Distinguish between vestibular neuritis and labyrinthitis in terms of audiometric findings and clinical presentation.

Explanation:
Whether hearing is affected is what distinguishes vestibular neuritis from labyrinthitis. Vestibular neuritis results from inflammation of the vestibular nerve and causes vertigo and balance problems while cochlear function remains intact, so audiometric testing is normal and there are no cochlear symptoms like tinnitus. Labyrinthitis extends to the cochlea, so the vertigo is accompanied by measurable hearing loss on an audiogram and often tinnitus with a sense of fullness in the ear. This cochlear involvement explains why hearing loss and tinnitus appear in labyrinthitis but not in vestibular neuritis. Therefore, vertigo with intact hearing points to vestibular neuritis, while vertigo with hearing loss and tinnitus due to cochlear involvement points to labyrinthitis.
