Electrode migration and magnet dislocation are uncommon but clinically relevant complications following cochlear implant (CI) surgery. Most previously published studies are limited by small sample sizes, restricting the ability to precisely estimate incidence rates and risk factors....
Cochlear implant teams should review these single-center complication benchmarks — particularly electrode migration and magnet dislocation rates — against their own outcomes, but practice changes should await multi-center validation.
Reliable, large-scale complication data for cochlear implants are scarce; this cohort study adds important benchmarking information that can inform surgical consent, device selection, and post-operative monitoring protocols.
- 01Large single-center cohort study reporting complication rates after cochlear implant surgery.
- 02Electrode migration (movement of the implanted wire inside the cochlea) was a key outcome measure.
- 03Magnet dislocation rates within the implant were also reported.
- 04Single-center design limits generalisability across different surgical teams and device brands.
- 05Directly relevant to cochlear implant audiologists, surgeons, and device manufacturers.
Electrode migration is a quantifiable and reportable complication in cochlear implant recipients.
