Auditory tubal function was evaluated in two age groups: 20-24 years of age and 50-54 years of age.Active opening function was determined by the sonometric auditory tubal function test, which measures the duration of patency of the auditory tube during swallowing. Passive opening function was determined by sonotubometry and the Valsalva maneuver, which measures the intranasal pressure when tubal opening is produced by the Valsalva maneuver.Significant differences were observed between the two groups.1)Valsalva maneuver opened the auditory tube at an intranasal pressure of 534±173mmH2O in the older group and at 418±242mmH2O in the younger group.2)In the older group, 28% of the tubes were not opened by pressures up to 1000mmH2O, whereas in the younger group, only 16% were not opened.These characteristics of the auditory tubes in the older age groups may be among the causes of adult type serous otitis media, which occurs often in older adults.
