Electrically evoked auditory brainstem responses (EABR) were recorded in 31 postlingually deafened adults, who had recently received cochlear implants (mini-system, Gochlear Ltd). The wave consisted of three distinctpositive peaks labeled P1, P2 and P3 with latency of 1.35 (±0.14), 2.17 (±0.18) and 4.08 (±0.31) ms, respectively.The P3 threshold (EABR-T) and slope (EABR-S) were 0.9 (±0.47) mA and 0.6 (±0.28)μv/mA, respectively. Therelationships between the EABR parameters (EABR-T and -S of the P3 wave) and age, duration of deafness, promontory test and subjective respanse (T-and C-level) were investigated. The scattergram showed a strongnegative linear relationship between EABR-S and subjective T-level. This finding suggests that EABR-S is goodmeasure of postoperative perception.
