Facial neuritis, also known as idiopathic facial paralysis, can self-heal in a minority of patients with very mild symptoms without treatment. However, for most patients, it is still recommended to seek treatment promptly as it involves a non-specific inflammatory response. Treatment mainly involves the use of corticosteroids to reduce inflammation and swelling of the facial nerve. Additionally, treatment with B vitamins such as commonly used B1 and vitamin B12 is necessary, as these can nourish the peripheral nerves. Furthermore, patients also need to undergo some physical therapy and rehabilitation training. (Please use medication under the guidance of a professional physician.)
