Videofluoroscopic upper esophageal sphincter function in elderly dysphagic patients.

Area of Science:

• Gerontology
• Gastroenterology
• Speech and Hearing Sciences

Background:

• Dysphagia is a common complaint among the elderly, often impacting quality of life.
• The upper esophageal sphincter (UES) plays a critical role in safe swallowing.
• Abnormalities in UES function can contribute to oropharyngeal dysphagia.

Purpose of the Study:

• To identify and characterize abnormalities in the timing and extent of upper esophageal sphincter (UES) opening.
• To investigate UES function in elderly patients experiencing dysphagia without a clear medical or surgical cause.

Main Methods:

• Retrospective review of dynamic swallowing studies in patients over 65 with dysphagia.
• Comparison of UES opening measures with young and elderly normal control groups.
• Evaluation of the relationship between UES function and other swallowing abnormalities.

Main Results:

• No reduction in the size (extent) of UES opening was observed in the dysphagic elderly group.
• UES opening timing was prolonged in patients with dysphagia.
• Prolonged UES opening correlated with impaired pharyngeal clearing, suggesting reduced pharyngeal muscle constriction.

Conclusions:

• The study found no primary abnormality in the extent or timing of upper esophageal sphincter (UES) opening in elderly patients with dysphagia.
• Dysphagia in this population may be related to other factors, such as reduced pharyngeal constriction, rather than primary UES dysfunction.
