Official title

Multi-Center Assessment of Electrode Placement and Audiologic Outcomes in Cochlear Implantation With the Advanced Bionics HiFocus L23 Electrode

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this study is to measure patient performance after cochlear implantation with the Food and Drug Administration (FDA) approved Advanced Bionics HiFocus L23 device. The specific aims of the project are as follows: 1. To measure implant audiologic performance as defined by speech performance in standard cochlear implant speech test batteries. 2. To determine scalar location after insertion through either intraoperative or postoperative imaging and correlate this with audiologic outcomes. 3. To assess the rates of preservation of residual acoustic hearing and correlate those with scalar location as determined in specific aim 2 and audiologic performance as determined in specific aim 1. 4. To correlate speech outcomes with quality of life measures, as defined by validated questionnaires including the Tinnitus Handicap Index (THI), Speech and Spatial Qualities (SSQ) Questionnaire, and Nijmegen Questionnaire. 5. To evaluate intraoperative ease of insertion from the surgeon's perspective and correlate this with postoperative electrode location and audiologic performance.
