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 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.
CONCLUSION:The contour electrode requires less power consumption than straight electrode in Nucleus 24 cochlear implant system.
