We reviewed 182 patients with sudden hearing loss at our hospital to investigate the effect of oxygenation at high pressure (OHP).<BR>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).<BR>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.<BR>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.<BR>In patients with initial hearing levels up to 60 dB, high age, vertigo, the improvement rate was significantly high at OHP group.<BR>But in patients received the treatment over 14 days after onsets, there was no difference between OHP group and non-OHP group.<BR>We conclude that the addition of OHP is effective for primary sudden hearing loss.
