[Threshold dynamics of the auditory nerve electrically evoked compound action potential in implanted children].

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.

[Postoperative dynamics of electrode impedance changes in children with cochlear implants].

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.
