Abstract
Background and Objectives Steroid treatment is used as a main treatment modality for sudden sensorineural hearing loss (SSNHL). Intratympanic injection of steroid (ITS) has been used and its therapeutic efficacy reported as being comparable to the systemic steroid administration (SS). This study compares the hearing outcomes of using ITS and SS simultaneously and SS alone.Subjects and Method Retrospective chart review was performed for 146 patients with SSNHL. The patients were divided into 2 groups according to the method of treatment (SS and ITS simultaneously vs. SS alone). The inclusion criteria were starting treatment within 7 days after onset, and follow up pure tone audiometry at least 4 weeks after treatment. Hearing gain for pure tone threshold of each frequency and average of 4 frequencies (500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz) were compared between both groups.Results The improvement in PTA at 1-month follow-up was 27.3±20.0 dB HL in the simultaneous group and 19.1±19.5 dB HL in the SS alone group; this was not statistically significant. Complete or partial recovery at 1-month follow-up was observed in 65.3% of the simultaneous group and 69.6% of the SS alone group; this was also not significant.Conclusion There was no significant difference in hearing outcomes between the simultaneous and SS alone group. The simultaneous therapy does not appear to be superior to the SS alone therapy. Further studies using more population and longer follow-up periods are necessary.Keywords
