Received May 31, 2017 Revised August 4, 2017 Accepted August 23, 2017 Address for correspondence Jong Dae Lee, MD, PhD Department of OtolaryngologyHead and Neck Surgery, Soonchunhyang University College of Medicine, Bucheon Hospital, 170 Jomaru-ro, Bucheon 14584, Korea Tel +82-32-621-5054 Fax +82-32-621-5018 E-mail ljdent@schmc.ac.kr Background and ObjectivesZZAcute 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 highand half-dose oral steroid therapy on patients suffering from acute low-tone sensorineural hearing loss without vertigo. Subjects and MethodZZForty-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. ResultsZZThere 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. ConclusionZZAccording to the results of this study, there is no difference in treatment effect between the highand half-dose groups. Therefore, half-dose steroids may be used as a treatment option for acute low tone sensorineural hearing loss. Korean J Otorhinolaryngol-Head Neck Surg 2018;61(4):177-81
