Tubomanometry and EarPopper Devices for Eustachian Tube Function Testing

The Eustachian tube (ET) is a biological tube that links the middle ear to the back of the nose and throat. It has several functions, of which the most important is to maintain optimal middle-ear health. Eustachian tube dysfunction (ETD) can result in pain or a popping sensation in the ears when flying in an airplane or going up a tall building in an elevator. Many people with ETD also suffer from ear problems such as repeated middle-ear infections or fluid in the ears. However, there are very few easily-administered tests to measure and assess Eustachian tube function (ETF). Tubomanometry is one of these tests, however it is expensive and used to measure ETF only in research settings. In this study, the investigators propose that using a combination of two readily available devices, the EarPopper and a tympanometer, will work in a manner similar to a Tubomanometer to test ET function.
