FEES stands for Fiberoptic Endoscopic Evaluation of Swallowing and is performed by a trained specialists. FEES uses an endoscope (a small flexible tube with a camera and light on the end) to objectively assess a person's ability to swallow. The endoscope is guided through a patient's nasal passage into the throat so the pharynx and upper esophageal opening can be viewed from above.
During the 20-30 minute assessment, the patient will be administered liquids and food mixed with food coloring to view swallow function and anatomy before, during, and after swallowing.
The endoscope is connected to a computer with video monitoring so the therapist and patient can view the results in real-time.
