The Clinical Efficacy Of Acupuncture Treatment Of Bell Palsy At Acute Stage (wind-heat Type) Are Observed

Purpose: 1. Make know of the pathogens of the peripheral facial paralysis and the differentiation of Bell's palsy by epidemiology survey. 2. Probe into the differential method of Bell's palsy and evaluate the curative treatment effectiveness, safety of Bell's palsy (Wind Heat type) with acupuncture plus bleeding method.Method: 1. Epidemiology survey: Investigate the cause of acute peripheral facial paralysis and differential diagnosis of acute Bell's palsy from April, 2005 to March, 2006. 2. Clinical research: Usage of random numerical chart to randomize experimental cases according to medical condition into an experimental group (acupuncture plus bloodletting treatment) and a control group (conventional acupuncture treatment). The experimental group treatment lasted 4 weeks and consisted of 30 cases. Acupoints: Zanzhu (BL 2), Sizhukong (SJ 23), Sibai (ST. 2), Yangbai (G.B 14), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Yingxiang (L.I. 20), bilateral sides of Hegu (LI 4), Waiguan (SJ 5), Erjian (LI 2), Guanchong (SJ 1), all on the Afflicted side. Needling techniques: Take prone position using conventional sterilization method. In the first course, the patients are treated once every day with even method and shallow depth on the face. Hegu is needled 1 cun with reducing method. Erjian and Guanchong are bleeded 8~10drops with three-edged needle. Retain the needles for 30 minutes and reduce Hegu every 10 minutes. From the 2nd to the 4th course, the patients take a rest after every course. The acupoints on the face should be deeper than the first course. Yangbai to Yuyao, Zuanzhu to Yuyao, Sizhukong to Yuyao, Dicang and Jiache to each other, Yingxiang to Shangyingxiang, Quanliao punctured 0.8~1.2 cun perpendicularly are all manipulated with even method. Hegu is needled perpendicularly with reducing method. Erjian and Guanchong are no longer bleeded. Retain the needles for 30 minutes and reduce Hegu every 10 minutes, one treatment every other day.facial acupuncture points use. Use of even movement, selection of remote points, and reducing method. Prick Erjian (L.I. 2) and Guanchong (S.J. 1) with three-edged needle for bloodletting. Onset of disease after 1 week, local points can use transverse method and retain needle for 30 minutes. During period of treatment the patient rests for 2 days. 1st phase of treatment is administered once a day and the 2nd phase of treatment is administered once every other day.Observation indicatrixes: the main symptoms and signs of facial paralysis. Refer to the 5th International Facial Neurosurgery Symposium recommended House Brackmann (H-B) facial nerve grading scale to process differing levels of severity. The main symptoms include the following 10 indicatrixes: depth of forehead wrinkle, size of rima oculi, change of nasolabial groove, aslant mouth, air leak from the cheek, retained food in the cheek, impairment of taste, hyperacusis, lachrymation, eye muscle reflex. Test the blood before and after two courses of treatments. The effect is judged according to the 5th International Facial Neurosurgery...
