初期治療例における検討

抄録

We reviewed 182 patients with sudden hearing loss at our hospital to investigate the effect of oxygenation at high pressure (OHP).
116 patients received a course of intravenous administration of steroids, ATP with OHP, and 69 patients received a course of intravenous administration of steroids, ATP without OHP (non-OHP group).
The improvement rate was compared between OHP group and non-OHP group according to some prognostic factors: initial averaged five frequency hearing level, age, vertigo, number of days between onset and beginning of the treatment.
The improvement rate was 63.79% in OHP group and 52. 17% in non-OHP group, and in OHP group the improvement rate was significantly high.
In patients with initial hearing levels up to 60 dB, high age, vertigo, the improvement rate was significantly high at OHP group.
But in patients received the treatment over 14 days after onsets, there was no difference between OHP group and non-OHP group.
We conclude that the addition of OHP is effective for primary sudden hearing loss.
