Decoding videofluoroscopic swallowing studies sip by sip

Part 1 - normal findings

Abstract

Deglutition is a complex neuromuscular mechanism that transforms and transports food to the oesophagus, while preventing aspiration to the airway. Defects in the swallowing mechanism are responsible for oropharyngeal dysphagia, a common symptom with increasing incidence in the elderly and with a negative impact in quality of life.

Videofluoroscopic swallowing studies are dynamic and non-invasive imaging tests that complement the clinical evaluation of dysphagia and remain relevant in current clinical practice. These allow anatomic and functional characterization of the structures involved in swallowing and development of a targeted rehabilitation plan.

This article reviews the deglutition mechanism, presents the imaging protocol used in our institution and summarizes key imaging findings in normal videofluoroscopic swallowing studies.
