- Oral and pharyngeal function in 131 institutionalized elderly patients with advanced dementia was evaluated by means of videofluoroscopic deglutition examination (VDE). Findings were normal in only nine (7%) patients. Oral-stage dysfunction was observed in 93 (71%) patients, pharyngeal dysfunction in 56 (43%), and pharyngoesophageal-segment abnormalities in 43 (33%). Multiple-stage dysfunction was noted in 55 (42%) patients. Major aspiration of contrast medium was present in 31 patients, and minor aspiration in 66. Evaluation of VDE findings prompted a change in clinical staging (degree of impairment) in 40 patients and substantial alteration in treatment planning in 28. At clinical bedside evaluation, the degree of bolus misdirection was overestimated in 19 patients with minor aspiration and underestimated in seven with major aspiration. Dementia is often associated with oral and pharyngeal impairment, and VDE can be important in diagnosis and treatment.

- Swallowing disorder is an increasing problem in our aging population. A majority of these patients have a functional abnormality of the oral, pharyngeal, and/or esophageal stage of swallowing. However, what constitutes normalcy is not well understood, and baseline swallowing in elderly persons without dysphagia has not been adequately described. We therefore evaluated 56 persons with a mean age of 83 years who had no symptoms of dysphagia or eating difficulty. Videofluoroscopy and radiographs with the subject erect and recumbent were obtained. Normal deglutition, as defined in young persons, was present in only 16%. Oral abnormalities (difficulty ingesting, controlling, and delivering bolus relative to swallowing initiation) were seen in 63%. Pharyngeal dysfunction (bolus retention and lingual propulsion or pharyngeal constrictor paresis) was seen in 25%. Pharyngoesophageal segment abnormalities were observed in 39% (mostly cricopharyngeal muscle dysfunction). Esophageal abnormalities (mostly motor in nature) were observed in 36%. What has been described as swallowing dysfunction in young persons may not be abnormal in very elderly persons. It is difficult to distinguish the effect of normal aging from the effects of specific diseases or gradual degenerative changes.

- 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.
