UNLABELLED
Cochlear implantation has been recommended for children under 24 months of age. The use of objective measures is needed to help speech processor programming. The electrically evoked compound potential (EAP), which can be assessed by neural response telemetry (NRT), is one of those objective measures.
AIM
to determine how often the EAP can be recorded by NRT system during surgery and to describe the responses.
STUDY DESIGN
Clinical with transversal cohort.
MATERIAL AND METHOD
The impedances and NRT were measured in a group of 17 Nucleus 24 implant users. The responses were analyzed and compared to the etiology, hearing loss duration and electrode array position.
RESULTS
The EAP was easily recorded in the apical electrodes and, in otosclerosis and meningitis cases the EAP threshold was higher than in the other etiology cases.
CONCLUSIONS
The NRT can be found in 82% of the cases during surgery. The responses obtained may vary according to etiology and the position of electrodes along the cochlea.
未标注
已推荐为24个月以下儿童植入人工耳蜗。需要使用客观测量方法来辅助言语处理器编程。电诱发复合电位（EAP）可通过神经反应遥测（NRT）进行评估，是这些客观测量方法之一。
目的
确定手术期间NRT系统记录EAP的频率，并描述其反应。
研究设计
横向队列临床研究。
材料与方法
对17名使用Nucleus 24型植入体的患者测量其阻抗和NRT。对反应进行分析，并与病因、听力损失持续时间和电极阵列位置进行比较。
结果
EAP很容易在顶端电极记录到，在耳硬化症和脑膜炎病例中，EAP阈值高于其他病因病例。
结论
手术期间82%的病例可记录到NRT。所获得的反应可能因病因和电极沿耳蜗的位置而异。
