Facial neuritis is not contagious, but can be caused by viral infections or idiopathic facial nerve paralysis. Clinically, cold or wind stimulation is a factor that triggers facial neuritis, and the incidence of facial neuritis is usually significantly higher in winter than in other seasons. Facial neuritis will lead to inflexibility of facial muscle movement, which is manifested by shallow forehead lines and nasolabial folds, crooked corners of the mouth, leakage of wind in speech, and leakage of air in the cheeks, etc. Moreover, the patient will lose the random movement of the face on the opposite side of the focal point, but the patient’s mouth will be inclined to the healthy side when he/she does the tooth showing action. The treatment of facial neuritis, in the acute stage, should be selected according to different causes, and can be given to the patient using hormones, nutritive drugs for facial nerve treatment. If the patient has a viral infection, acyclovir can be used for antiviral treatment.
