Background: Obstructive dysfunction of the Eustachian tube (ET) is one of the underlying possible causes of pressure sensations in the ear, fluctuating hearing loss, or ringing in the ears. It may also result in different middle ear pathologies. There is no current gold standard for COETD diagnosis. TMM is a semiobjective method to record ET patency.
