Abstract
Background and Objectives Acute low-tone sensorineural hearing loss refers to a condition wherein thresholds increase only at low frequencies in pure-tone audiometry. Systemic steroid treatment is commonly used for acute low-tone sensorineural hearing loss without vertigo, but there has been no established treatment in most clinical researches. The purpose of this study is to compare and analyze the short-term effects of high- and half-dose oral steroid therapy on patients suffering from acute low-tone sensorineural hearing loss without vertigo. Subjects and Method Forty-six patients diagnosed with acute low-tone sensorineural hearing loss were divided into two groups and treated with high-dose (24 patients) and half-dose (22 patients) steroids, respectively. A retrospective analysis was conducted on their medical records. Results There were no significant differences between the two groups in any of the following: age, sex ratio, duration of symptoms before treatment, pure-tone hearing thresholds, low frequency hearing thresholds and speech intelligibility. However, both groups showed significant differences in hearing thresholds before and after treatment. In addition, no significant difference was noted in the recovery and recurrence rate between the two groups. Conclusion According to the results of this study, there is no difference in treatment effect between the high- and half-dose groups. Therefore, half-dose steroids may be used as a treatment option for acute low tone sensorineural hearing loss. Key words: Low-tone ã Sensorineural hearing loss ã Steroid
