Abstract:
OBJECTIVETo develop electrically evoked auditory brainstem response(EABR) modules of REZ-I domestic cochlear implant device, and testify the reliability and validity of the modules.
METHODSPostoperative EABR were recorded in guinea pigs by using the self-designed EABR module.
RESULTSEABR waves were recorded in all 15 ears of 9 guinea pigs with normal hearing. The threshold was (159.00 ± 50.21) current level (CL) and eIII wave latency was (2.36 ± 0.46) ms of 100 µs pulse width stimulation; for 150 µs pulse width stimulation, the threshold was (131.44 ± 49.25) CL and eIII wave latency was (2.59 ± 0.46)ms; for 200 µs pulse width stimulation, the threshold was (119.63 ± 52.56) CL and e III wave latency was (2.62 ± 0.44)ms.
CONCLUSIONAccording the preliminary results of the study, the reliability and stability of the EABR modules of domestic cochlear implant device can meet the demands of EABR recording.
