Fiberoptic Endoscopic Evaluation of Swallowing

At a Glance

We are excited to announce that our outpatient practice offers fiberoptic endoscopic evaluation of swallowing (FEES).  FEES is a sensitive, accurate, portable, and safe diagnostic tool that yields clinically useful information relative to swallowing physiology and swallowing safety.  The benefits compared to videofluoroscopic swallow study (VFSS), which uses x-ray, are that it is well tolerated, allows in-office examination, avoids radiation exposure, can be repeated safely, accommodates more people (e.g., obesity, wheelchair bound), has less wait time, and is less expensive.  FEES demonstrates a sensitivity equal to or greater than VFSS in determining whether a patient is exhibiting penetration, aspiration, delay in swallowing initiation and pharyngeal residue. There will no longer be a wait-time to initiate therapy, as the report is completed in-house and our SLP is present.  

EST is the only outpatient practice offering FEES in Eugene.

Your Appointment

Your FEES appointment will take 20-30 minutes in total. The SLP will insert a small fiberoptic camera into a nasal passageway, then into the back of your throat, where it is positioned above the vocal cords.​ The SLPs will be able to see your anatomy, determine if there is anything out of ordinary, and will proceed to trialing different foods, liquids, and postures or strategies in order to see how your larynx functions. FEES is also an accurate way to diagnose aspiration.

We see clients first for an intake assessment and then schedule FEES if it is indicated. FEES is possible with a doctor's order. Please contact us to get started or have your doctor send us a referral.
