OBJECTIVETo compare different therapeutic effects between single usage of acupoints of Shaoyang meridian and the routine ones for treatment of Bell palsy in acute stage.

METHODSOne hundred and twenty cases with Bell palsy during the first three days were random divided into an observation group and a control group, 60 cases in each group. In observation group, acupoints of Shaoyang meridians were used from the 3rd day till the 14th day, Fengchi (GB 20), Yifeng (TE 17), Wangu (GB 12) at the affected side etc. were selected, after the 15th day, the routine acupoints were applied, Hegu (LI 4) on both sides, Fengchi (GB 20), Quchi (LI 11), Yangbai (GB 14) at the affected side etc. were selected; the control group were treated with the same acupoints as the routine ones in observation group since the 3rd day. And both two groups were treated with oral administration of Prednisone. House-Brackmann (H-B) functional grading of facial nerve on the 3rd day with the one of the 60th day as well as electroneurography (ENoG) on the 3rd day with the one of the 14th day were compared respectively.

RESULTSThe H-B grading improvement and cured rate were 95.0% (57/60) in observation group, which were suprior to 83.3% (50/60) in control group; the cured time in observation group was (34.21 +/- 8.026) days, significantly shorter than (42.78 +/- 9.029) days in control group (P < 0.05).

CONCLUSIONOn the basis of oral administration of Prednisone, single usage of acupoints of Shaoyang meridian in acute stage can make great improvement for recovery of Bell palsy, better than routine point selection.
