PMID 38332698WHAT IT FOUND
Dynamic ultrasound of the suprahyoid muscles distinguished patients with oropharyngeal dysphagia from healthy controls.
Combining muscle displacement and total duration achieved 93.3% sensitivity and a 95.6% negative predictive value, suggesting potential as a bedside screening tool.
Key findings
01Patients with severe dysphagia showed significantly smaller suprahyoid muscle displacement and difference compared to those with mild dysphagia and healthy controls.
02Combining suprahyoid muscle difference and total duration parameters yielded a sensitivity of 93.3% and a negative predictive value of 95.6% for identifying dysphagia.
03Ultrasound parameters correlated with videofluoroscopic swallowing study measures, specifically showing negative correlations between muscle displacement/difference and penetration-aspiration scale scores.

What it does not show
VFSS was not available for all patients, limiting the correlation analysis to 54 of the 89 patients. The examination could not be performed in patients who could not maintain an upright head position, excluding those with severe postural instability. Ultrasound parameters focus only on the suprahyoid muscle movement in the oropharyngeal phase and do not represent the entire swallowing process. The study excluded patients who failed the dry swallow test or had decreased mental status, which may limit generalizability to more cognitively impaired populations.

The easy way to misread this
Do not assume this ultrasound method replaces VFSS or FEES for detailed swallowing assessment. It focuses only on suprahyoid muscle movement and cannot evaluate the entire swallowing process or identify the specific mechanism of aspiration, serving best as a screening tool rather than a diagnostic gold standard.
