What Is Pectus Carinatum?

Pectus Carinatum is a common chest wall deformity characterized by the forward protrusion of the sternum and adjacent costal cartilages.

Because the chest appears to project outward, it is commonly referred to as Pigeon Chest.

The condition is often subtle during early childhood but may become more noticeable during periods of rapid growth, particularly adolescence.

Is Pectus Carinatum a Common Chest Wall Deformity?

Yes.

Pectus Carinatum is one of the most common congenital chest wall deformities. Although it occurs less frequently than Pectus Excavatum, it can affect children, adolescents, and adults.

Many cases become apparent during puberty when the chest wall grows rapidly.

What Are the Physical Characteristics of Pectus Carinatum?

Common features include:

• Forward protrusion of the sternum

• Prominent chest appearance

• Chest wall asymmetry

• Rib flaring

• Postural abnormalities

• Rounded shoulders

The protrusion may occur centrally or predominantly on one side of the chest.

What Types of Pectus Carinatum Exist?

Symmetric Pectus Carinatum

The sternum protrudes evenly along the center of the chest.

This is the most common presentation.

Asymmetric Pectus Carinatum

The protrusion is more pronounced on one side of the chest.

Chest wall asymmetry may also be present.

Mixed Chest Wall Deformities

Some patients may present with a combination of:

• Chest protrusion

• Localized depression

• Rib abnormalities

These cases often require detailed chest wall evaluation.

Does Pectus Carinatum Affect Health?

Many individuals are primarily concerned about appearance.

However, some patients may experience:

• Reduced exercise tolerance

• Breathing discomfort

• Chest tightness

• Postural issues

Psychological and social concerns are also common reasons for seeking treatment.

At What Age Does Pectus Carinatum Appear?

Childhood

Mild chest protrusion may first become noticeable.

Adolescence

Rapid growth often makes the deformity more apparent.

Adulthood

Without treatment, the chest wall shape generally remains stable.

 What Is the Difference Between Pectus Carinatum and Pectus Excavatum?

Both conditions are chest wall deformities but have opposite appearances.

Pectus Carinatum

The sternum protrudes outward.

Pectus Excavatum

The sternum is sunken inward.

The evaluation and treatment approaches differ between the two conditions.

Does Pectus Carinatum Require Treatment?

Treatment considerations depend on:

• Severity of the protrusion

• Patient age

• Chest wall flexibility

• Psychological impact

• Functional concerns

Some patients only require observation, while others may benefit from brace therapy.

What Treatment Options Are Available?

Observation

Suitable for mild and stable cases.

Brace Therapy

A non-surgical approach that applies controlled external pressure to gradually improve chest wall shape.

Surgery

Typically reserved for severe cases or specific anatomical situations.
