Patient's question:
Previously, Grandma's health was still good, but when she woke up this morning, she suddenly felt unwell, especially on her face. It turned out that Grandma's mouth was twisted and her eye corners were also slanted upwards. After a careful examination, she was diagnosed with facial paralysis. It's unclear how she contracted this disease. What kind of help is needed: What are the specific causes of facial paralysis?Doctor's answer:
Bell's palsy is caused by the blood vessels that supply the facial nerve being affected by cold wind or cold water, leading to severe pain, resulting in brain edema, swelling, compression of nerve tissue, and blood stasis. Most patients experience cold wind or cold water exposure on the affected side of the head before the onset of the disease, such as from using a fan or encountering cold water. A smaller portion of patients show signs of viral infection before or after the onset, commonly experiencing symptoms like colds or ear infections. It is recommended to seek follow-up treatment promptly and actively.
