Facial paralysis can be divided into two categories: peripheral facial paralysis, namely facial neuritis, and central facial paralysis. The former is mainly caused by non-characteristic inflammation of facial nerve, while the latter is generally secondary to cerebrovascular accident or intracranial inflammation and tumor. The sequelae of facial neuritis mainly include hemifacial spasm, hemifacial joint movement, crocodile tear syndrome and so on. You can continue to use B vitamins, acupuncture, traditional Chinese medicine physiotherapy and other treatments. People with hemifacial spasm can be treated with carbamazepine and local injection of botulinum toxin A. Secondly, surgical treatment can also be performed, such as facial nerve-accessory nerve and facial nerve-hypoglossal nerve anastomosis. The sequelae of facial paralysis can be gradually recovered through some physical therapy and acupuncture physiotherapy. Facial paralysis is a disease characterized by facial expression and muscle movement disorder caused by many reasons. Its clinical manifestations are facial paralysis, disappearance of forehead wrinkles, enlargement of eye fissure, flat nasolabial groove and drooping corners of the mouth. The affected side should not frown, close eyes, inflate or pout. When eating, food residues often stay in the gap between the teeth and cheeks of the affected side, often accompanied by saliva dripping from this side. Pay attention to your physical condition in your life, seek medical attention in time if there is any abnormality, and don't abuse drugs.
