Abstract

Cochlear implants (CIs) provide a tool for hearing reconstruction. How to effectively and reasonably evaluate the auditory rehabilitation level of CI children has always been a difficult problem, especially for those with prelingual deafness. Many studies have used electroencephalograph (EEG) technology for CI users, which have shown that EEG is suitable for clinical postoperative evaluation. This study aims to explore changes of latencies and amplitudes of P1 wave in CI children under auditory stimulation. A pure tone at 1000 Hz was used as the stimuli to induce cortical auditory evoked potentials (CAEP). The characteristics of P1 wave were compared between normal hearing children and CI children over different implantation period. Results show that CI children started to have improved auditory perception after implantation, moreover, their P1 wave amplitude becomes similar to that of normal hearing children after six months. One year after implantation, the characteristics of P1 wave of CI children become similar to those of normal hearing children. Therefore, it seems that P1 could be used as an objective auditory rehabilitation assessing indicator for CI children.

P1作为人工耳蜗患儿听觉康复的客观评价指标

人工耳蜗为听力重建提供了一种工具。如何有效、合理地评价CI患儿的听觉康复水平一直是一个难题，尤其是语前耳聋患儿。许多研究将脑电图(EEG)技术用于CI使用者，表明EEG适用于临床术后评估。本研究旨在探讨听觉刺激下CI患儿P1波潜伏期和振幅的变化。以1000 Hz的纯音作为刺激诱发皮层听觉诱发电位(CAEP)。比较正常听力患儿和CI患儿在不同植入期的P1波特征。结果表明，CI患儿植入后听觉感知开始改善，6个月后P1波振幅与正常听力患儿相近。植入后1年，CI患儿的P1波特征与正常听力患儿相似。因此，P1可以作为CI患儿听觉康复的客观评估指标。
