Five-step dynamic ultrasonographic assessment of swallowing for dysphagia

Abstract

This paper presents a five-step dynamic ultrasonography (US) technique aimed at diagnosing oropharyngeal dysphagia, which encompasses the analysis of tongue-palate contact, hyoid movement, upper esophageal sphincter opening, vocal fold closure and post-swallow residue. This protocol is implemented in a sequential manner, intending to methodically evaluate the essential phases of swallowing function. By mirroring the natural process of swallowing, this sequential method may provide a full understanding of possible dysfunctions at each stage. Considering the advantages of US in dysphagia diagnosis, we believe that this method will provide clinicians with a perspective for bedside dysphagia evaluation.
