ABSTRACT
Nowadays, there is a large cohort of patients – users of cochlear implant (CI) systems, which, for a number of reasons, cannot provide reliable behavioral feedback to determine the minimum and maximum levels of electrical stimulation. There is a need to create a methodology to provide objective verification of adequacy of the setting of minimum and maximum levels of electrical stimulation in CI users (including the occurrence of stimulus artifact, which is the result of electrical stimulation pulses). One of the possible alternatives of objective determination of electrical stimulation levels at high stimulation rate is the technique of registration of electrically induced auditory steady-state responses (ASSR) to acoustic stimulation. The classical test of recording of the induced auditory brain response to constant modulated tones is the ASSR test, i.e. the registration of auditory steady-state responses, it is used to objectively determine the frequency-specific threshold values of hearing in young children, as well as a model for the study of temporary speech processing. Therefore, the revealing of the relationship between the behavioral thresholds (tonal audiometry in a free acoustic field) and the thresholds of recording of ASSR to acoustic stimulation in patients-CI users can serve as a starting point in the creation of a method for assessment of minimum and maximum electrical stimulation levels of in patients – users of cochlear implant systems. Objective: to determine the correlation between ASSR and behavioral thresholds in CI-using patients. Design: The authors have compared free acoustic fields behavioral thresholds with ASSR results in 22 CI users. Conclusion: Based on the comparison of the data obtained, the authors established close correlation relationship at the studied frequencies of 500–1000–2000–4000 Hz, which suggests the prospectivity of the further research.
