Result: The total effective rate was 80.00% and 90.91% in control group and treatment group respectively. The clinical efficacy in treatment group was significantly superior to that in control group(P < 0.05). The symptom disappearance rate of treatment group was significantly higher than that of control group(P < 0.05). The hearing loss value and pure tone threshold value in treatment group after treatment were significantly lower than those in control group and before treatment (P < 0.05). The level of tinnitus grading state in treatment group after treatment was significantly higher than that in control group and before treatment(P < 0.05).
