The symptoms of facial paralysis can be summarized as follows: the first type is forehead lines, and some patients will disappear and become shallow, usually unilateral. Followed by eyebrows, one side is high and the other is low. The third is the eyelid, which is incomplete and the lower eyelid droops. The fourth is abnormal facial sensation, numbness and poor sensitivity to pain. Fifth, the nasolabial groove becomes shallow, the corners of the mouth tilt to the healthy side, and the function of exposing teeth decreases. The sixth experiment is the cheek drum experiment, which is called "cheek drum experiment". Simply put, keep your mouth as close as possible, and then leak when blowing. Most patients will have partial eclipse and food when eating.

Yang Yining suggested that if you suffer from facial paralysis, you should go to a neurology department for treatment.
