Abstract

Peripheral hearing loss is associated with the cross-modal re-organization of the auditory cortex, which can occur in both pre- and post-lingual deaf cases.

Background/objectives: Whether to rely on the visual cues in cases with severe hearing loss with adequate amplification is a matter of debate. So, this study aims to study visual evoked potentials (VEPs) in children with severe or profound HL, whether fitted with HAs or CIs.

Methods: This study included three groups of children matched in age and gender: normal hearing, children with hearing thresholds >70 dBHL and fitted with power HAs, and children fitted with CIs. All cases were subjected to pure tone audiometry (aided and unaided), speech discrimination scores, ophthalmic examinations, and visual evoked potentials (VEPs).

Results: SD% scores significantly improved with the use of VCs in both CI and HL groups, and a significantly higher P100 amplitude of VEPs in both CI and HL groups (more in children fitted with CIs).

Conclusions: Cross-modal reorganization in severe degrees of HL is of great benefit whether they are fitted with HAs or CIs.

重度听力损失的视觉依赖：视觉诱发电位（VEPs）研究。

外周性听力损失与听觉皮层的跨模态重组有关，这可能发生在语前和语后耳聋病例中。背景/目的：在听力损失严重的病例中，是否在适当放大的情况下依赖视觉线索是一个有争议的问题。因此，本研究旨在研究重度或重度HL患儿的视觉诱发电位（vep），无论是否配备HAs或CIs。方法：本研究将年龄和性别匹配的三组儿童分为听力正常儿童、听力阈值为bb0 ~ 70 dBHL并装有强力ha的儿童和装有CIs的儿童。所有病例均接受纯音测听（辅助和非辅助）、言语辨别评分、眼科检查和视觉诱发电位（vep）检查。结果：CI组和HL组的SD%评分均显著提高，CI组和HL组vep的P100振幅均显著升高（CI组和HL组的儿童更明显）。结论：对于重度HL患者，无论是否配用ha或ci，跨模态重组都有很大的益处。
