چکیده
Background: There is evidence that the cochlear volume may influence audiometric thresholds and CI electrodes’ impedance. The aim of present study was to evaluate impedance changes over time correlate them residual cochlea. Methods: An MRI scan performed via 3-D reconstruction before every surgery obtain a for each ear. We repeated assessments electrode impedance, both intra-operatively post-implant, at following intervals: 3 months, 6 one year. same type perimodiolar array implanted each. Results: Thirty-four patients (10 (29.41%) male 24 (70.59%) female patients) were evaluated. Patients received implants between 2008 2017. mean age implantation 13 ± 17.17 years, average hearing improved after year surgery. volumes ears 68.16 10.74 mm3 (right ear) 56.54 13.75 (left ear). observed an increase in basal 3rd month. Yet, apical there decrease averaged values. Conclusions: Post-operative measurements increased when compared intraoperatively measured Newly formed connective tissue thought be cause higher
