Peripheral facial paralysis is a frequently encountered disease with a high incidence, and it is one of the most common diseases in acupuncture and moxibustion treatment. Because there are rich literatures in clinical studies on acupuncture and moxibustion treatment for this disease, and clinically, it is divided into different stages, in the present paper the current situation of clinical studies about acupuncture and moxibustion treatment for peripheral facial paralysis according to different stages in resent years are analyzed and evaluated including the stage division, the optimal time for treatment, location of injured nerves and assessment of the therapeutic effect, etc. 1. Current Situation of Treatment Studies Peripheral facial paralysis is induced often by inflammation, viral infection, trauma, intracranial and extracranial tumors, and lesion of pons or medulla oblongata. Clinically, facial paralysis induced by edema of facial nerves and myelin sheath caused by non-suppurative inflammation in facial canal, i.e., Bell’s palsy, is the mostly common accounting for about 60% of peripheral facial paralysis.1 People of any ages may be attacked with the disease, with most encountered in young people and middle-aged. In our country, the incidence is higher, at present it is 38.0 / 100 thousand in city and 2.6.0 / 100 thousand in rural area.2

Peripheral facial paralysis is characterized by disappearance of frontal stripes to varying degrees on the affected side, weakness in knitting the brows, failure of eyelid closure, unable to shrug the nose, the nasolabial groove becoming shallow, the nasolabial groove and the lip slanting towards the healthy side, corner of the mouth on the affected side decreasing, the food retaining in the mouth cheek. A part of patients is possibly accompanied with facial numbness, lachrimation in the affected eye, pain or tenderness on the retroauricular mastoid process, hypogeusesthesia on the anterior 2 / 3 of the tongue, dry mouth, dizziness, tinnitus, hypoacusis or audition hypersensitivity, and at the late stage, facial stiffness of varying degrees or convulsion can be seen on the affected side. 3 Because the cause of disease and pathogenesis for this disease have not been completely explained yet, at present, western medicine mainly adopts medication and operation therapy, until to now, there are no special and effective therapeutic methods for it. Cortical hormone treatment, anti-virus treatment, angiectasis therapy, vitamin treatment, massage, functional training and facial nerve decompression, facial nerve anastomosis and face-lifting operation, and so on are often used. At present, it is in common held that the therapeutic effect is still difficult to be affirmed and it is tried out only for severe cases, 4 so

it is difficult to be popularized clinically. Acupuncture and moxibustion treatment of this disease have a long history, and clinical practice of a long period and a large number of literature reports hold that acupuncture and moxibustion treatment of facial paralysis have an unique clinical therapeutic effect. Acupuncture-moxibustion therapy was formally enrolled in The General Medical Program Coding edited by The American Medical Society in January 1998, considering that it is a regular and effective therapy for facial paralysis. 5 Clinically, filiform needle method and moxibustion are mainly used in acupuncture and moxibustion treatment of facial paralysis, and electroacupuncture, cupping, acupoint injection, acupoint application and comprehensive therapy, etc. also are commonly-used methods. Because clinically peripheral facial paralysis has the acute stage, the resting stage and the restoration stage, and the pathological changes of the lesion at the different stages are different. In recent years, there are no less research literatures about acupuncture and moxibustion treatment of peripheral facial paralysis by selecting stage or by stages. Most reports hold that treatment by stages has better effect than not by stages. For example, WANG Su-fang6 randomly divided the patients into two groups, the patients of the treatment group were divided into 3 stages according to duration of illness and treated respectively with different therapies, at the attack stage (1–7 days of attack) were treated with acupoints on The Yangming Channels as main; at the resting stage (8–20 days of attack) with penetration needling as main, and at the restoration stage (after 20 days of attack) with deeply needling combined with massage; And the patients in the control group were treated with acupuncture at acupoints on The Yangming Channels as main, in combination with radiation at the local part with far-infrared therapeutic unit. The results indicated that in the treatment group the therapeutic effect was better and the therapeutic course was shorter as compared with the control group (both P
