Abstract

The aim of the study was to determine the manometric patterns in dysphagic patients with radiologic evidence of upper esophageal sphincter (UES) dysfunction. Nineteen patients with radiographic abnormalities of the UES underwent measurement of several parameters of UES tonic pressure and pharyngoesophageal water swallow dynamics. At least two UES tonic pressures were elevated in six subjects, compared with a control group of 67 healthy volunteers. No patients had UES achalasia. The cricopharyngeal impression in the remaining patients may represent muscular hypertrophy or deficiency of UES opening, despite manometric relaxation, but its relationship to the patient's symptoms remains unknown. Cricopharyngeal myotomy appears to be a reasonable treatment for patients with manometric UES hypertonicity.
