This study aimed to investigate intraoperative and long-term impedance changes in cochlear implant recipients and to evaluate the prevalence and course of electrode circuit malfunctions.
Audiologists and CI teams should monitor electrode impedance longitudinally; this study provides reference data on malfunction prevalence and trajectory that can inform troubleshooting protocols and patient counselling.
Electrode circuit malfunctions are a leading cause of cochlear implant revision surgery, and better characterisation of impedance patterns could improve long-term device management and outcomes.
- 01Study tracks intraoperative and long-term electrode impedance changes in cochlear implant recipients.
