Videofluoroscopy is a standard procedure to evaluate swallowing dynamics and swallowing disorders. It has been described as a useful method to assess the degree and potential cause of aspiration and/or penetration, to identify possible obstruction or the lack of bolus propulsion involved in dysphagia, and to guide treatment planning in swallowing rehabilitation. The aim of the present chapter is to describe the technical aspects of videofluoroscopy, its principal indications, the key anatomical landmarks used for analysis, and the swallowing study in normal and pathological conditions. So far, videofluoroscopic swallowing studies mostly rely on subjective analysis of the effectiveness of swallowing mechanisms, reviewed in this chapter. However, studies on quantitative analysis of videofluoroscopy currently remain scarce in the literature.
