The exploration of TTAG method in determinating the states of eustachian tube function 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-tymanoaerodynamicgraphy (TTAG) determinating the Eustachian tube function of health adult group.@*METHOD@#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.@*RESULT@#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).@*CONCLUSION@#TTAG method has the clinical value in determinating the states of Eustachian tube function of health group.
