Eustachian tube dysfunction (ETD) is the failure of the Eustachian tube (a passage that leads to your middle ear) to open and/or close properly. The Eustachian tube may be narrowed or clogged. This can lead to symptoms such as muffled hearing, ear plugging sensation, pressure in the ear, ringing in the ear, and trouble equalizing the ears during air travel or while diving under water. The surgeons at the Ann Arbor Sinus Center are trained to perform a procedure called eustachian tube dilation. If you have the symptoms discussed above you may benefit from this procedure and you should ask your surgeon if you are a good candidate.
