What condition can result from a fistula if hair cells are damaged?

Sensorineural hearing loss is an appropriate answer in this context because it specifically pertains to damage occurring in the inner ear or the auditory pathways leading to the brain, often involving the hair cells located within the cochlea. When a fistula—a pathological connection between the inner ear and the middle ear—occurs, it can lead to fluid dynamics changes that may damage these delicate hair cells. Hair cells play a crucial role in converting sound vibrations into electrical signals, which are then sent to the brain for interpretation. If these cells are compromised, the transmission of sound information is disrupted, resulting in sensorineural hearing loss.

In contrast, conductive hearing loss typically involves problems in the outer or middle ear that prevent sound from effectively reaching the inner ear, such as issues related to the ear canal or eardrum. Tinnitus refers to the perception of noise or ringing in the ears and does not directly relate to the mechanism of hair cell damage. Auditory processing disorder pertains to how the brain processes auditory information rather than a dysfunction in the ear itself. Therefore, sensorineural hearing loss is the most relevant condition resulting from hair cell damage associated with a fistula.
