Corticosteroids for the treatment of idiopathic acute vestibular dysfunction (vestibular neuritis).

Idiopathic acute vestibular dysfunction (vestibular neuritis) is the second most common cause of peripheral vertigo after benign paroxysmal positional vertigo (BPPV) and accounts for 7% of the patients who present at outpatient clinics specialising in the treatment of dizziness. The exact aetiology of the condition is unknown and the effects of corticosteroids on the condition and its recovery are uncertain.
