ABSTRACT
Objective:
To investigate the effect of exogenous surfactant on Eustachian tube opening function.Methods:
This reasarch measures for the Eustachian tube opening pressure by injection of surface active substance into middle ear space, studying the effect of surfactant on Eustachian tube opening function.Results:
It has been showed that the injection of killed streptococcus pneumoneac bacteria by the transtympanic route, successfully developed a secretory otitis media model. Eustachian tube opening pressure in ears with SOM was significantly greater than those without effusion (P<0.01). Irrigation the middle ear space with surfactant resulted in a dramatic decrease in eustachian tube passive opening pressure in both normal and patients (P<0.01).Conclusion:
The results indicate that flushing with exogenous surfactant by the transtympanic rote reduce of eustachian tube surface tension, and it benefits the Eustachian tube opening.
