The resting pressure and the pressure changes of the pharyngoesophageal segment during swallowing were recorded in 15 normal subjects.<BR>A specially designed intracorporeal type of measuring device which had three strain gauge type microtransducers was used for the pressure measurements. The three recording orifices were separated by arcs of 120° and by 5-cm intervals in the vertical direction.<BR>C. S. Winans showed in 1972 that the resting pressure within the pharyngoesophageal high pressure zone was dependent upon orifice orientation. According to the present results, the deglutition pressure changes within the high pressure zone was also closely related to orifice direction.<BR>We obtained some useful informations through the analysis of the wave form of pressure changes.
