A Comparison of the Results Measured by Audotory Steady State Responses and Using Frrequency-Spesific Evoked Auditory Brainstem Response

Objective: In this study, we compared the results of Auditory Brainstem Responses (tone-burst and klik ABR) and Auditory Aware Static State Responses (ASSR) in patients with sensorineural hearing loss at advanced and very advanced. Material and Methods: A total of 60 ears of a 30-patient group with sensorineural hearing loss between 2 months and 53 years of age were included in the study. Patient's tympanogram and acoustic reflex measurement, otoacoustic emission, tone-burst ABR and ASSR tests were performed. Results: There was a good correlation between tone-burst ABR and ASSR thresholds. Spearman's correlation coefficients were found 500; 1000; 2000 and 4000 Hz,; 0.612 ,0.563; 0.564 and 0.548 respectively (p <0.01). Conclusion: ASSR is a measurement method which can produce a frequency specific measurement, which gives better results at high frequencies, produces a pure sound audiogram curve shows hearing level and it is an objective measurement method which give results in a very short time. Additionaly, we recommended use combination of all tests such as tone-burst ABR and ASSR
