Labyrinthitis, sometimes also called “sudden sensorineural hearing loss with vertigo” in otologic literature, is thought to be due to inner ear damage from a bout of inflammation, though the cause of the inflammation is unknown despite considerable research. Suspicion for labyrinthitis is based on the clinical history and can be supported by findings on physical examination and various otovestibular tests. The standard of care for the symptom of disequilibrium from labyrinthitis is appropriately targeted vestibular rehabilitation therapy, though even with such therapy, not all patients improve.
