The NGF Point-Injection for Treatment of the Sound-Perceiving Nerve Deafness and Tinnitus in 68 Cases

Objective To observe the therapeutic effects of the point-injection with nerve growth factor (NGF) for the sound-perceiving nerve deafness and tinnitus. Methods The 140 cases in this series were randomly divided into a treatment group of 68 cases treated by NGF injection at the points of Yifeng (TE 17) and Wangu (GB 12), and a control group of 72 cases orally taking Xibiling () and adenosine triphosphate (ATP) and intramuscular injection with VB1 and VB12. Results The total effective rate was 78.6% in the treatment group and 31.8% in the control group, with significant difference between the two groups (P Conclusion For treating nervous deafness and tinnitus, NGF point-injection may show good therapeutic effects, but inversely proportional to the illness course, age and the extent of hypoacusis.
