Objective: In the present study, thresholds of airway tone-burst auditory brainstem response (ABR), and pure-tone audiometry were compared, and correlations between threshold values obtained with classical audiometric methods, and pure-tone airway hearing in individuals with advanced, and very advanced sensorineural (S/N) hearing loss were investigated. Methods: Eighty patients with advanced and very advanced S/N hearing loss were included in the study. Pure-tone air conduction thresholds of advanced, and very advanced S/N hearing loss patients detected at 500, 2000 and 4000 Hz frequencies were compared with tone-burst ABR threshold values. Results: Our study population consisted of males with a mean age of 21.8±3.45. Mean differences between thresholds of tone-burst, and pure-tone audiometry were detected to be 4.75 dB, 6.25 dB, and 4.87 dB at stimulus frequencies of 500 Hz, 2000 Hz, and 4000 Hz, respectively. Conclusion: In conclusion, in patients with S/N hearing loss, a strong correlation is found between pure-tone audiometry thresholds, and electrophysiological thresholds obtained at 500, 2000, and 4000 Hz with tone-evoked ABR wave-V. Tone-ABR can be used as a reliable test in the diagnosis of patients with hearing loss in conditions where pure-audiometry cannot be performed.
