Facial paralysis refers to the inflammatory attack on the facial nerve in the extracranial segment, resulting in edema of the facial nerve and causing paralysis of one facial muscle and inflexibility of movement, mainly manifesting as shallow forehead lines, shallow nasolabial folds, air leakage when puffing cheeks, inability to complete whistling, frowning and other actions, and possible storage of rice when eating. In the acute stage, glucocorticoids should be given to reduce the edema of facial nerve and promote the recovery of facial nerve, which are commonly used clinically, such as dexamethasone and methylprednisolone. At the same time, we should give nerve-nourishing drugs, such as methylcobalamin, adenosine cobalamin, vitamin B12 nerve-nourishing symptomatic treatment, and during this period, we should eat a light diet and go out to avoid the natural wind.
