Eustachian Tube Function Testing using an Acoustic Impedance Bridge.

Abstract

A procedure for comprehensive testing of eustachian tube function was devised. The test battery was administered to 13 apparently normal subjects, 5 subjects with clinically identified eustachian tube malfunction, and 3 subjects who had experienced ear blocks in an altitude chamber. Results were examined to find what, if any, portions of the test might predict ability to undergo rapid barometric pressure change without experiencing ear block. Neither the whole nor any portion of the procedure was found suitable for screening purposes. However, the tests appear useful in clinical evaluation of eustachian tube function. (Author)
