Objective: To estimate the applicability of electrically evoked auditory brainstem response (eABR) registration for the estimation of neural integrity after cochlear implantation (CI) in children with auditory neuropathy spectrum disorder (ANSD) and to compare the eABR data with patient's hearing performance.
Material And Methods: 4 children, Nucleus (Cochlear) CI users, with ANSD were enrolled in the study. Hearing performance in these children ranged from successful to unsatisfied.

Unlabelled: Currently, the number of patients with bilateral sensorineural deafness treated with cochlear implantation (CI) is increasing in the Russian Federation. In this regard, methods of assessing the auditory rehabilitation of this category of patients become more relevant.
Objective: To investigate the correlation of the speech intelligibility in quiet with frequency resolving power (FRP) of hearing using a ripple-spectrum phase reversion test (RSPRT) in CI users.
Objective: To study the dynamics of thresholds of the electrically evoked compound action potential of the auditory nerve (ECAP) during neural responce telemetry (NRT) intraoperatively, at the time of activation of the cochlear implantation system (CI) and after 3 and 6 months.
Material And Methods: The study included 50 children aged 1 year to 4 years with bilateral sensorineural deafness, operated on by Nucleus CI512 Profile + CP900 CI systems («Cochlear», Australia). In all patients, the electrode array was fully inserted.

Unlabelled: To determine the electrode impedance dynamics changes in the postoperative period after cochlear implantation as well as the time of their stabilization.
Material And Methods: 75 patients with a bilateral sensorineural deafness aged from 1 to 4 years (average age - 1.5 years) were included in the study.
