Intraoperative detection of cochlear implant electrode tip fold-over using transimpedance matrix (TIM) measurements: a comparative study with X-ray imaging

Key Points

• To evaluate the effectiveness of transimpedance matrix (TIM) measurements for intraoperative cochlear implant (CI) electrode positioning compared to X-ray imaging.
• Conducted intraoperative monitoring using TIM for CI electrodes.
• Compared TIM measurements with traditional X-ray imaging.
• Assessed accuracy and radiation exposure of both techniques.
• TIM showed superior accuracy in detecting electrode fold-over compared to X-ray.
• Use of TIM reduced the need for revision surgeries due to better intraoperative monitoring.
• No radiation exposure was associated with TIM measurements.
