Over half of patients with dysphagia experienced aspiration, often due to reduced laryngeal elevation. This highlights the critical need for modified barium swallow studies in diagnosing swallowing difficulties.

Area of Science:

  • Otolaryngology
  • Radiology
  • Speech-Language Pathology

Background:

  • Dysphagia, or difficulty swallowing, affects a significant patient population.
  • Identifying aspiration is crucial for preventing complications like pneumonia.
  • Modified barium swallow (MBS) is a common diagnostic tool for dysphagia.

Purpose of the Study:

  • To determine the prevalence of aspiration in dysphagic patients undergoing MBS.
  • To identify the underlying causes of aspiration.
  • To assess the association between aspiration history and MBS findings.

Main Methods:

  • A prospective study involving 166 patients referred for MBS over one month.
  • Data collected from five participating institutions.
  • Analysis of aspiration presence, causes, and correlation with patient history.

Main Results:

  • Aspiration was detected in 51.2% of patients.
  • Common causes included decreased laryngeal elevation and delayed pharyngeal response.
  • History of aspiration pneumonia was linked to positive MBS findings.

Conclusions:

  • Aspiration is highly prevalent in dysphagic patients.
  • Reduced laryngeal elevation and delayed pharyngeal response are key causes.
  • The low prevalence of protective cough underscores the necessity of MBS for accurate diagnosis.
