| 摘 要： | 目的:测试和比较Nucleus 24人工耳蜗系统中直电极与弯电极神经反应遥测(NRT)值的差别,分析内耳螺旋神经节细胞对不同电极电刺激反应特性的差异。方法:对46例进行耳蜗植入和编程的Nucleus 24人工耳蜗系统直电极与弯电极患者进行配对分析,计算患者vNRT值的均值,并进行统计学比较。结果:直电极的NRT值为160～170μV,弯电极为150～160μV,总的趋势是低频值较低而高频值较高。结论:Nucleus 24人工耳蜗系统弯电极较直电极所需电刺激量略低。

| Abstract: | Objective:To learn the neural response of spiral ganglion cell to electrical stimulus by comparing the neural response telemetry(NRT) value between straight electrode and contour electrode in Nucleus 24 cochlear implant system.Method:Fourty-six patients with Nucleus 24 cochlear implants were paired into two groups: 23 with contour electrode and 23 with straight electrode respectively.NRT value of each group were tested and compared.Result:The NRT value of straight electrode fell in the range of 160 μV to 170 μV and contour electrode 150 μV to 160 μV.The NRT were going up higher a little bit from electrode twenty to electrode one.Conclusion:The contour electrode requires less power consumption than straight electrode in Nucleus 24 cochlear implant system. |
