摘要
目的通过对人工耳蜗植入手术相关的解剖结构进行观察、测量,为人工耳蜗植入手术提供理论参考。方法对10个尸头20侧颞骨标本进行解剖,模拟人工耳蜗植入术,在手术显微镜下观察、测量与人工耳蜗植入手术相关的解剖数据。结果镫骨头下缘与耳蜗底回切开点之间的距离为2.154±0.173mm,镫骨头下缘与圆窗龛之间的距离为2.470±0.582mm,圆窗龛与耳蜗底回切开点的距离为1.422±0.369mm,镫骨头下缘与耳蜗第二回切开点之间的距离为3.238±0.151mm,镫骨头下缘与匙突之间的距离为2.831±0.269mm,匙突与耳蜗第二回切开点之间的距离为1.338±0.132mm,面神经垂直段与圆窗龛的距离为4.830±1.152mm,面神经与鼓索神经在圆窗平面的距离为2.480±0.274mm,卵圆窗与圆窗的距离为1.820±0.452mm,耳蜗底回前缘与颈内动脉管的距离为1.856±0.372mm。结论人工耳蜗植入手术中切开耳蜗底回的位置位于圆窗龛前方约1.422mm,镫骨头下缘约2.154mm处;耳蜗第二回切开点位于匙突下约1.338mm处;卵圆窗与圆窗、面神经与鼓素神经间的平均距离的测量为术中寻找圆窗龛、避免损伤面神经等重要结构提供了参考。
Objective To investigate the related parameters of temporal bone structure in the surgery of cochlear implantation. Methods Inasurgical simulation expedment, twenty human temporal bones were studied and measured to determine the correlation parameters. Results The position of cochlear inserting the electrode array into the cochlear base turn was 2.154 ± 0.173 mm underneath stapes. Distance between stapes and round window was 2.470 ± 0.582 mm. The location of cochlear inserting the electrode array into the cochlear base turn was 1.422 ± 0.369 mm anterion to round window. The position of cochlear inserting the electrode array into the second cochlear turn was 3. 238 ± 0. 151 mm underneath stapes. Distance between stapes and cochleariform process was 2. 831 ± 0.269 mm. The location of cochlear inserting the electrode array into the second cochlear turn was 1. 338 ± 0. 132 mm inferior to cochleariform process. Distance between vertical segment of facial nerve and round window was 4. 830 ± 1. 152 mm. Distance between facial nerve and chorda tympani nerve at level of round window was 2.480 ± 0. 274 mm. Distance between oval window and round window was 1. 820 ± 0.452 mm. The cochlear base turn was 1. 856 ± 0.372 mm anterion to carotis interna artery canal. Conclusion These parameters provide a reference value to determine the position of cochlear inserting the electrode array into the scale tympani to prevent potential damage to facial nerve in surgery.
