Videofluoroscopy is a moving x-ray study of swallowing.With this procedure,the examiner is able to determine the duration and completeness of bolus transit as well as the movement patterns of the mandible,tongue,velum,larynx,and to some extent,the pharyngeal wall and upper esophageal sphincter.Also,the symmetry of transport can be observed.Penetration of the material into the laryngeal vestibule and aspiration of the material into the trachea can be observed in this procedure.Patients are given small boluses of varying viscosities in accordance with their level of tolerance.Bolus preparations range from 3 to 20 ml.
