The videoendoscopic swallowing study: an alternative and partner to the videofluoroscopic swallowing study

A new, physical examination-based videoendoscopic method of evaluation can enhance considerably the understanding and efficiency of clinicians working with patients with swallowing difficulties. Using the fiberoptic nasolaryngoscope, evaluation of structure and function of palate, pharynx, and larynx, along with sensation of the laryngopharynx, is carried out. Next, patients' swallowing capabilities are assessed as they ingest various food consistencies. This method, formerly called videoendoscopic evaluation of dysphagia (VEED), but perhaps more appropriately termed videoendoscopic swallowing study (VESS) has particular value for patients who cannot undergo the videofluoroscopic swallowing study (VFSS)--for example, because they are bedfast--or those whose swallowing function is changing so rapidly (after a stroke or surgery) as to call for frequent reassessments. This technique is often useful during the initial consultation with new patients complaining of dysphagia, as a "stand alone" method of diagnosis and management. Less frequently, VESS findings, along with patient history, will indicate when VFSS should also be obtained. VESS will orient the examiner to the nature and severity of the problem even in this latter circumstance. In follow-up circumstances, VESS is generally more useful than the VFSS. Case presentations are utilized to illustrate the usefulness of VESS as compared to VFSS.
