Abstract

Priary cricopharyngeal dysfunction is a rare motility disease of the esophagus having a prominent cricopharyngeal bar on barium study in patient with oropharyngeal dysphagia. Abnormal findings of esophageal manometry such as hypertensive upper esophageal sphincter, or failure of relaxation are detectable in only minority of patients suggestive of cricopharyngeal dysfunction. We used radionuclide oropharyngeal transit study which has been proposed as a diagnostic tool for esophageal motility disorder recently. Drug therapy or cricopharyngeal myotomy has been used to treat primary cricopharyngeal dysfunction, We report a case of a 61-year-old woman who presented with oropharyngeal dysphagia and prominent cricopharyngeal bar on barium study. Manometric finding shows a markedly increased pressure of upper esophageal sphinter in the anterior and posterior direction. Radionuclide oropharyngeal transit study shows delayed transit of radioisotope in the oropharynx(Korean J Gastroenterol 1996; 28:602-604.
