Chest wall deformities are structural abnormalities of the chest that can affect its shape and function. Common types include pectus excavatum, where the chest appears sunken, and pectus carinatum, characterized by a protruding chest. These conditions can vary in severity and may impact breathing and physical activity. These deformities can be present at birth or develop during childhood and adolescence. While some individuals may not experience significant issues, others might require treatment, which can include physical therapy or surgical options. Early diagnosis and management can help improve quality of life and overall health.
