Brief summary
This study aims to explore the reliability of using ultrasonography (US) for the assessment of swallowing function in patients with dysphagia. The study will recruit 80 patients and compare the findings with those obtained from fiberoptic endoscopic evaluation of swallowing (FEES), which serves as the gold standard.
Detailed description
This study will evaluate the reliability of using ultrasonography as a non-invasive tool for assessing swallowing function in patients with dysphagia. Participants will undergo US and FEES assessments to examine vocal cord function, swallowing reflex, pharyngeal contraction, aspiration/penetration, and stasis. The reliability, diagnostic accuracy, and inter-/intra-rater reliability will be analyzed to validate US as an effective alternative in clinical dysphagia assessment.
Interventions
DIAGNOSTIC_TESTultrasound evaluation
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.
DIAGNOSTIC_TESTFiberoptic endoscopic evaluation of swallowing (FEES)
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.
