Purpose:
To determine the prevalence and severity of functional abnormalities of the pharynx relative to patient age and symptoms.
Materials And Methods:
Radiographic evaluation of the pharynx was performed in 110 consecutive outpatients aged 19-84 years old who had no previous surgery of the larynx, pharynx, or esophagus. Each patient completed a symptom data sheet, and we reviewed medical records to determine the main indication for each examination. Videofluoroscopy and static filming in frontal and lateral positions were done with 20-ml barium boluses. We then evaluated functional abnormalities and classified abnormal findings by type and severity.
Results:
We categorized patients by age into three groups: less than 40 years old (n=31), between 40 and 60 years old (n =42), and greater than 60 years old (n=37). We found a significant increase in the prevalence (23%, 36%, 57%, respectively) and severity of functional abnormalities of the pharynx in older patients (p < .05). Laryngeal penetration, aspiration, pharyngeal stasis, and cricopharyngeal bar were the main abnormalities found in the two older groups. However, we found no correlation between functional abnormalities of the pharynx and symptoms and indications (p > .05).
Conclusion:
Functional abnormalities of the pharynx increased in prevalence and severity with age. Often these findings were not related to specific pharyngeal symptoms and must be interpreted cautiously in older patients.
