Our objective was to prospectively evaluate implementation of a new cochlear implant (CI) mapping technique, image-guided cochlear implant programming (IGCIP), at a site distant to the site of development. IGCIP consists of identifying the geometric relationship between CI electrodes and the modiolus and deactivating electrodes that interfere with neighboring electrodes. IGCIP maps for 17 ears of 15 adult CI patients were developed at a central image-processing center, Vanderbilt, and implemented at a distant tertiary care center, House Ear Institute. Before IGCIP and again 4 weeks after, qualitative and quantitative measures were made. While there were no statistically significant groupwise differences detected between baseline and IGCIP qualitative or quantitative measures, 11 of the 17 (64.7%) elected to keep the IGCIP map. Computed tomography (CT) image quality appears to be crucial for successful IGCIP, with 100% of those with high-resolution CT scans keeping their maps compared to 53.8% without.
我们的目标是在远离研发地点的一处机构前瞻性评估一种新的人工耳蜗（CI）图谱技术——影像引导人工耳蜗编程（IGCIP）。IGCIP包括确定CI电极与蜗轴之间的几何关系，并使干扰相邻电极的电极失活。15名成年CI患者的17只耳朵的IGCIP图谱在位于中心的图像处理中心范德比尔特制作，并在较远的三级护理中心豪斯耳科研究所实施。在IGCIP之前以及之后4周再次进行定性和定量测量。虽然在基线与IGCIP定性或定量测量之间未检测到统计学上显著的组间差异，但17名患者中有11名（64.7%）选择保留IGCIP图谱。计算机断层扫描（CT）图像质量对于成功实施IGCIP似乎至关重要，高分辨率CT扫描患者中100%保留了他们的图谱，而未进行高分辨率CT扫描的患者中这一比例为53.8%。
