How FEES is Performed 

The Fiberoptic Endoscopic Evaluation of Swallowing (FEES) is a procedure designed to assess swallowing function through the visualization and imaging of the pharyngeal and laryngeal structures. The portable study uses a flexible fiber optic laryngoscope which is passed transnasally. The scope hangs above the epiglottis and does not pass between the vocal folds. During a FEES patients are positioned in a functional feeding position and are offered a variety of food consistencies while the swallow is viewed on a monitor.   ​​
