돌발성 난청의 구제치료

Background and Objectives: The purpose of this study was to analyze the outcome of remedial treatment for patients who had been over 2 weeks after the onset of sudden onset of hearing loss and who did not recover after the initial treatment. Subjects and Methods: Retrospective chart review was done with the patients who were diagnosed as sudden sensorineural hearing loss and visited our clinic 2 weeks after onset or not improved after receiving oral steroid treatment from January 2010 to December 2015. Twenty four patients out of 187 SSNHL were enrolled. Hearing outcomes were determined by hearing gains in pure-tone average (PTA) measured by audiometry before and 3 months after salvage therapies. Results: Significant larger hearing gains in PTA were found in the oral steroid and intratympanic injection groups than the control group. Intratympanic group resulted in a significantly larger PTA improvement than the oral steroid group (p=0.035). Conclusion: Therefore, in the case of sudden hearing loss more than 2 weeks after onse or that failed in the first treatment, it is necessary to treat either oral steroid or intratympanic injection of dexamethasone considering the general condition and the environment of the patient.
