OBJECTIVETo investigate and compare the short-term outcome of patients with low-middle frequency sudden deafness treated with alone or combination treatment.

METHODSFrom August 2007 to October 2011, 205 patients with the diagnosis of low-middle frequency sudden deafness who were from 33 different clinical centers were recruited. All patients were followed up for four weeks from the initial examination. Patients were treated with steroid , Ginaton, batroxobin respectively, or Ginaton and steroid combination treatment.

RESULTSThe total effective rate was 90.73%. In Ginaton group, the total effective rate was 87.27%, 89.19% in steroid group, 87.80% in batroxobin group, and 95.83% in Ginaton and steroid group. Considering the total effective rate, there was no statistical difference between four groups (χ(2) = 7.98, P = 0.54). The clinical cure rate for steroid alone was 81.01%, Ginaton alone 76.36%, batroxobin alone 68.29%, and Ginaton and steroid combination treatment 80.56%. There were no clinically significant differences between the different treatments (P > 0.05).

CONCLUSIONSThe low-middle frequency sudden deafness tends to have a relatively favorable prognosis. The steroid played a good effect in the treatment. But different treatments either improving the microcirculation of inner ear or alleviating edema blood has undifferentiated results. Therefore the combination therapy may be more effective.
