Objective:
To find mechanism of tinnitus and explore effective treatment for tinnitus.
Method:
The 133 tinnitus patients were assigned into two groups by relationship between Distortion product otoacoustic emissions and frequencies of tinnitus: relationship group (73 cases) and non-relationship group (60 cases). All 133 cases were treated with drug, such as injection of Lipo PGE1, Vitamin B1 and Vitamin B12. After 14 days of treatment the efficacy of the medicines in two groups was observed.
Result:
The effective rate of two groups mentioned above were 75.3% and 36.7% respectively (P < 0.01). Furthermore, effective rate was correlative to the course of the tinnitus.
Conclusion:
Drug therapy can be a choice for patients who have relationship between DPOAEs and frequencies of tinnitus, especially for acute tinnitus. Personalized treatment should be provided.
