Question
What causes hemifacial paralysis?
Answer
Hemifacial paralysis may be caused by viral infections, such as mumps or herpes zoster viruses. Additionally, immune system issues, like Guillain-Barré syndrome, can also lead to hemifacial paralysis. Moreover, blood circulation problems, such as small vessel spasm or thrombosis, may trigger hemifacial paralysis. In some cases, hemifacial paralysis may be caused by intracranial tumors or trauma. The treatment method depends on the cause and may include medication, physical therapy, or neurosurgical procedures.
