INTRODUCTION: The aim was to establish the reliability measurement of Evoked Compound Action Potential (ECAP) thresholds obtained through the conventional AutoNRT programming system and CR220 intraoperative remote assistant. Another area of interest is to compare the intraoperative NRT thresholds with the post operative ones.
METHODS: Nineteen patients who received a Nucleus CI24RE or CI422 cochlear implant for severe to profound hearing loss were included in the study. The patients’ ages ranged from 13 months to 15 years (mean is 4). Intraoperative NRT thresholds were measured on all operational electrodes using both the conventional AutoNRT programming system and the CR220 intraoperative remote assistant.
RESULTS: NRT thresholds revealed no statistically significant differences between the traditional and remote conditions for all electrodes tested and also when the NRT thresholds were compared on electrode basis. Intraoperative NRT thresholds were also compared with the postoperative AutoNRT thresholds. The intraoperative NRT thresholds obtained with the two measurement systems were found significantly higher than the postoperative NRT thresholds.
DISCUSSION AND CONCLUSION: CR220 intraoperative remote assistant provides reliable NRT thresholds. There were no statistically significant difference between NRT thresholds obtained through CR220 and those obtained with the conventional AutoNRT method.
