耳内镜下经耳道下入路人工耳蜗植入术的解剖研究
发布时间：2018-08-18 21:30
【摘要】：目的介绍一种新的耳内镜下经耳道下入路人工耳蜗植入手术方式,探讨各种植入方式的优缺点。方法在3例甲醛固定的成人正常颞骨标本开展新手术方式,并测量相关参数。结果所有标本均在耳内镜下显露圆窗龛,并植入电极,未开放乳突气房和损伤鼓索神经、面神经。圆窗膜外侧缘到鼓索神经出骨性鼓环处距离(a)5.47±0.11mm;圆窗下缘到外耳道下壁6点电极骨槽骨性鼓环端距离(b)5.62±0.43mm;外耳道下壁长度(c)12.63±0.99mm;面神经乳突段到外耳道下壁电极骨槽的最短距离(d)4.65±0.50mm;外耳道上壁长度(e)17.02±1.52mm。结论耳内镜下经耳道下入路人工耳蜗植入术是一种微创、安全、快捷且容易学习的具有可行性的新手术方式,对显微镜下圆窗显露不满意等复杂病例更具有其优势,但其具体效果尚待临床上进一步验证,并且对于其存在的局限性和并发症风险等问题仍需进一步的研究改进。
[Abstract]:Objective to introduce a new endoscopic approach for cochlear implantation. Methods A new operative method was performed in 3 normal adult temporal bone specimens fixed with formaldehyde and the related parameters were measured. Results all specimens were exposed by endoscope and implanted with electrodes. The papillary chamber was not opened and the nerve of tympanic cord and facial nerve was injured. (a) 5.47 卤0.11mm from the lateral edge of the round window membrane to the osseous ring of the chorda tympani nerve, (b) 5.62 卤0.43mm from the lower edge of the round window to the inferior wall of the external auditory canal, (c) 12.63 卤0.99mm from the length of the inferior wall of the external auditory meatus, and the most important distance from the mastoid segment of the facial nerve to the electrode bone groove of the inferior wall of the external auditory canal. The short distance (d) was 4.65 卤0.50mm, the length of the superior wall of the external auditory canal was 17.02 卤1.52mm. Conclusion Endoscopic transauricular cochlear implantation is a new operative method with minimally invasive, safe, fast and easy to learn. It is more advantageous to complicated cases, such as dissatisfactory exposure of round window under microscope. However, its specific effect needs to be further verified in clinic, and further research and improvement are needed for its limitation and complication risk.
