ABSTRACT
BACKGROUND AND OBJECTIVES:
Sudden hearing loss remain a controversial issue with respect to its prognostic indicators. In a recent study, the change in distortion product otoacoustic emission (DPOAE) has been shown to provide useful information about its prognosis. The purpose of this study is to evaluate the relationship between the changes of DPOAE and hearing improvement in sudden deafness patients. SUBJECTS ANDMETHOD:
Sixty-one patients underwent pure tone audiometry (PTA) and DPOAE on their first hospital day; among them 35 patients underwent DPOAE after 2 weeks. These patients were divided into mild ( or =71 dB) group according to their initial hearing thresholds.RESULTS:
Of the 22 patients in the moderate to severe group, 11 patients showed a DPOAE response and 5 patients (45%) showed hearing improved. In 11 non-DPOAE response patients, 4 patients (36.4%) had improved. We compared PTA and OAE sum gap results by analyzing 35 patient's initial thresholds with those measured 2 weeks after the therapy. The correlation coefficient between the two group was 0.547 (p<0.05).CONCLUSION:
The results show that OAE sum is an efficient and non-invasive objective method and that it can be used to monitor the effects of treatment in sudden hearing loss patients.
