A barrel chest is characterized by an increase in the anteroposterior diameter of the thorax and is a result of overinflation of the lungs. A pigeon chest occurs as a result of displacement of the sternum and includes an increase in the anteroposterior diameter. Kyphoscoliosis is characterized by elevation of the scapula and a corresponding S-shaped spine and limits lung expansion within the thorax.
