From a recent Cochrane review, the available moderate- to high-quality evidence from randomised controlled trials showed significant benefit from treating Bell’s palsy with corticosteroids. Only 1 in 10 patients treated with corticosteroids will not recover fully (95% CI 6 to 20).
Bell’s palsy (BP) is an idiopathic paralysis of the facial nerve and is the most common cause of lower motor neuron facial palsy. Treatment consists of prednisone 60-80 mg per day for one week. In addition, eye care in patients with BP must be a priority. The prognosis of BP is excellent, with 85% of patients regaining function within three weeks.
