Facial palsy (idiopathic facial neuritis) is a common and frequent disease. When the human body is weak, due to careless regulation, wind evil takes advantage of the weakness to enter the facial meridians, the meridians become blocked and inaccessible, the facial tendons and veins lose nourishment and are sluggish, resulting in difficulty in closing the eyelids and crookedness of the corners of the mouth. Over the past ten years, we have observed and treated thousands of clinical patients and found that regardless of wind-cold or wind-heat patients, there is a feeling of tightness or soreness at the cataract point behind the ear, which is the front lower edge of the affected mastoid process, and the early use of tendon and bone needles at this point to disperse wind and disperse evil and activate the meridians, that is, to loosen and decompress, can greatly shorten the healing process.
