The vestibulocochlear nerve or auditory vestibular nerve, also known as the eighth cranial nerve, cranial nerve VIII, or simply CN VIII, is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain.

What is the auditory canal vestibular nerve?
The vestibular nerve innervates the vestibular system of the inner ear, which is responsible for detecting balance. The cochlear nerve travels to cochlea of the inner ear, forming the spiral ganglia which serve the sense of hearing.

Does the vestibular nerve affect hearing?
The symptoms of vestibular neuritis and labyrinthitis are very similar. However, if your hearing is affected, then labyrinthitis is the cause. This is because inflammation of the labyrinth affects hearing, while inflammation of the vestibular nerve does not.
What happens if cranial nerve 8 is damaged?
CN VIII pathology can result from direct trauma, congenital malformations, tumor formation, infection, and vascular injury. Presenting symptoms include vertigo, nystagmus, tinnitus, and sensorineural hearing loss. Also, the involvement of the facial nerve due to its proximity should not be excluded during evaluation.
