Question
An ear lost hearing during childhood due to illness, and now the other ear’s hearing is also significantly decreasing. What factors or diseases could be causing this?
Answer
This hearing loss may be related to allergic rhinitis, primarily due to the nasal congestion causing the eustachian tube to be obstructed, leading to a feeling of dullness in the ear and unclear hearing, as well as tinnitus. The possibility of nasal cancer is relatively low.
