In some cases, inflammation of cranial nerves accompanies acute labyrinthitis. Which cranial nerve is most likely to be affected
Roman55 [17]
The cranial nerve most likely to be affected hat is evidenced by acute labyrinthitis is the EIGHTH Cranial Nerve named Vestibulocochlear.

Vestibulocochlear nerve dysfunction can cause hearing loss, vertigo, or tinnitus. The dysfunction is a result of the damage in either the cochlear or vestibular portion of the eighth cranial nerve. Damage is  between the inner ear and its entry into the brainstem at the pontomedullary junction.

Vestibular neuritis is also identified as labyrinthitis, vestibular neuronitis, and acute peripheral vestibulopathy.
