Facial palsy can be categorized into central facial palsy and peripheral facial palsy. Central facial paralysis needs to be treated according to the cause, while peripheral facial paralysis needs to be treated with glucocorticoid drugs such as dexamethasone for anti-inflammation, methylcobalamin and vitamin B12 for nerve nutrition. Facial palsy refers to paralysis of the facial nerve and paralysis of the facial muscles caused by various reasons, which may result in symptoms such as crooked corners of the mouth, disappearance of frontal lines, incomplete closure of the eyelids, and shallow nasolabial folds. The treatment of facial paralysis should be differentiated into central facial paralysis and peripheral facial paralysis. Central facial palsy refers to facial muscle paralysis caused by certain intracranial diseases such as cerebral infarction, and its treatment should be directed at the primary disease causing facial palsy, such as cerebral infarction causing central facial palsy need to take antiplatelet aggregation drugs, such as aspirin, clopidogrel, etc.; and need to stabilize plaques with lipid-lowering statin drugs, such as atorvastatin, simvastatin, etc.. Peripheral facial paralysis is mostly caused by non-specific inflammation of the facial nerve. Glucocorticoid drugs such as dexamethasone should be used in the treatment to promote the local inflammation and edema to subside as soon as possible, and at the same time, methylcobalamin and vitamin B12 should be used to nourish the nerves. Physiotherapy and acupuncture should be used to promote the recovery of facial nerve function. Patients with facial paralysis should seek medical treatment in a timely manner and follow the doctor’s instructions for standardized treatment.
