What is Patulous eustachian tube, the disorder affecting Celine Dion?
The hearing condition that has caused Quebec pop star Celine Dion to cancel some upcoming Las Vegas shows is known as Patulous eustachian tube. So just what is it and why does it occur?
Patulous eustachian tube is a disorder in which the channel that runs between the middle ear and back of the nose and throat stays open. Normally, these eustachian tubes remain closed and open only occasionally to regulate air pressure around the ear drum. A valve near the opening into the middle ear controls this process.
Sneezing, swallowing or yawning causes the valve to open, which keeps air pressure and fluid from building up inside the ears. Descending in an aircraft can also affect the function of the valves and eustachian tubes, leading to a pressure build-up that muffles hearing and sometimes causes pain.
