Abstract: | Pharyngeal manometry complements the modified barium swallow with videofluoroscopy (VFS) in diagnosing pressure-related causes
of dysphagia. When manometric analysis is not feasible, it would be ideal if pressure information about the swallow could
be inferred accurately from the VFS evaluation. Swallowing function was examined using VFS and concurrent manometry in 18
subjects (11 head and neck patients treated with various modalities and 7 healthy adults). Nonparametric univariate and multivariate
analyses revealed significant relationships between manometric and fluoroscopic variables. Increases in pressure wave amplitude
were significantly correlated with increased duration of tongue base to pharyngeal wall contact, reduced bolus transit times,
and oropharyngeal residue. Pharyngeal residue was the most important VFS variable in reflecting pharyngeal pressure measurements.
Certain VFS measures were significantly correlated with measures of pressure assessed with manometry. Further research is
needed before observations and measures from VFS alone may be deemed sufficient for determining pressure-generation difficulties
during the swallow in patients who are unable or unwilling to submit to manometric testing.
