Which type of hearing loss is caused by problems in the outer or middle ear and can often be fixed medically or surgically?

• A. Sensorineural
• B. Mixed
• C. Central
• D. Conductive

Answer: (D)

Understanding which type of hearing loss is caused by problems in the outer or middle ear and can often be fixed medically or surgically starts with where the problem is located. When sound can’t be conducted properly through the outer or middle ear to the inner ear, that’s conductive hearing loss. Common causes include earwax blockage, fluid behind the eardrum, a perforated eardrum, or issues with the tiny middle-ear bones. Because the issue is mechanical and localized to the ear’s structure, many cases respond to treatment or procedures that restore the sound pathway: removing wax, treating infection, placing tubes for fluid, repairing the eardrum, or reconstructing the ossicles.

By comparison, sensorineural hearing loss comes from damage to the inner ear or auditory nerve, which is not typically fixable with the same kinds of ear procedures. Central hearing loss involves brain processing, not the ear itself. Mixed hearing loss includes both conductive and sensorineural components, so fixing the conductive part may help, but the sensorineural part remains and may require different management.
