Abstract:
Objective To explore the advantages of intraoperative NRT measurement(neural response telemetry)during cochlea implant surgery.Methods Intraoperative and postoperative NRT measurements were tested in ten SNHL children with CI24M-Nucleus and four SNHL children with CI24R(CS)-Nucleus, the ECAP threshold of intraoperative and postoperative measurements were compared, and the first maps were set up according to the intraoperative ECAP threshold.Results The average intraoperative ECAP threshold of 22 electrodes was higher than postoperative ECAP threshold, the average intraoperative ECAP threshold of CI24M-Nucleus' 22 electrodes was 11CL greater than postoperative ECAP threshold. It was just five minutes to record ECAP of 10 electrodes, and the beginning of fitting was finished in one hour.Conclusion It is confirmed that intraoperative NRT measurement could test the integrity of implants, and could estimate the first map. It is convenient to use and should be popularized.
