Facial palsy is not prone to recurrence after treatment. Facial palsy can be categorized into peripheral facial palsy and central facial palsy, both of which have some possibility of recurrence, but the probability is not high. The most common cause of peripheral facial palsy is idiopathic facial nerve paralysis, which can be caused by viral infection, decreased immunity and other factors. Most patients can be cured and have a good prognosis, and are generally not prone to recurrence, but if the patient is exposed to cold or has not had enough rest for a long period of time, the likelihood of recurrence will be increased. Central facial paralysis is caused by brain lesions, such as cerebral infarction, brain tumor, etc., and is usually difficult to be completely cured. Its recurrence probability is mainly related to the original disease. If facial paralysis reappears, it is usually due to the recurrence of the original disease. In conclusion, after facial paralysis is cured, it is necessary to pay attention to rest and keep the face warm, avoid overwork or emotional fluctuations, and if there is a recurrence of the disease, it is necessary to consult the doctor and get treatment as soon as possible.
