Real-Time Intracochlear Distance Sensing and Navigation Using a Dual Fiber Optical Coherence Tomography System

HYPOTHESIS: A dual fiber-based optical coherence tomography (OCT) system can be used for real-time intracochlear navigation and distance computation in the human cochlea. BACKGROUND: OCT is a contrast- and radiation-free modality that provides real-time 2- and 3-dimensional imaging of tissue microanatomy at higher resolutions than those of conventional MRI or CT....

✦ Clinical Takeaway ✦

This technology is not yet ready for routine clinical use, but its demonstrated feasibility in the human cochlea marks a meaningful step toward real-time surgical navigation for cochlear implant insertion.

✦ Why It Matters ✦

Real-time intracochlear sensing during CI insertion could reduce electrode trauma and improve hearing preservation outcomes, representing a potential step change in implant surgical precision.

✦ Key Points ✦

01A dual fiber optical coherence tomography (OCT) system demonstrated real-time distance sensing inside the human cochlea.
02The system enables intraoperative navigation during cochlear implant electrode insertion.
03OCT-based sensing targets the reduction of intracochlear trauma by providing live spatial feedback.
04Study conducted in the human cochlea, strengthening translational relevance over animal-only studies.
05Published in Otology & Neurotology; relevant to CI surgeons, engineers, and hearing-preservation researchers.
