What is FEES?

Flexible Endoscopic Evaluation of Swallowing (FEES) is an instrumental swallow study that uses a flexible endoscope. During the exam, the scope is passed through the nose and into the back of the throat where a camera is used to visualize the pharynx, larynx, and upper esophageal opening. The patient is given various items to eat and drink, dyed green to evaluate the swallowing function, determine safest diet level, and presence of aspiration. The exam is performed by a qualified and licensed Speech Language-Pathologist (SLP) for patients with dysphagia (swallowing disorder).
