SURE Trial: Swallowing Ultrasound Reliability Evaluation Trial

Use high-frequency ultrasonography to assess the swallowing function in patients with dysphagia. The ultrasound examination focuses on visualization of the pharyngeal region to measure vocal cord movement, swallowing reflex, pharyngeal contraction, and the presence and location of pharyngeal residue.

FEES involves the use of a flexible endoscope inserted through the nasal passage to observe the pharyngeal phase of swallowing directly. This procedure allows for the real-time assessment of key aspects of swallowing, including vocal cord function, swallowing reflex, pharyngeal contraction, and the detection of aspiration or penetration.
