Electrode array migration is a rare condition after cochlear implantation that can impair auditory outcomes but often remains undetected during routine follow-up. We evaluated the clinical utility of an electrical impedance-based, machine learning method for detecting postoperative electrode array migration using routinely acquired telemetry data....

If validated in larger prospective cohorts, this method could replace radiation-based imaging for routine electrode migration surveillance; clinicians should watch for peer-reviewed validation before adopting it.
A radiation-free, automated migration-detection tool could meaningfully reduce patient radiation exposure and imaging costs while enabling earlier detection of electrode displacement in CI recipients.
- 01Electrode array migration after cochlear implantation can degrade hearing outcomes if undetected.
- 02The method relies solely on impedance telemetry data already collected in standard CI follow-up — no additional imaging required.
- 03Automation reduces reliance on clinician interpretation of electrical patterns.
- 04Radiation-free approach is especially relevant for pediatric CI populations.
- 05Study represents an early evaluation; large-scale prospective validation is still needed.
Routine impedance telemetry can be used to automatically detect cochlear implant electrode array migration without radiation.
