Abstract
PURPOSE: This study used simultaneous videomanometry to measure pressure characteristics in a group of patients with evidence of laryngeal and/or tracheal barium penetration, and to compare the results to those of one group of healthy volunteers and one group of patients with dysphagia but a normal barium swallow. MATERIAL AND METHODS: Videomanometry during barium swallowing was performed in 25 patients who showed penetration of barium into the laryngeal vestibule. Manometric abnormalities were determined by comparing these mean values with those of 25 healthy volunteers, and the frequency of manometric abnormalities was compared to that of 19 patients presenting with oropharyngeal dysphagia with a normal barium swallow. RESULTS: The... (More)

MATERIAL AND METHODS: Videomanometry during barium swallowing was performed in 25 patients who showed penetration of barium into the laryngeal vestibule. Manometric abnormalities were determined by comparing these mean values with those of 25 healthy volunteers, and the frequency of manometric abnormalities was compared to that of 19 patients presenting with oropharyngeal dysphagia with a normal barium swallow. RESULTS: The frequency of abnormalities for four parameters (pharyngo-esophageal segment (PES) resting pressure, PES relaxation duration, pharyngeal peak pressure, pharyngeal contraction duration) differed significantly between the patients with penetration and those with normal barium studies. There was, however, no association between manometric abnormalities and the degree of barium penetration. CONCLUSION: The differences in manometric abnormalities between patients with laryngeal penetration and patients with normal barium swallows may be useful in identifying the mechanisms of laryngeal penetration.
