[The evaluating time of curative effect on sudden deafness].
OBJECTIVE
To explore the best evaluating time of curative effect on sudden deafness so that the curative effect on sudden deafness can been evaluated more exactly and literally.


METHODS
Pure tone audiometries in 112 cases of sudden deafness were performed on the pretreatment day and on the third, seventh, fourteenth post-treatment day, and in the first, second, third, fourth post-treatment month. All of acoustical data were analyzed.


RESULTS
The total effective rates were statistical different between the third, seventh post-treatment day and the fourteenth post-treatment day, the first, second, third, fourth post-treatment month. There were no statistical difference between the fourteenth post-treatment day and the first post-treatment month. There were statistical difference between the fourteenth post-treatment day and the second, third, fourth post-treatment month. The total effective rates were no statistical difference between the first and the second, third, fourth post-treatment month but it was fluctuated in the first post-treatment month. The total effective rates were no statistical difference between the second and the third, fourth post-treatment month and it was changeless on the second post-treatment month. From the curve of recruitment of hearing in different time, the curve of the total effective rates ascend from the third post-treatment day, then get to plateau from the second post-treatment month. If the cure rates, the efficiency rates, the effective rates in different time were analyzed, respectively, the hearing improvement ascend in first two weeks then. Hearing improvement get to plateau from fourteenth post-treatment day.


CONCLUSIONS
(1) The evaluated results of curative effect to sudden deafness correlated vary in different time point post-treatment. (2) Prognosis can be predicted approximately 2 weeks after treatment. Patients who recover acoustic sensibility within 2 weeks have more significant improvement than the patients who hearing improvement after 2 weeks treatment. (3) The results of curative effect are stable after 2 months. If the data of this time were adopted, it would be more objective and accurate to evaluate the curative effect on sudden deafness.
