[Comparative study of intratympanic Dexamethasone injection for sudden deafness at different time intervals].

Objective

Comparative study of intratympanic Dexamethasone injection for sudden deafness at different time intervals. Method:One hundred and sixty cases which had been diagnosed sudden deafness were treated by vasodilatortrophic nerve drugs and high pressure oxygen and the same time dexamethasone injective in the middle ear. Injection time intervals were divided into qd, qod, and twice a week. Contral group is not use dexamethasone. Result:The cure rate of qd and qod groups were higher than twice a week group, and the difference was statistically significant (P<0.05).

Conclusion

Intratypanic Dexamethasone injection for sudden deafness qd or qod is effective and safe.
