Flexible endoscopic evaluation of swallowing with sensory testing

Purpose Of Review:
Flexible endoscopic examination of swallowing with and without sensory testing is rapidly becoming a significant tool in the otolaryngologist's armamentarium for diagnosing dysphagia. Patients with swallowing disorders often present to the otolaryngologist, and an understanding of the utility of these techniques is critical.
Recent Findings:
Recent studies have confirmed that flexible endoscopic examination of swallowing with and without sensory testing is an exceptionally safe procedure with excellent portability. Flexible endoscopic examination of swallowing is accurate in diagnosing aspiration when compared with videofluoroscopy. Laryngopharyngeal sensory deficits as assessed by flexible endoscopic evaluation of swallowing with sensory testing are associated with cough, reflux disease, penetration, and aspiration. Both techniques have emerged as complementary to videofluoroscopic studies, rather than as replacements for the modified barium swallow.
Summary:
Flexible endoscopic evaluation of swallowing with and without sensory testing is a safe technique that should be considered in the workup of patients with dysphagia presenting to the otolaryngologist.
