OBJECTIVES: Extracochlear electrodes (EEs), defined as electrode contacts located outside the cochlea, can degrade cochlear implant (CI) performance. We present and validate an Electric Field Imaging (EFI)-based algorithm that helps detect EEs and can be used intra- or post-operatively.

EFI-based automatic detection of extracochlear electrodes is a clinically promising tool that could be integrated into post-implantation programming sessions to identify electrode misplacement without additional imaging; adoption should await broader clinical validation and device-manufacturer integration.
Reliable, non-radiological detection of extracochlear electrode contacts could meaningfully improve cochlear implant programming outcomes and reduce unnecessary radiation exposure from follow-up imaging.
- 01EFI-based algorithm automatically detects electrodes sitting outside the cochlea in CI recipients.
- 02Validated in both bench (lab) and clinical settings, strengthening confidence in real-world applicability.
- 03Method does not require additional imaging, potentially reducing radiation exposure and cost.
- 04Extracochlear electrodes can degrade CI performance; early detection is clinically important.
- 05Further large-scale multicentre validation is needed before routine clinical adoption.
Electric Field Imaging can automatically and accurately detect extracochlear electrode contacts in cochlear implants.
