Electrical middle latency responses in children with cochlear implants

Forty-five prelingually deaf children who were implanted with Nucleus 24 Contour cochlear implants participated in this study. Age of the subjects at the time of cochlear implantation ranged from 2 to 9 years. For the EMLR measurements, biphasic current pulses of 25 μs/phase were used at a repetition rate of 11 pulses per second. The stimulation mode was MP 1+2. The recording window included 10 ms pre-stimulus and 90 ms post-stimulus time. The bandpass filter setting was 10 to 100 Hz and 250 recordings were averaged. The EMLRs were recorded at 3 weeks after implantation. Data from three electrodes – apical electrode (E20), intermediate electrode (E12) and basal electrode (E5) – were involved. The waveforms, thresholds, latencies and amplitudes of EMLRs were analysed. Behavioural thresholds (T-levels) and most comfortable levels (C-levels) at six months after implantation were used for comparison with the EMLR data. The latencies and amplitudes of EMLRs at threshold level were compared with MAP dynamic ranges, and EMLR thresholds were compared with behavioural measures.
