What is ETD?

What is ETD?

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.

Common signs and symptoms associated with persistent ETD include:

  • Chronic pressure in the ears
  • Pain in the ears
  • A clogged or “underwater” feeling
  • Loud hearing of your own voice (autophony)
  • Crackling or popping sounds in the ears
  • Ringing in the ears
  • Muffled hearing

Do I have persistent ETD?

During the past month, if any of these symptoms were either a “moderate problem” or a “severe problem,” it may be time to talk to your doctor.

Only a doctor can determine if you have persistent ETD. To help you start the conversation, download a Patient Questionnaire or find a trained doctor near you.
