Question
My husband woke up this morning to drink water and suddenly felt that he couldn’t open his mouth wide, and his speech was also slurred. The doctor said he has facial paralysis. What are the causes of facial paralysis?
Answer
The causes of facial paralysis may include: 1. Vascular spasm in the facial nerves due to wind and cold, leading to ischemia, edema, and compression of nerve tissue, causing the condition. 2. Most patients have experienced cold wind or cold water stimulation on the affected side before onset, such as using a fan or encountering cold water. 3. A small number of patients show signs of viral infection before or after onset, commonly suffering from symptoms like colds or otitis media.
