The exploration of TTAG method in determinating the states of Eustachian tube functiong of healthy group / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

Objective:To explore the feasibility and validity of tubo-tymanoaerodynamic graphy(TTAG)determinating the Eustachian tube function of health adult group.MthodThe ventilation function of Eustachian tube was measured by the TTAG method in health adlut group(132 ears),the results and the graphs were also analyzed.ReslutThe positive rate in health adult group using Valsalva method was 93.93%(124/132).The positive ears were divided into typeⅠand typeⅡ, the mean value of nasopharynx press of type Ⅰand Ⅱ has no significant differences(P>0.05),but the mean value of external auditory canal press had significant differences(P<0.01).Conclusion:TTAG meathod has the clinical value in determinating the states of Eustachian tube function of health group.
