conduction deafness
Quick Summary
Conduction deafness occurs when there's an interruption in the passage of sound vibrations from the outer world to the inner ear's nerve cells. This blockage can be caused by something as simple as earwax in the ear canal or by stapes fixation, where the stapes bone in the middle ear cannot transmit sound vibrations properly. Unlike nerve deafness, which affects the inner ear's sensory cells or the auditory nerve, conduction deafness is a mechanical issue within the outer or middle ear. This type of hearing loss can sometimes be improved with medical or surgical interventions.12
