Preservation of hearing in partial deafness patients who received two different regimes of corticosteroid therapy following cochlear implantation: one-year observations

Abstract

Abstract The objective of this study was to assess how different modes of steroid therapy affect hearing preservation in Partial Deafness Treatment group of patients. In this study, the group consisted of 46 (24 women, 22 men; aged 18-78 years) cochlear implant patients divided into 3 subgroups. In the first subgroup (N = 13), patients underwent standard intravenous (IV) steroid therapy following implantation. In the second (N = 16), patients underwent prolonged treatment with a combination of oral and IV corticosteroids. Third subgroup (N = 17) was a control group who received no steroids therapy. The mean hearing preservation rate was 52.1% (SD = 36.7) in patients receiving standard steroid therapy, 71.4% (SD = 22.7) in patients with prolonged steroid therapy, and 22.1% (SD = 33.9) in control patients. The smallest variation of hearing preservation rate was observed in patients with prolonged steroid therapy and was 9.9 dB. In comparison, the mean change in patients with standard steroid therapy was 11.7 dB and for control patients the figure was 18.0 dB. A combination of intravenous and oral steroid therapy seems to be optimal and stabilizes hearing thresholds and preserves hearing.
