Abstract
Sine the pharynx and the esophagus are a functional unit, functional radiodiagnosis has to be directed at pharyngo-esophageal interaction. Among our collective of 73 patients suffering from achalasia or diffuse esophageal spasm, we were able to recognize a substantially increased incidence of morphological or functional pharyngeal disorders by means of cineradiography. The functional alterations in particular were often not revealed by conventional fluoroscopy. High-speed cineradiography, with its high temporal and spatial resolution, turned out to be a valuable tool in analysis of the origin of pharyngeal dysphagia. Manometry correlated very well with the radiologic findings in tubular esophagus, but proved unreliable in the detection of alterations of the upper esophageal sphincter region, because of problems inherent in the method. Furthermore, membranous stenosis (webs), lateral or dorsal diverticula, and asymmetry of the pharynx were observed strikingly often.
