Facial palsy includes central facial palsy and peripheral facial palsy. Regardless of the cause of facial palsy, if the treatment is not timely or appropriate, there may be sequelae, and the sequelae of facial palsy are more difficult to treat. The most common type of facial palsy is idiopathic facial nerve palsy, which is manifested as peripheral facial palsy. The sequelae can be manifested as paralysis of facial expression muscles on one side, disappearance of frontal lines, inability to frown, incomplete eyelid closure, shallow nasolabial folds, drooping corners of the mouth, drooling, cheek puffing, whistling and air leakage, etc. In the acute stage, oral hormone therapy combined with B vitamins should be used, and if necessary, antiviral drugs such as acyclovir can be added, and physical therapy such as ultrashort wave heat therapy, infrared irradiation or local hot compresses can be performed near the stem mammary foramen, while attention should be paid to protecting the cornea. It is helpful to prevent the emergence of sequelae. Another common cause of facial palsy is cerebrovascular disease, which manifests as central facial palsy. The sequelae of facial palsy are paralysis of the face below the eye fissure, and movements such as eye closure and frowning are not affected. There is a lack of standard treatment plan for the treatment of facial paralysis sequelae, and no unified view has been formed. Chinese medicine scholars have conducted more research and have mostly used acupuncture, electroacupuncture, acupoint injection and other comprehensive treatment methods to treat the sequelae of facial palsy, which also have certain efficacy, but the treatment is more difficult and the course of treatment is slightly longer. In conclusion, facial palsy should be diagnosed early and treated reasonably; once the sequelae are formed, the cure rate will be greatly reduced.
