Some sources consider vestibular neuritis and labyrinthitis to be the same thing (some differentiate based on auditory symptoms)
Background
- Infection of cochlear and vestibular apparatus (from middle ear via round/oval windows)
- Acute suppurative labyrinthitis is only cause of peripheral vertigo requiring urgent tx
- Some sources consider Vestibular Neuritis and Labyrinthitis to be the same thing
- Some differentiate based on auditory symptoms
Clinical Features
- Peripheral vertigo + hearing loss + middle ear findings
- Severity depends on type of labyrinthitis:
- Acute suppurative labyrinthitis
- Caused by extension of infection from otitis media, meningitis, mastoiditis
- Signs of toxicity
- Serous labyrinthitis
- Caused by inflammatory respones to nearby infections (including viral)
- Clinical course similar to Vestibular Neuritis (Neuronitis)
- Acute suppurative labyrinthitis
- Severity depends on type of labyrinthitis:
