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. 50 patients were implanted with Nucleus cochlear implants (Cochlear — Australia) and other 25 patients — with Advanced Bionics implants (Switzerland).

RESULTS

The impedance dynamics analysis in two groups of patients implanted with «Cochlear» and «Advanced Bionics» cochlear implants demonstrated that statistically significant decrease in impedance (p<0.05) was observed after the beginning of electrical stimulation and the reduction of postoperative inflammatory process in the inner ear. The stabilization of the impedance levels in both groups of patients was obtained in 3—6 months after the switch-on of speech processor.
