이명 재훈련 치료의 예후인자 분석

Backgrounds and Objectives: Tinnitus is a subjective symptom and there are no objective tests for the diagnosis of subjective tinnitus. The purpose of this study is to find out the objective tests as a prognostic factor to predict the effect of tinnitus retraining therapy and to assess whether the correlation between distortion product otoacous- tic emissions and pure tone audiometry could be a prognostic factor in tinnitus retraining therapy. Materials and Methods: One hundred and seventy nine patients treated with tinnitus retraining therapy from September 2009 to April 2012 were investigated. The scores of tinnitus handicap inventory questionnaire before and after tinnitus retraining therapy were used to determine whether tinnitus was improved after tinnitus retraining therapy. Result of tinnitus retraining therapy was analyzed according to the clinical characteristics, demographic factors, and correlation between distortion product otoacoustic emissions and pure tone audiometry. Results: Overall success rate of the treatment was 60.3%. There was a significant correlation between success rate of treatment and correlation between distortion product otoacoustic emissions and pure tone audiometry. Conclusions: The tests of distortion product otoacoustic emissions and pure tone audiometry in combination could be a good test to predict the result of tinnitus retraining therapy.
