Received June 28, 2018 Revised July 23, 2019 Accepted August 7, 2019 Address for correspondence Jae Hwan Kwon, MD, PhD Department of OtolaryngologyHead and Neck Surgery, Kosin University College of Medicine, Kosin University Gospel Hospital 262 Gamcheon-ro, Seo-gu, Busan 49267, Korea Tel +82-51-990-6247 Fax +82-51-245-8539 E-mail entkwon@hanmail.net Background and Objectives Sudden sensoryneural hearing loss (SSNHL) is an otological emergency disease of a non-specific cause. If there is no improvement or if the degree of hearing loss is severe, patients are often referred to other medical institution. Many papers have reported regarding the treatment results of SSNHL, however, most of them failed to mention the fact that patients were referred from other clinics after steroid treatment. This paper would like to compare the treatment results between patient groups who had been referred following steroid treatment and those who received steroid treatment for the first time. Subjects and Method We retrospectively analyzed 127 patients from January 2015 to August 2017. Patients who received steroid treatment for the first time were classified as group 1; those who had received steroid treatment at another hospital and those who were re-treated were classified as group 2. The treatment results of each group were evaluated. Results According to the results of this study, the recovery rates for group 1 and 2 were 66.7% and 31.4%, respectively. Conclusion Most of the previous studies on the treatment results of sudden hearing loss were performed in tertiary medical institutions. It is likely that the treatment results of patients who recovered after treatment in the primary and secondary medical institutions were missed, which means that the results of steroid therapy may be better than those reported previously.
