Facial palsy, i.e. facial neuritis or idiopathic facial nerve palsy, is known in Chinese medicine as “seclusion of the mouth” and “crookedness of the mouth and eyes”. The onset of the disease is sudden, and the child usually wakes up in the morning and finds that one eye cannot be closed, the mouth is tilted to one side, he cannot rinse his mouth, and the face is swollen or has a pulling sensation. There is often pain under the ear or mastoid, loss of facial expressions, loss of forehead wrinkles, incomplete eye closure, enlarged eye fissures, eyelid ectropion, inability to do such actions as frowning, frowning, showing teeth, cheek puffing, pouting and whistling. The nasolabial folds become shallow or skewed, the speech leaks, the corners of the mouth salivate, and the food often stays between the cheeks on the sick side when eating. According to Chinese medicine, the main cause of facial palsy is that the facial vasculature is empty, and the wind-cold evil is repeatedly felt, and the deficient wind invades the Yang Ming and Shao Yin vasculature, resulting in the blockage of the meridian qi, the loss of nourishment of the tendons, and the onset of the disease. Modern medicine believes that this disease is mostly caused by acute non-purulent facial neuritis in the stem mastoid foramen, psychological factors are also an important factor in the development of the disease, often physical fatigue, lack of sleep, mental tension and physical discomfort.
