To determine the relationship between the electrically evoked nerve action potential (Neural Response Telemetry [NRT]) and behavioral levels (T- and C-level) for pediatric patients using the Nucleus 24 cochlear implant system.
A hospital based study of pediatric cochlear implant patients in the period between June 2000 and December 2008. At King Abdul-Aziz University Hospital (KAUH) Saudi Arabia the Neural Response Telemetry was administered to 47 children (mean age at implantation: 4 years) with the Nucleus 24 cochlear implants. Four intra cochlear electrodes (numbers 5, 10, 15, and 20) were tested one-month post-implantation, the neural response threshold compared with the behavioral threshold and the maximum comfort level estimated at the same time.
At all the electrode numbers, the mean for NRT level measurements was significantly higher than that for the T-level measurements and the mean for the C-level measurements was significantly higher than that for NRT level measurements The correlation analyses showed positive correlation between C-level and NRT level measurements and T-level and NRT level measurements.
There was a positive correlation between NRT value measurements and both T and C value measurements. Therefore, it is useful to use the NRT values to predict the behavioral T and C values in prelingual children.
确定使用Nucleus 24型人工耳蜗系统的儿科患者的电诱发神经动作电位（神经反应遥测术[NRT]）与行为水平（T级和C级）之间的关系。
一项基于医院的对2000年6月至2008年12月期间儿科人工耳蜗植入患者的研究。在沙特阿拉伯阿卜杜勒-阿齐兹国王大学医院（KAUH），对47名植入Nucleus 24型人工耳蜗的儿童（植入时平均年龄：4岁）进行了神经反应遥测术。在植入后一个月测试了四个耳蜗内电极（第5、10、15和20号），将神经反应阈值与行为阈值进行比较，并同时估计最大舒适水平。
在所有电极编号中，NRT水平测量的平均值显著高于T级测量的平均值，C级测量的平均值显著高于NRT水平测量的平均值。相关性分析显示C级与NRT水平测量之间以及T级与NRT水平测量之间呈正相关。
NRT值测量与T值和C值测量均呈正相关。因此，使用NRT值来预测语前儿童的行为T值和C值是有用的。
