摘要背景：圆窗植入法和耳蜗造口术是人工耳蜗植入术中最常用的两种方法，但对于哪种方法最佳仍存在争议。由于缺乏视觉观察方法，很难比较它们之间的电极位置。目的：评价和比较RWI和耳蜗造口入路治疗婴幼儿CI的电极位置。材料与方法：回顾性分析了2016年1月至2017年7月在我院接受CI和颞部锥形束计算机断层扫描（CBCT）术后扫描的24例患者（16例男性，8例女性）。手术记录和图像用于确定手术技术。以圆窗显露为主，15例行RWI，11例行耳蜗造口术。结果：平均年龄2.4（范围0.8-7）岁。CBCT图像显示所有电极阵列均位于鼓阶内。电极触点与蜗轴的距离（EMI）、耳蜗内插入长度和电极阵列在耳蜗插入处的角度差异均无统计学意义。结论及意义：两种入路均能满意地将电极置入鼓阶。由于CBCT可以清晰地显示电极和耳蜗结构，因此可以可靠地评估电极位置。
Abstract Background: As the two most commonly used approaches for cochlear implants (CIs), the round-window insertion (RWI) and cochleostomy are still controversial about which approach is optimal. The lack of visual observation methods makes it difficult to compare the electrode position between them. Objectives: To evaluate and compare the electrode position between RWI and cochleostomy approaches for CI among young children. Materials and methods: Twenty-four patients (16 male, 8 female) accepting CI and temporal cone-beam computed tomography (CBCT) scan post-operation in our hospital from January 2016 to July 2017 were analyzed retrospectively. Operative notes and images were used to identify the surgical technique. Mainly depending on the round-window exposure, 15 cochleae were performed with RWI and 11 performed with cochleostomy. Results: Mean age, 2.4 (range 0.8–7) years. The CBCT images showed that all the electrode arrays were located in scala tympani. There were no significantly statistical differences in the distance between electrode contacts and modiolus (EMI), intracochlear insertion length and the angle of electrode arrays at the insertion site of the cochlea. Conclusions and significance: Both approaches could insert electrodes into scala tympani satisfactorily. As electrodes and cochlear structures could be clearly visualized, CBCT can be applied to assess the electrode position reliably.
