摘要
目的 探讨人工耳蜗植入术中神经反应遥测 (neuralresponsetelemetry,NRT)技术的应用情况。方法 对 10例NucleusCI2 4M及 4例NucleusCI2 4R(CS)人工耳蜗植入术的患儿在术中及术后一个月进行NRT检测 ,比较两者术中和术后的电诱发复合动作电位 (electrically -evokedcompoundactionpotential ,ECAP)阈值差异 ,并利用术中ECAP阈值指导首个言语处理器映射图。结果 14例患儿术中各电极的ECAP平均阈值均高于术后一个月开机时相应电极的ECAP平均阈值 ,CI2 4M植入体各电极的术中ECAP阈值比术后相应电极的ECAP阈值平均高 11CL ;术中 10个电极相应的ECAP波形采集只需 5分钟 ;术后开机整个过程约 1小时。结论 术中应用NRT技术可快捷地了解植入体安置的情况 ,指导术后首个映射图的调试 ,明显节省了术后开机调试的时间 ,操作简单、方便 。
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.
