Which symptom is most associated with Eustachian tube dysfunction causing fullness and muffled hearing?

• A. Dizziness
• B. Tinnitus
• C. Severe ear pain
• D. Ear fullness or pressure with muffled hearing

Answer: (D)

When the Eustachian tube isn’t venting properly, the middle ear can’t equalize its air pressure with the outside environment. This creates negative pressure in the middle ear, pulling the tympanic membrane inward and reducing its ability to vibrate. The result is a sensation of fullness and muffled hearing—the classic sign of Eustachian tube dysfunction. Dizziness points to a vestibular issue, severe ear pain suggests acute infection or trauma, and tinnitus can occur but isn’t the defining feature of ETD. So ear fullness or pressure with muffled hearing best reflects the effect of ETD on hearing.
