Bolus Airway Invasion Observed During Videofluoroscopy in Healthy, Non-dysphagic Community-Dwelling Adults.

Entrance of ingested material into the airway observed during videofluoroscopy is uncommon in healthy adults, which helps support the notion that aging may not directly correlate with increased risk of aspiration. Rather, the increased risk of aspiration observed in the aging population may result from the increased incidence of neurological and other diseases with dysphagia as common sequelae with advancing age. Future investigations should compare age-matched healthy controls with a diseased population (eg, cerebral vascular accident) to further explore the relationship between aspiration risk as a function of age compared to consequence of disease/injury.
