Question
What are the specific causes of facial paralysis?
Answer
Facial paralysis occurs when the blood vessels nourishing the facial nerves are subjected to severe pain due to wind and cold, leading to brain edema, swelling, and pressure on the nerve tissue, resulting in hemorrhagic disease. Most patients experience cold wind or cold water stimulation on the affected side of the head before the onset of the disease, such as blowing a fan or encountering cold water. A small number of patients show signs of viral infection before or after the onset, with common symptoms including colds and otitis media. It is recommended to consult a doctor promptly and receive active treatment.
