Patient's question:
My husband woke up this morning to drink water and suddenly found he couldn't open his mouth wide and his speech was also unclear. I quickly took him to the hospital for treatment. The doctor said my husband had facial paralysis. What are the causes of facial paralysis? Why did this happen?Doctor's answer:
Causes of Bell's Palsy:1. The blood vessels that supply nutrients to the facial nerves are spasmed due to cold wind or cold, leading to ischemia, edema, and compression of the nerve tissue, resulting in the disease.
2. Most patients had exposure to cold wind, cold water, or other stimuli on the affected side before the onset of the disease, such as using a fan or encountering cold water.
3. A small number of patients showed signs of viral infection before or after the onset of the disease, commonly suffering from symptoms like colds or ear infections.
