Videofluoroscopy in elderly patients with aspiration: importance of evaluating both oral and pharyngeal stages of deglutition

Oropharyngeal functional impairment increases with age so that radiologists frequently are asked to determine the cause of aspiration in elderly patients. Neuromuscular and cognitive impairment often make it difficult to perform and interpret videofluoroscopic deglutition examinations in these patients. We retrospectively reviewed the barium swallow examinations in 50 elderly patients (mean age, 87 years) who were known to aspirate. We looked for specific patterns of oropharyngeal dysfunction that resulted in bolus misdirection. Analysis revealed that aspiration was due to abnormalities of the oral stage in 23, pharyngeal stage in 10, and both stages in 17. Dysfunction in the oral stage was due to ingestion of large volumes or rapid acquisition rates in nine, failure of containment during processing (bolus manipulation) in 18, and dissociation of lingual delivery and swallowing initiation in the transitional phase in 13. Dysfunction in the pharyngeal stage was due to incomplete transport (bolus retention) in 21 and defective closure of the laryngeal vestibule in 11. No significant relationship between conditions known to cause oropharyngeal dysfunction (dementia, stroke, Parkinson disease, disuse deconditioning) and the specific pattern of dysfunction was identified. These results indicate that an accurate and valid assessment of oropharyngeal dysfunction in elderly patients with aspiration is possible if specific patterns of dysfunction are sought. Our study indicates the importance of evaluating the oral and pharyngeal stages of deglutition in elderly patients who aspirate.
