Facial neuritis is generally prone to occur in patients with immune dysfunction, with factors such as viral infections and some patients may be related to cold stimulation from air conditioning or fans on the face. The treatment of facial neuritis mainly includes the following aspects: First, glucocorticoid treatment should be given. Glucocorticoids play a very important role in the treatment of facial neuritis. They can reduce abnormal inflammatory responses and swelling of the facial nerve, which greatly helps the patient's recovery. Second, some B vitamins should be given to nourish the nerves. If the condition is caused by viral infection, antiviral medication should also be provided. In addition, some rehabilitation training is particularly important, and it is recommended that patients receive early physiotherapy and functional training for facial muscles.
