Description
Summary:This study aimed to investigate the effects of a tongue-holding maneuver (THM) during swallowing using a novel high-resolution manometry (HRM) system. Case series with planned data collection. Thirty-three asymptomatic Japanese adults were studied. A solid-state HRM assembly with 36 circumferential sensors spaced 1-cm apart was positioned to record pressures from the velopharynx to the upper esophagus at rest and during swallowing. The maximum values of the dry swallowing pressures at the velopharynx, mesohypopharynx, upper esophageal sphincter (UES), and distance from the nostril to each point of maximum values with and without the THM were measured. The distance from the nostril to the UES was statistically shorter when swallowing with the THM than without the THM (paired t test, P = 0.009). The maximum pressure at UES was greater when swallowing with the THM than without the THM, although there was no statistically significant difference (paired t test, P = 0.051). There was no difference in the pressures and the distance between swallowing with or without the THM at any other site. These findings suggest that the THM may not have a potential to facilitate compensatory swallowing power when swallowing.
