Abstract:
BACKGROUND AND OBJECTIVES: The aim of this study is to assess the correlation between the threshold of click-evoked auditory brainstem response (ABR) and the pure-tone averages in various formulas. SUBJECTS AND METHOD: Data were obtained from 207 patients (326 ears) with sudden sensorineural hearing loss. All subjects underwent hearing threshold evaluation using pure tone audiogram (PTA), speech audiogram and click-evoked ABR. Linear regression analyses were applied to assess the relation between threshold of click-evoked ABR and threshold of separate frequencies of the PTA and to analyze the correlation between threshold for click-evoked ABR and various pure-tone averages. RESULTS: Results revealed a significant relation between the threshold of click-evoked ABR and PTA thresholds at 0.5 kHz, 1 kHz, 2 kHz, 3 kHz, and 4 kHz. The highest coefficients of regression and determination were 1.026 for 4 kHz and R2=0.663 for 3 kHz, respectively. The coefficient of regression was highest (=0.995) for the mean of PTA thresholds for 3 kHz and 4 kHz. The coefficient of determination was highest for the mean of PTA thresholds for 1, 2, 3 and 4 kHz (R2=0.732). Multiple regression analysis showed a significant relation between the ABR threshold and PTA thresholds for 1, 3, and 4 kHz (R2=0.732), with highest correlation coefficient at 3 kHz [ABR=11.79+(0.17x1 kHz)+(0.26x3 kHz)+(0.23x4 kHz), (p<0.05)]. CONCLUSION: The threshold of click-evoked ABR correlates best with the mean of PTA thresholds for 1, 2, 3 and 4 kHz. The PTA threshold for 3 kHz has highest correlation with the ABR threshold.
