Benign nontuberculous bronchial stenosis is a rather common complication of infections of the respiratory tract but it is rarely recognized. It is important that more study be given to this type of lesion so that diagnostic accuracy may be increased and proper treatment instituted.
Knowledge of obstructing bronchial lesions has developed but recently. During the eighteenth century, not much attention was given to the clinical study of bronchial obstruction other than that due to foreign bodies.1 Pulmonary emphysema as a result of valvular bronchial obstruction was observed by Laennec,2 who believed it was due to the imprisonment of inspired air behind an obstruction. He assumed a relative weakness in the muscles of expiration as the explanation of this phenomenon. Ingals,2 in 1905, and Gottstein,2 in 1907, called attention to the fact that during inspiration the bronchial lumen is increased in size and that during expiration it is narrowed. The
