Bilateral expansion K. the item is noted at diffusion emphysema of lungs, acute swelling of lungs during an attack of bronchial asthma. Unilateral expansion K. the item can be at local emphysema of an upper lung lobe, at pheumothorax. Noticeable difference in width right and left To. by the item it is sometimes connected with asymmetric development of a shoulder girdle.

Definition To. the item was of great importance at diagnosis of a pulmonary tuberculosis during a dorentgenovsky era. In sovr. the wedge, practice this research plays a supporting role, however did not lose the value. See also Lungs , Tuberculosis of a respiratory organs .
