Flexible fiberoptic bronchoscopy can be a useful diagnostic and therapeutic procedure. Bronchoscopy helps evaluate the cause of bronchial obstruction. In addition, bronchoscopy helps clear mucous plugs when they cause bronchial obstruction. Bronchoscopy has limitations. Because only the subsegmental bronchi are visualized, a distal endobronchial lesion is not accessible through bronchoscopy.

In an evaluation of middle lobe syndrome, bronchoscopy may show an endobronchial etiology (mucus plugging/broncholithiasis/tumor), although inflammatory processes and defects in the bronchial anatomy and collateral ventilation have been designated as the nonobstructive causes of the syndrome.
