Objective:This study aimed to evaluate the therapeutic effect of intratympanic injection of ganglioside in patients with refractory sudden deafness. Methods:A total of 120 patients with sudden deafness, aged 18-65 years, whose onset was within 11-42 days, failed to respond to conventional treatment, and had an average hearing threshold（500-4 000 Hz）>60 dB were selected. They were prospectively and randomly divided into a control group of 61 cases and an experimental group of 59 cases. The control group was treated according to the recommended protocol of the Chinese Medical Association（postauricular injection of methylprednisolone）, while the experimental group was treated with intratympanic injection of monosialotetrahexosylganglioside sodium+postauricular injection of methylprednisolone. Both groups were simultaneously administered oral ginkgo biloba extract and citicoline tablets. Hearing was re-examined two weeks after the completion of treatment, and the therapeutic effects of the two different treatment methods were compared and analyzed. Results:The effective rate was 29.51% in the control group and 54.24% in the experimental group（P<0.01）. The average hearing threshold improved by 11.57 dB HL in the control group and 22.50 dB HL in the experimental group（P<0.05）. Conclusion:The combination of postauricular injection of methylprednisolone and intratympanic injection of ganglioside is more effective than postauricular injection of methylprednisolone alone in the treatment of refractory sudden deafness. The earlier the treatment, the better the therapeutic effect.

OBJECTIVE: To evaluate the efficiency between two treatments of sudden hearing loss. METHOD: All patients were divided into two groups randomly, basic drug group was treated with ganglioside and vinpocetine injection, combined therapy group was treated with intratympanic dexamethasone and what was used in basic drug group. RESULT: The effective rate of combined therapy group (73.53%) was significantly higher than that of basic drug group (37.78%) (P < 0.05). CONCLUSION The comprehensive therapy of intratympanic dexamethasone injection, ganglioside and vinpocetine injection have excellent efficiency for sudden hearing loss.
