Continued Relevance of Videofluoroscopy in the Evaluation of Oropharyngeal Dysphagia

Abstract

In the last decade, fluoroscopy in the radiology department has been largely replaced by more modern imaging techniques; however, the visualization of oropharyngeal swallowing function is still one of the hallmarks of fluoroscopy. This article describes the technique and interpretation of swallowing videofluoroscopy. As the evaluation of swallowing is a dynamic study with important, discrete events occurring rapidly, the fluoroscopic acquisition rate must be continuous or no less than 30 pulses per second. If the acquisition rate is less, important clinical information will be missed. Other swallowing evaluation techniques such as endoscopy, magnetic resonance imaging, and manometry are available. While each offers some advantages, their limitations preclude them from being the best evaluation tool for oropharyngeal swallowing. The videofluoroscopic swallowing study remains a relevant and efficient instrumental evaluation for the management and rehabilitation of oropharyngeal swallowing.
