What is FEES?

  • Susan Langmore, Ph.D., and her research team coined the term FEES in 1986 and published the first data demonstrating the effectiveness of the procedure in 1988.
  •  A thin, flexible instrument is inserted through your nose to help your Speech-Language Pathologist view parts of your throat as you swallow.

  • The FEES test has two basic parts. During the first, your SLP will view and record the structure of the pharynx and larynx. Then your SLP will introduce food to assess your swallowing. Food coloring will be used to dye food and liquids so they may be viewed better on the screen. You may be asked to try different positions or types of foods during the evaluation.


Is Imaging Necessary?

A Speech-Language Pathologist (SLP) cannot effectively treat what they cannot see.

Per the American Speech-Language-Hearing Association, an instrumental swallow study (imaging) is necessary to complete any of the following:

  • Assess the physiology of the structures involved in swallowing to determine a diagnosis of dysphagia

  • Determine presence, cause, and severity of dysphagia 

  • Visualize the presence, location, amount, and response to secretions in the hypopharynx and larynx

  • Determine the cause(s) for laryngeal penetration and/or aspiration

  • Determine with specificity the relative safety and efficiency of various bolus consistencies and volumes.

  • Can be performed in nearly any environment

  • No need to coordinate with radiology

  • No radiation exposure

  • Easily performed on patients who are obese or medically fragile, unlike MBSS

  • Can be performed on patients with mechanical ventilation, even in their room

  • No need for barium. Patients eat regular food.

  • One fixed cost. No hidden fees/charges.

It is the official position of the American Speech-Language-Hearing Association (ASHA) that endoscopy is an imaging procedure included within the scope of practice for speech-language pathologists and described in previously established ASHA documents.
