Ultrasonography is used to evaluate soft-tissue dynamics during the oral and pharyngeal phases of swallowing, looking at tongue function and laryngeal/hyoid elevation. Ultrasonography is useful in diagnosing childhood tongue incoordination and could be combined with fiberoptic endoscopic examination of swallowing (FEES) to diagnose extramural and submucosal lesions that FEES alone may not detect.
