Ultrasonographic examination has long been used to assess the swallowing function. It has the advantages of no ionizing radiation on examination and the possibility of using the real food instead of the barium meal in testing. Thus, the subjects can be examined repeatedly and in a more physiological status of swallowing. However, the ultrasonographic examination is only used in assessing the oral phase of swallowing. It can accurately visualize the tongue movement, measure the oral transit time of bolus, and sometimes the hypoid bone motion, but has not been applied on the evaluation of pharyngeal phase of swallowing. Physically, laryngeal elevation is an essential component of the swallowing movement on pharyngeal phase. It ensures the occlusion of airway and opening of criopharymgeus muscle, and thus prevents the aspiration. To evaluate the laryngeal elevation is crucial point in managing the dysphagic patients.
