Eustachian Tube Testing in a Pressure Chamber -- Validation
This study will compare Eustachian tube function (ETF) testing in adults with intact tympanic
membranes (TM) using a pressure chamber to that obtained using standard methods requiring a
non-intact TM.
membranes (TM) using a pressure chamber to that obtained using standard methods requiring a
non-intact TM.
The investigators propose to introduce new test methods and protocols to our laboratory for
better clinical characterization of Eustachian tube function in ears with intact TM's. These
test will be done in a pressure-chamber and will use previously published and newly developed
methods. Participation will require a minimum of 5 visits to the ENT Research Center, 1 for
myringotomy (putting a small hole in the eardrum) and 4 for ETF testing. Hearing testing will
be done at entry and exit; otoscopy (looking at the ears) and tympanometry (a test done with
an earplug and varying pressures in the ear canal) are done at every visit.
