皮层听觉诱发电位在人工耳蜗植入中的应用

Utility of Cortical Auditory Evoked Potentials in Cochlear Implantation

皮层听觉诱发电位(cortical auditory evoked potential,CAEP)是一种非侵入性脑电测量方式,能够通过波形的阈值、潜伏期与振幅评估听觉皮层的功能。近年来,CAEP的测试方式逐渐成熟,应用更加广泛。在人工耳蜗植入患者中,CAEP能够用于术前、术后听觉及言语能力、双耳听觉、音乐感知以及听觉可塑性的评估。相比较听性脑干反应(auditory brainstem response,ABR)、中潜伏期反应(middle latency response,MLR)等其它听觉诱发电位而言,CAEP潜伏期最长,能够反映完整听觉通路的情况、评价听觉皮层等高级中枢的功能及成熟度,具有独特优势。本文就CAEP在人工耳蜗患者中的研究进展进行综述。

Cortical auditory evoked potentials(CAEPs)are a non-invasive electroencephalography(EEG)measurement that can assess the function of the auditory cortex via changes in threshold,latency,and amplitude.Recently,as CAEP test techniques gradually mature,it is gaining wider use in the clinic.For patients with cochlear implants(CIs),CAEPs can be used for preoperative and postoperative auditory and speech abilities assessment,binaural hearing,music perception,and auditory cortex plasticity.Compared with other auditory evoked potentials,CAEPs reflect functioning of the complete auditory pathway and provide a means to evaluate the function and maturity of the auditory cortex with unique advantages.This article reviews the progress of researches on CAEPs in CI recipients.
