Patient's question:
Approximately three months ago, due to a sudden lack of physical fitness training, I experienced sudden nosebleeds and, after undergoing treatment, had a cold for over two hours, which led to facial paralysis for three and a half months. Now it's basically recovered. If I forcefully close my left eye, new problems may reappear. What are the causes of peripheral facial paralysis?Doctor's answer:
Peripheral facial paralysis is caused by damage to the facial nerve nucleus or the facial nerve itself, and all cases of facial nerve paralysis occur on the same side as the inflammation. From the forehead upwards, there is no wrinkling, the cornea is not protected, the nasolabial fold disappears, the teeth, cheeks, and mouth corners are distorted (or the angle of inflammation shifts to the other side, causing the opposite side of the collapsed facial muscles). The majority of peripheral facial paralysis is caused by cold, ear infections, meningitis, or neurofibromatosis. Additionally, 2/3 of the tongue anteriorly experiences taste disturbances, and speech becomes unclear.
