Correlation between effectual time and the curative effect in patients with all frequency descending sudden deafness after treatment.

Abstract

To discuss the correlation between effectual time and the curative effect in patients with all frequency descending sudden deafness. According to effectual time, the subjects were divided into first week effectual group and second week effectual group and the curative effect of each group was compared. In patients with flat descent sudden deafness, the curative rate of the first week effectual group was higher than that of the second week effectual group, but there was no significant difference between the two groups (χ2 = 1.584, P = 0.208). Meanwhile, the total significant effective rate of the first week effectual group was higher than that of the second week effectual group, without obvious difference between the two groups (χ2 = 0.227, P = 0.634). Furthermore, in patients with total deafness type of sudden deafness, the curative rate of the first week effectual group was higher than that of the second week effectual group, showing no remarkable difference between the two groups (χ2 = 2.726, P = 0.099). Besides, there was no remarkable difference in the comparison of the total significant effective rate (χ2 = 2.933, P = 0.087), which was higher in the first week effectual group than that in the second week effectual group. The course of treatment should be at least 2 weeks in patients with all frequency descending sudden deafness after onset.
