This paper describes the construction of portals for electrode placement during cochlear implantation and emphasises the utility of pre-operative temporal bone three-dimensional computed tomography.
Temporal bone three-dimensional computed tomography was used to plan portal creation for electrode insertion.
Pre-operative temporal bone three-dimensional computed tomography can be used to determine the orientation of temporal bone structures, which is important for mastoidectomy, posterior tympanotomy and cochleostomy, and when using the round window approach.
It is essential to create appropriate portals (from the mastoid cortex to the cochlea) in a step-by-step manner, to ensure the safe insertion of electrodes into the scala tympani. Pre-operative three-dimensional temporal bone computed tomography is invaluable in this respect.
本文描述了耳蜗植入术中电极放置的入路构建，并强调了术前颞骨三维计算机断层扫描的实用性。
使用颞骨三维计算机断层扫描来规划电极插入的入路创建。
术前颞骨三维计算机断层扫描可用于确定颞骨结构的方向，这对于乳突切除术、后鼓室切开术和圆窗切开术以及使用圆窗入路时非常重要。
以循序渐进的方式创建合适的入路（从乳突皮质到耳蜗）至关重要，以确保电极安全插入鼓阶。在这方面，术前颞骨三维计算机断层扫描是非常宝贵的。
