Tracheobronchial stenosis: causes and advances in management

Abstract

Tracheobronchial stenosis, narrowing of the airways by neoplastic or nonneoplastic processes, may be focal, as occurs with postintubation tracheal stenosis or a focal narrowing from a tumor, or more diffuse, such as those caused by inflammatory diseases. Symptoms develop when the narrowing impedes flow and increases resistance within the airways. Computed tomography defines the extent and severity of disease; endoscopy facilitates understanding of the cause so that an algorithm for treatment can be devised. Bronchoscopic interventions include balloons, ablative treatment, and stenting to provide symptomatic relief. Surgical resection may be curative and a multidisciplinary approach to tracheobronchial stenosis is required.
