Patient's question:
Facial paralysis is a relatively common condition, which can cause significant inconvenience to patients. My brother-in-law is 40 years old now. I wonder which side of the face is usually affected by facial paralysis?Doctor's answer:
Bell's palsy does not have a side that is more prone to occur than the other. The anatomical structures of the facial nerves on both sides of the body are the same, and the likelihood of onset is the same on both sides. Which side may recur is random. Inflammation is also an important cause of facial paralysis. When a patient's head is infected for some reason, such as by bacteria or viruses, and these bacteria or viruses cause significant damage to the facial nerve, it can also lead to facial paralysis. When the nerve tissue is interfered with, it is also prone to recurring facial paralysis. Common causes include acute or chronic middle ear infections. If middle ear infections are not treated properly, they can cause damage to the facial nerve tissue.
