To investigate the related parameters of the temporal bone structure for determining the position of implanting electrode into the scala tympani in cochlear implantation surgery through the facial recess and epitympanum approach.
In a surgical simulation experiment, 20 human temporal bones were studied and measured to determine the related parameters of the temporal bone structure.
The distance 5.91∓0.29 mm between the short process of the incus and the round window niche, 2.11∓0.18 mm between the stapes and the round window niche, 6.70∓0.19 mm between the facial nerve in the perpendicular paragraph and the round window niche, 2.22∓0.21 mm from the pyramidal eminence to the round window, and 2.16∓0.14 mm between the stapes and the round window. The minimal distance between the implanting electrode and the vestibular window was 2.12∓0.19 mm. The distance between the cochleariform process and the round window niche was 3.79∓0.17 mm. The position of the cochlear electrode array insertion into the second cochlear turn was 2.25∓0.13 mm under the stapes. The location of the cochlear electrode array insertion into the second cochlear turn was 2.28∓0.20 mm inferior to the pyramidal eminence.
These parameters provide a reference value to determine the different positions of cochlear electrode array insertion into the scale tympani in different patients.
研究颞骨结构的相关参数，以确定在人工耳蜗植入手术中经面神经隐窝和上鼓室入路将电极植入鼓阶的位置。
在一项手术模拟实验中，对20例人类颞骨进行研究和测量，以确定颞骨结构的相关参数。
砧骨短突与圆窗龛之间的距离为5.91±0.29mm，镫骨与圆窗龛之间的距离为2.11±0.18mm，垂直段面神经与圆窗龛之间的距离为6.70±0.19mm，锥隆起至圆窗的距离为2.22±0.21mm，镫骨与圆窗之间的距离为2.16±0.14mm。植入电极与前庭窗之间的最小距离为2.12±0.19mm。蜗形突与圆窗龛之间的距离为3.79±0.17mm。耳蜗电极阵列插入第二蜗旋的位置在镫骨下方2.25±0.13mm处。耳蜗电极阵列插入第二蜗旋的位置在锥隆起下方2.28±0.20mm处。
这些参数为确定不同患者耳蜗电极阵列插入鼓阶的不同位置提供了参考值。
