CT Guided CI Programming

NCT04506424 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 19

No results posted yet for this study

Summary

The current standard of care for cochlear implants (CI) does not address the significant pitch-place mismatch that is inherent in cochlear implantation (see detailed description below). The present study uses postoperative Flat Panel (higher resolution than standard) CT imaging to measure where CI electrodes sit within an individual's cochlea; doing so allows for more accurate frequency mapping (and thus pitch perception). The hypothesis of this study is that long-term (1 year) use of CT image-based frequency maps, beginning on the first day of CI activation, will improve user performance in the areas of speech and music perception, as compared to the use of default programming settings.

CT Guided Cochlear Implant Programming

Flat Panel (high resolution) CT scans of the temporal bones, including the inner ears, will be obtained. The research team will use the scans to generate custom cochlear implant (CI) programs for use by the participants.
