Patient's question:
I have a friend who got facial paralysis recently. The corners of his mouth are drooping, and his face is asymmetrical on both sides. He even drools when he speaks. I don't understand how he could suddenly get facial paralysis, so I'm curious and also want to know some of the causes of this condition.Doctor's answer:
Hello,1. Inflammatory lesions: Inflammatory lesions are often caused by the activation of dormant varicella-zoster virus (VZV) that has been latent in the facial nerve sensory ganglion.
2. Otologic diseases;
3. Bell's palsy;
4. Tumors;
5. Neurogenic;
6. Traumatic;
7. Toxicity: such as alcohol toxicity. Long-term exposure to toxic substances;
8. Metabolic disorders: such as diabetes, vitamin deficiencies;
9. Vascular insufficiency;
10. Congenital facial nerve nucleus developmental defects.
