severe cases:
  • Compression of the heart and lungs
  • Reduced lung capacity
  • Limited exercise capacity
  • Long-term psychological effects if not appropriately treated

4. When should children be taken for medical evaluation?

Parents should take their child to a hospital or specialized medical facility when:

• They notice a pronounced chest depression or progressive worsening of the deformity
• The child experiences shortness of breath or fatigue during physical activity
• The child enters the prepubertal or pubertal period, when the deformity tends to progress rapidly

The physician will perform an examination and may order necessary diagnostic tests, such as chest X-rays, chest CT scans, pulmonary function tests, and echocardiography, to assess the severity of the deformity and determine the appropriate management approach.

5. Principles of monitoring and treatment

Depending on the severity of pectus excavatum, children may receive:

• Regular monitoring for mild cases
• Physical therapy and breathing exercises to improve posture and lung function
• Surgical correction of the chest wall (Nuss procedure) for moderate to severe cases, which generally provides good outcomes when performed at the appropriate time

6. Message for parents

Congenital pectus excavatum is not always dangerous. However, early detection, appropriate monitoring, and timely intervention can help children achieve healthy physical and psychological development and improve their long-term quality of life.
