Facial palsy can be categorized into peripheral facial palsy and central facial palsy. Most of the peripheral ones are relatively easy to treat and even self-healing, while the difficulty in treating central facial palsy is related to the underlying disease. Peripheral facial palsy is caused by damage to the facial nerve nucleus of the brainstem and the facial nerves emanating from it, resulting in symptoms such as crooked corners of the mouth, shallow or disappearing frontal lines, and inability to close the eyes completely, etc. It can be cured by a combination of traditional Chinese and Western medical treatments. In the acute stage, drugs such as dexamethasone, acyclovir and vitamin B12 can be taken as prescribed by the doctor, and in the recovery stage, the blood circulation can be improved with TCM acupuncture and infrared irradiation, etc. Most of the patients can be fully recovered within 2~3 months, and very few of them will be left with after-effects. Central facial paralysis is generally associated with cerebrovascular diseases such as cerebral infarction and cerebral hemorrhage, and the difficulty of treatment is also closely related to the severity of the underlying disease. If the infarction area is large, or the condition is critical, it is generally more difficult to treat, and it is easy to leave sequelae such as crooked corners of the mouth and choking on water. If the primary disease is not treated in time, the prognosis is generally poor. If symptoms such as slanting of the corners of the mouth and change of forehead lines are found, timely treatment should be carried out to avoid delaying the condition.
