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

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.
