Literature Comparing Efficacy of Endoscopic and Fluoroscopic Swallow Evaluations: 


  • Bedside clinical swallow exams by SLPs have proven to be under-estimating and over-estimating aspiration; therefore, the use of instrumental swallow evaluations is imperative.


  • Studies show there is a good agreement between MBSS, also known as videofluoroscopic studies, and FEES when examining premature spillage, pharyngeal residue, laryngeal penetration, and tracheal aspiration.


  • FEES has proven to be as sensitive as, or more sensitive than the MBSS relative to standard swallowing parameters.

Literature Supporting Additional Information Obtainable through FEES: 


  • Because the recording of FEES lasts longer than the MBSS, signs of esophageal motility dysfunction as well as aspiration/penetration after the swallow is detected more often than in the MBSS.


  • Through direct visualization of FEES, anatomical variants and tissue/muscle abnormalities are identifiable, allowing for a distinct picture of the true etiology for the dysphagia.

​​

  • FEES has proven to be a good assessment of saliva management, which is a high risk factor for pneumonia.
