What differentiates vestibular neuritis from labyrinthitis?

The distinguishing feature between vestibular neuritis and labyrinthitis lies in the associated auditory symptoms. Vestibular neuritis primarily affects the vestibular system and is characterized by vertigo, loss of balance, and other vestibular symptoms without any auditory involvement. In contrast, labyrinthitis affects both the vestibular and auditory components of the inner ear, often leading to sudden hearing loss and tinnitus along with vestibular symptoms.

Sudden hearing loss and tinnitus are hallmark signs of labyrinthitis and are not present in vestibular neuritis. Therefore, identifying the presence of these auditory symptoms is crucial in differentiating between the two conditions. The other options do not pertain to the main differences between vestibular neuritis and labyrinthitis, as nasal polyps, acute ear pain, and clear rhinorrhea are not specific to distinguishing these conditions.
