Oropharyngeal dysphagia

Abstract

The manometric and cineradiographic features of 14 patients with oropharyngeal dysphagia are described. Failure of the upper-esophageal sphincter (UES) to relax completely and incoordination of UES relaxation with pharyngeal contraction were noted as was poor initiation of swallows and disorganization of pharyngeal contraction. The relative merits of cine esophagography and esophageal manometry in evaluating oropharyngeal dysphagia are assessed, and a functional classification for this disorder is proposed. Clinical improvement in 4 of 5 patients who underwent UES myotomy for severe intractable dysphagia did not always correlate with improvement in manometric and cine studies.
