Pharyngoesophageal interrelationships: observations and working concepts

Area of Science:

• Gastroenterology and Otolaryngology
• Swallowing Disorders
• Deglutition Physiology

Background:

• Simultaneous disorders of the pharynx and esophagus are common in patients experiencing dysphagia.
• The complete swallowing chain, encompassing both pharyngeal and esophageal functions, requires thorough evaluation.
• Understanding the relationship between pharyngeal and esophageal motility is crucial for diagnosing swallowing impairments.

Purpose of the Study:

• To present data supporting the concept that simultaneous pharyngeal and esophageal disorders are related phenomena.
• To highlight the role of cricopharyngeal function changes, specifically cricopharyngeal prominence, in these disorders.
• To establish cricopharyngeal prominence as a potential indicator of esophageal disease in the absence of neurologic conditions.

Main Methods:

• Radiographic assessment of the swallowing mechanism, focusing on dynamic imaging of the pharynx.
• Evaluation of cricopharyngeal function and the identification of cricopharyngeal prominence.
• Correlation of radiographic findings with clinical presentation and exclusion of neurologic etiologies.

Main Results:

• Data suggest that simultaneous pharyngeal and esophageal disorders are linked phenomena.
• Changes in cricopharyngeal function, observed as cricopharyngeal prominence, are implicated in the mechanism.
• Cricopharyngeal prominence, when found during pharyngeal imaging, is a significant radiographic finding.

Conclusions:

• In patients with dysphagia, a comprehensive examination of the entire swallowing chain is essential.
• Cricopharyngeal prominence, identified via dynamic pharyngeal imaging, may serve as a key indicator of esophageal disease.
• When cricopharyngeal prominence is noted, further esophageal investigation and assessment of pharyngeal compensatory mechanisms are warranted.
