Abstract

Aspiration is the entry of materials, such as pharyngeal secretions, food, or stomach contents, into the respiratory system. Dysphagia is the most common risk factor of aspiration, but there are many other risk factors. A single factor or multiple factors may be present to induce the aspiration, and the risk factors of aspiration should be considered multidimensional. The bedside water test is suitable as a screening test for an evaluation of aspiration. Videofluoroscopic swallowing study and flexible endoscopic evaluation of swallowing are the diagnostic tests of aspiration and the tests are required if the screening test shows signs of aspiration or silent aspiration is strongly suspected. The diagnostic test should assess not only the presence of aspiration, but also the pathophysiologic risk factors of aspiration.
