Although initial manometric studies of Eustachian tube ventilatory function in both normal and abnormal ears suggested that this technique provided an accurate physiologic assessment of ventilatory function, recent studies have questioned the physiologic nature of these tests. In an effort to clarify this controversy, the tubal ventilatory capacity of 51 ears in which Eustachian tube function was clinically normal was assessed manometrically. Similar measurements were made in 18 ears in which Eustachian tube function was clinically normal except for a complaint of aural fullness. This group showed poorer ventilatory function than normal ears, but the most striking result was the inability of over 50% of the normal group to equilibrate negative pressure to a level within the normal range of 0 to -50 mm H2O. It is postulated that Eustachian tube ventilatory function exhibits a range of individual variability such as is characteristic of other biologic systems.
尽管最初对正常耳和异常耳咽鼓管通气功能的测压研究表明，该技术能对通气功能进行准确的生理评估，但最近的研究对这些测试的生理特性提出了质疑。为了澄清这一争议，对51只临床咽鼓管功能正常的耳朵进行了测压，评估其咽鼓管通气能力。对18只临床咽鼓管功能正常但有耳闷主诉的耳朵也进行了类似测量。该组的通气功能比正常耳差，但最显著的结果是，超过50%的正常组无法将负压平衡到0至-50毫米水柱的正常范围内。据推测，咽鼓管通气功能存在个体差异范围，这是其他生物系统的特征。
