What is the most common cause of tinnitus?

• A. Conductive hearing loss
• B. Sensorineural hearing loss
• C. Age-related hearing loss
• D. Otitis media

Answer: (B)

Tinnitus most often arises when there is reduced input from the inner ear, specifically sensorineural hearing loss. Damage to cochlear hair cells or the auditory nerve—whether from aging (presbycusis) or noise exposure—decreases the signal reaching the brain. In response, central auditory pathways increase their gain, which can generate the perception of sound in the absence of external input. Conductive hearing loss and middle-ear disorders can be associated with tinnitus, but they are less commonly the primary drivers. Otitis media is an infection of the middle ear and isn’t the typical cause of chronic tinnitus. So sensorineural loss is the most common underlying factor for tinnitus.
