人工耳蜗植入的最低年龄已降至12个月，以努力为发育早期听力损失的儿童提供听觉刺激。由于这些年幼儿童的行为测量是有限的，因此需要客观的测量，例如来自听神经的电诱发复合动作电位(EAP)，以便于对刺激的测量。级别要求。我们评估了在12至24个月大的植入手术的儿童中，由Nucleus 24神经反应遥测(NRT)系统记录的EAP。我们记录了37名这样的儿童的EAP(植入时的平均年龄为18.1+/-3.6月)。EAP波幅较大，阈值介于行为T和C水平之间。应用于EAP阈值的修正因子提供了对T水平的有用预测。EAP可以用来确保即使是非常年幼的儿童在设备激活时也能通过他们的人工耳蜗获得听觉刺激。
The minimum age for cochlear implantation has been reduced to 12 months in an effort to provide auditory stimulation to children With hearing loss during early development. Because behavioral measures in such young children are limited, objective measures such as the electrically evoked compound action potential (EAP) from the auditory nerve are needed to facilitate measurement of stimulation. level requirements. We assessed EAPs recorded by the Nucleus 24 neural response telemetry (NRT) system in children who underwent implantation between 12 and 24 months of age. We recorded EAPs in 37 such children (mean age at implantation, 18.1 +/- 3.6 months). The EAPs were of large amplitude, and thresholds fell between behavioral T and C levels. A correction factor applied to EAP thresholds provided useful predictions of T levels. The EAPs can be used to ensure that even very young children receive auditory stimulation with their cochlear implants upon device activation.
