Patient's question:
Doctor, my sister got facial paralysis when she was only three years old. She has been taking medicine for treatment, but how did the facial paralysis come about?Doctor's answer:
Bell's palsy is divided into central facial palsy and peripheral facial palsy. Central facial palsy is mainly caused by facial paralysis symptoms due to central nervous system inflammation. Generally, a head CT scan is required for a thorough examination to aid in diagnosis. Peripheral facial palsy is most commonly caused by facial nerve neuritis, usually resulting from physical damage to the facial nerve or viral infection. If this condition is present, anti-inflammatory and neuroprotective drugs are generally required for treatment to stabilize nerve metabolism.
