FEES can identify a range of swallowing disorders, including:
Pharyngeal dysphagia: Difficulty in the pharyngeal phase of swallowing. Laryngeal penetration: When food or liquid enters the larynx but does not pass below the vocal cords. Aspiration: When food or liquid passes below the vocal cords into the trachea. Residue: Leftover food or liquid in the pharynx after swallowing. Structural abnormalities: Tumors, strictures, or other anomalies affecting swallowing.
