Research published in Dysphagia highlights that while FEES is excellent for seeing anatomical detail, VFSS remains the gold standard for seeing "silent aspiration"—where a patient inhales food without coughing or showing external distress. Life After the Recording
A standard "vfss.mp4" captures three distinct phases of swallowing that the naked eye can never see: vfss.mp4
: Uses a tiny camera passed through the nose to get a bird's-eye view of the larynx and pharynx. Research published in Dysphagia highlights that while FEES
: This is the "danger zone." The recording shows the epiglottis closing off the airway and the muscles of the throat pushing food down. vfss.mp4
: The final leg of the journey, where food enters the esophagus toward the stomach.
