Methods Guinea pigs suffering from SOM were divided into three groups randomly, 6 for each group. Ectogenic surfactant, dexamethasone and 0.9% sodium chloride solution were injected into guiea pigs' tympanic cavities of group A, B and C respectively. The biochemical components and activity change of surfactant of Eustachian tube were analysed.
