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.
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.
The NRT value of straight electrode fell in the range of 160 microV to 170 microV and contour electrode 150 microV to 160 microV. The NRT were going up higher a little bit from electrode twenty to electrode one.
The contour electrode requires less power consumption than straight electrode in Nucleus 24 cochlear implant system.
通过比较24通道人工耳蜗系统中直电极与弯电极的神经反应遥测（NRT）值，了解螺旋神经节细胞对电刺激的神经反应。
46例接受24通道人工耳蜗植入的患者被分为两组，每组23例，分别植入弯电极和直电极。对每组的NRT值进行测试和比较。
直电极的NRT值在160微伏至170微伏范围内，弯电极的NRT值在150微伏至160微伏范围内。从电极20到电极1，NRT值略有升高。
在24通道人工耳蜗系统中，弯电极比直电极功耗更低。
