    Summary
    This summary is machine-generated.

    Gastroesophageal reflux is linked to cricopharyngeal muscle dysfunction in patients with swallowing difficulties. This study found a significant correlation, suggesting a relationship between reflux and impaired pharyngeal function.

    Area of Science:

    • Otolaryngology
    • Gastroenterology
    • Deglutition Science

    Background:

    • Dysphagia is a common symptom with various underlying causes.
    • Gastroesophageal reflux disease (GERD) can affect upper aerodigestive tract function.
    • The relationship between GERD and specific pharyngeal motility disorders requires further elucidation.

    Purpose of the Study:

    • To investigate the association between gastroesophageal reflux and pharyngeal function in patients with dysphagia.
    • To specifically assess the prevalence of cricopharyngeal muscle incoordination in relation to GERD.

    Main Methods:

    • Clinical assessment of gastroesophageal reflux.
    • Cineradiographic evaluation of pharyngeal function, including cricopharyngeal muscle coordination.
    • Comparison of cricopharyngeal dysfunction rates between patients with and without GERD.

    Main Results:

    • Cricopharyngeal muscle incoordination was significantly more prevalent in patients with GERD (40%) compared to those without (12%) (p < 0.05).
    • A positive correlation was observed between gastroesophageal reflux and cricopharyngeal muscle dysfunction.
    • No correlation was found between GERD and other types of pharyngeal dysfunction.

    Conclusions:

    • The findings support a positive relationship between gastroesophageal reflux and cricopharyngeal dysfunction in dysphagic patients.
    • GERD may play a role in the pathogenesis of cricopharyngeal incoordination.
    • Further research is needed to understand the underlying mechanisms of this association.
