Viral neuritis causing facial paralysis can be completely restored to normal after 1-2 months of treatment, but the exact time depends on the degree of damage to the patient’s facial nerve, and the recovery time is different for mild, moderate, and severe facial paralysis. 1. For peripheral facial paralysis, if active treatment is given to nourish the facial nerve during the acute stage, and glucocorticoids are applied in the early stage, such as dexamethasone or oral methylprednisolone to reduce the edema of the facial nerve, it is crucial for the recovery of the facial nerve in the later stage. 2. Early application of glucocorticosteroids, such as dexamethasone, or oral methylprednisolone, to reduce the edema of the facial nerve is essential for the recovery of the facial nerve at a later stage. In the acute stage, nutritional treatment should be given to the facial nerve, such as intramuscular methylcobalamin or oral vitamin B12, and after the condition is stabilized, the patient can be helped to recover by means of acupuncture, physiotherapy, etc. 2. In mild facial paralysis, the patient may return to normal after 2 weeks of the disease. In severe facial paralysis, the recovery time may be about 3 months, and in moderate facial paralysis, the patient may recover completely in about 2 weeks to 1 month.
