Question
What are the symptoms of facial paralysis?
Answer
The main symptoms of facial paralysis include discovering abnormal function on one side of the face during morning grooming, such as drooping mouth corners, inability to close eyes, and complete weakness of facial expression muscles. In severe cases, when the patient shows their teeth, the forehead wrinkles disappear, the eye fissures widen, the nasolabial grooves flatten, and the mouth corner on the affected side droops towards the healthy side. Functions such as frowning, closing eyes, and blowing a whistle are all affected on the side of the lesion because the lips on the affected side cannot be tightly closed, leading to air leakage.
