Coordinate Mapping of Hyolaryngeal Mechanics in Swallowing
Published on: May 6, 2014
Abstract:
Simultaneous disorders of the pharynx and esophagus are so frequent that the complete swallowing chain should be examined in all patients with dysphagia. Data are presented to support the concept that such simultaneous disorders represent related phenomena; the mechanism involves changes in cricopharyngeal function seen radiographically as cricopharyngeal prominence. If neurologic disease has been excluded, cricopharyngeal prominence may be the clue to esophageal disease. When cricopharyngeal prominence is found during dynamic imaging of the pharynx, intensive examination of the esophagus and a search for signs of compensation or decompensation in the pharynx should be undertaken.
