Abstrakt:	The purpose of this paper is to analyze cervical dysphagia with a two-modality method using simultaneous fluoroscopy and solid-state computerized manometry (manofluorography). Manofluorography provides functional data that are not obtainable using barium swallow or standard manometry. Six examples of pharyngeal dysphagia are presented. They show that pharyngeal bolus transit is due to a pressure gradient. Two major generators of this gradient are tongue-driving pressure and the pharyngeal-esophageal segment negative pressure. Dysphagia is analyzed in terms of alteration of the pharyngeal pressure gradient. [ABSTRACT FROM AUTHOR]
