RESUMO
<p><b>OBJECTIVE</b>To observe the therapeutic effect of electroacupuncture for treatment of sudden hearing loss and to compare with western medicine therapy.</p><p><b>METHODS</b>Sixty cases were randomly divided into an electroacupuncture group and a medication group, 30 cases in each group. The electroacupuncture group was treated with electroacupuncture at Tinghui (GB 2), Yifeng (TE 17), Hegu (LI 4), Xiaxi (GB 43), Zhongzhu (TE 3), etc. and the medication group with intravenous dripping of 6% low molecule dextran 500 mL with ATP and coenzyme A, and oral administration of Nimodipine, Gold Theragan. Whole blood specific viscosity, plasma specific viscosity, hematocrit and fibrinogen before and after treatment and their therapeutic effects were observed.</p><p><b>RESULTS</b>The total effective rate was 86.7 in the electroacupuncture group and 60.0% in the medication group with a significant difference between the two groups (P<0.05), the former being better than the latter; there were significant differences in whole blood specific viscosity, plasma specific viscosity, hematocrit and fibrinogen before and after treatment in the electroacupuncture group (P<0.05), and with no significant difference in the medication group (P>0.05) before and after treatment, and with a significant difference in whole blood specific viscosity, plasma specific viscosity and fibrinogen between the two groups (P<0.05).</p><p><b>CONCLUSION</b>Electroacupuncture has a significant therapeutic effect on sudden hearing loss, which is better than that of the medication, and the mechanism is possibly related with regulative action on indexes of blood rheology.</p>
