Abstract: Objective To develop electrically evoked auditory brainstem response(EABR) modules of REZ-Ⅰ domestic cochlear implant device,and testify the reliability and validity of the modules.Methods Postoperative EABR were recorded in guinea pigs by using the self-designed EABR module.Results EABR 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 e Ⅲ 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 e Ⅲ 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.Conclusion According 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.
