[The exploration of TTAG method in determinating the states of eustachian tube function of healthy group].
OBJECTIVE
To explore the feasibility and validity of tubo-tymanoaerodynamicgraphy (TTAG) determinating the Eustachian tube function of health adult group.


METHODS
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.


RESULTS
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).


CONCLUSIONS
TTAG method has the clinical value in determinating the states of Eustachian tube function of health group.
