背景:导致尖端折叠的机制之一是电极阵列的卷绕方向与耳蜗的弯曲方向之间的不对准。目的:我们回顾了2010年1月至2021年12月接受人工耳蜗植入手术的患者的手术视频和计算机断层扫描(CT)数据集,特别注意外科医生显微镜下耳蜗的方向。方法:分析CT数据集和视频记录以测量“倾斜角”,即耳蜗卷绕平面与水平面之间的角度。结果:有220例符合标准并完成了分析。平均倾角为12.1±9.5,最小值为-9.4,最大值为44.6。然而,每个外科医生都有一个有利的倾斜角度range.Conclusion:了解的倾斜角度,并努力减少电极插入过程中的不对准的机会,可能有助于防止尖端折叠的超薄perimodiolar电极阵列。
Background:One of the mechanisms that cause tip fold-over is a misalignment between the electrode array’s coiling direction and the cochlea’s curving direction.Objectives:We reviewed surgical videos and computed tomography (CT) datasets of the patients who underwent cochlear implantation procedures from January 2010 to December 2021, paying particular attention to the cochlea’s orientation in the surgeon’s microscopic view.Methods:CT dataset and video recordings were analyzed to measure the “slope angle,” which is the angle between the cochlea’s coiling plane and the horizontal plane.Results:There were 220 cases that met the criteria and completed the analysis. The mean slope angle was 12.1±9.5, with a minimum of− 9.4 and maximum of 44.6. However, each surgeon had a favored slope angle range.Conclusion:Understanding the slope angle and making an effort to reduce the chance of misalignment during electrode insertion may help prevent tip fold-over of slim perimodiolar electrode arrays.
