Abstract
It has been postulated that there is a surface active agent (SAA) in the Eustachian tube which normally facilitates tubal opening but which may be inactivated by infection, resulting in poor tubal function. The present experiment was an attempt to demonstrate the effect of this surface active agent by measuring changes in Eustachian tube opening pressure following removal of the suspected tubal surface active agent by saline. To make these measurements, air or normal saline was injected into the middle ear of 15 fresh guinea pig temporal bones until pressure was sufficient to open the Eustachian tube.
