Abstract
|
|
|
Eustachian tube dysfunction (ETD) is a common condition in clinical otolaryngology practice.
The eustachian tube (ET) is the only pathway connecting the middle ear cavity and thenasopharynx, and has a ventilation function to equalize the pressure of the middle ear and theatmosphere, a discharge function of middle ear secretions into the nasopharynx, and a defensefunction to prevent reflux from the nasopharynx. The most important function of the ET is tomaintain a consistent middle ear air pressure for efficient sound transmission. Various methodshave been used to measure the physiological function of ET. Traditional methods includethe Valsalva, Toynbee, and Politzer test. Physiological methods include the 9-step Bluestoneinflation-deflation test and sonotubometry. Evaluation of ETD using questionnaires is also beingconducted, and currently, imaging tests are also conducted to evaluate the structure of ET.
However, no standard protocols have been established until now. In this article, the types,methods, and advantages and disadvantages of the currently available ET function tests areintroduced
