Corticosteroids effective in idiopathic facial nerve palsy (Bell's palsy) but not necessarily in idiopathic acute vestibular dysfunction (vestibular neuritis).

摘要

Most authorities would now agree that there is good evidence that corticosteroids are effective in the management of patients with acute idiopathic facial nerve palsy (Bell's palsy) if given early in the condition.The mechanism of action in such settings is believed to be related to their potent anti-inflammatory properties, resulting in decompression of the facial nerve within the temporal bone. What has not been clear up until recently is whether corticosteroids would be equally effective in the management of patients with acute idiopathic vestibul-opathy (vestibular neuritis).
