SARANGO, Brayan et al. Videodeglution: an up-to-date study that never gets old. Technique and application in daily practice. Rev. argent. radiol. [online]. 2024, vol.88, n.2, pp.58-65. ISSN 1852-9992.  http://dx.doi.org/10.24875/rar.23000077.

Video swallowing is a physiological and real-time study that, at the moment, cannot be replaced by another modality. It offers relevant information about the patient’s stomatognathic system, as well as the oropharyngeal and esophageal structure and function. This study has different phases (oral, pharyngeal and esophageal) where various structures are analyzed, as well as their functionality through induced objects of different consistencies (semi-solid, liquid and solid). The pathologies that can be found are multiple, some of the most frequent being dysfunction of the cricopharyngeal muscle, penetration/aspiration into the airway, diverticula and achalasia. Its execution with a correct technique is fundamental, knowing previously the symptomatology, reason for which it was indicated, the anatomy of the structures/cavities and the physiology of swallowing. Therefore, an adequate technique in the execution of video swallowing and preliminary knowledge of anatomy and physiology, as well as the most frequent findings and pathologies, are fundamental for a correct evaluation of the patient and interpretation of the images.

Keywords : Fluoroscopy swallowing; Cricopharyngeal muscle; Zenker diverticulum.
