Abstract EN
The aim of this study was to investigate oropharyngeal pressure flow dynamics during dry swallowing in ten healthy subjects.
Tongue pressure (TP) was measured using a sensor sheet system with five measuring points on the hard palate, and pharyngeal pressure (PP) was measured using a manometric catheter with four measuring points.
The order and correlations of sequential events, such as onset, peak, and offset times of pressure production, at each pressure measuring point were analyzed on the synchronized waveforms.
Onset of TP was earlier than that of PP.
The peak of TP did not show significant differences with the onset of PP, and it was earlier than that of PP.
There was no significant difference between the offset of TP and PP.
The onset of PP was temporally time-locked to the peak of TP, and there was an especially strong correlation between the onset of PP and TP at the posterior-median part on the hard palate.
The offset of PP was temporally time-locked to that of TP.
These results could be interpreted as providing an explanation for the generation of oropharyngeal pressure flow to ensure efficient bolus transport and safe swallowing.
