title: Gastroesophageal reflux and pharyngeal function.
abstract: Pharyngeal function and gastroesophageal reflux were compared in 84 dysphagic patients examined clinically and radiologically. Cricopharyngeal muscle incoordination, assessed cineradiographically, was revealed in 5 of 41 patients (12%) without and 17 of 43 patients (40%) with gastroesophageal reflux assessed clinically (p less than 0.05). Thus, there was a positive correlation between dysfunction of the cricopharyngeal muscle and gastroesophageal reflux. There was no correlation with other types of pharyngeal dysfunction. Our results support the assumption of a positive relationship between gastroesophageal reflux and pharyngeal function in terms of cricopharyngeal dysfunction. The pathogenesis of this relation was, however, not revealed.
