To explore the feasibility and validity of tubo-tymanoaerodynamicgraphy (TTAG) determinating the Eustachian tube function of health adult group.
The ventilation function of Eustachian tube was measured by the TTAG method in health adult group (132 ears), the results and the graphs were also analyzed.
The positive rate in health adult group using Valsalva method was 93.93% (124/132). The positive ears were divided into type I and type II, the mean value of nasopharynx press of type I and II has no significant differences (P>0.05), but the mean value of external auditory canal press had significant differences (P<0.01).
TTAG method has the clinical value in determinating the states of Eustachian tube function of health group.
探讨咽鼓管-鼓膜空气动力学描记法（TTAG）测定健康成人组咽鼓管功能的可行性和有效性。
采用TTAG法对健康成人组（132耳）进行咽鼓管通气功能检测，并对结果及图形进行分析。
健康成人组采用瓦尔萨尔瓦法的阳性率为93.93%（124/132）。阳性耳分为Ⅰ型和Ⅱ型，Ⅰ型和Ⅱ型的鼻咽部压力均值无显著差异（P>0.05），但外耳道压力均值有显著差异（P<0.01）。
TTAG法在测定健康组咽鼓管功能状态方面具有临床价值。
