This video demonstration illustrates myself (James Curtis, PhD, SLP) passing a flexible laryngoscope transnasally on Allie Beam, MS, SLP, with assistance from Jina Nam, MS, SLP. We are completing what is known as a Flexible Endoscopic Evaluation of Swallowing (FEES).

Please note, the protocol used in this video is the same that is outlined in the VASES normative study (reference below) which involves 15 bolus presentations. However, clinically the standardized protocol I use is only 9 boluses, thus typically resulting in a shorter exam. For interested individuals, the protocol I use clinically is: 5 mL, held, cued, single swallow of green opaque water; 5 mL (not held or cued), single swallow of white coating water; 10 mL , single swallow of green opaque water; 20 mL , single swallow of white coating water; Self-selected volume of green opaque water (with sip size recorded using a digital food scale); Self-selected volume of white coating water (with sip size recorded using a digital food scale); 90 mL uninterrupted, sequential swallow of white coating water; 5 mL of blue dyed vanilla pudding (two trials); Self-selected volume of cracker (with sip size recorded using a digital food scale; two trials). All nine of those trials are rated using VASES. Of those nine trials, VASES ratings for all except the 5 mL cued swallow and the 90 mL sequential swallow are used to derive DIGEST-FEES grades.
