虽然耳蜗植入电极阵列的物理特性在制造商之间有很大差异，但许多耳鼻喉科医生都采用了类似的手术耳蜗造口术技术。本研究的目的是比较使用两种不同尺寸的耳蜗造口时MED-EL Flex电极的插入动力学。准备6个颞骨，采用小开窗（直径1.0 mm）或大开窗（直径1.8 mm）耳蜗造口术，并在视频透视下插入电极。分析所得视频图像的插入深度以及插入过程中电极的动态屈曲。该研究表明，小窗耳蜗造口具有“台球杆”或“台球杆”效应，稳定电极电缆并导致更容易和更深的插入。这是通过将电极的屈曲限制在耳蜗造口术部位内来实现的。
AbstractAlthough the physical characteristics of cochlear implant electrode arrays vary substantially among manufacturers, many otolaryngologists have adopted a surgical cochleostomy technique that is similar for all of them. The objective of this study was to compare the insertion dynamics of the MED-EL Flex electrode using two different sized cochleostomies. Six temporal bones were prepared with either a small fenestra (∼1.0 mm) or a large fenestra (∼1.8 mm) cochleostomy and the electrodes inserted under video fluoroscopy. The resulting video images were analysed for depth of insertion as well as dynamic flexion of the electrode during insertion. The study demonstrated that smallfenestra cochleostomies have a 'pool cue' or 'billiard cue' effect, stabilizing the electrode cable and resulting in easier and deeper insertions. This is achieved by limiting the buckling of the electrode just inside the cochleostomy site.
