Cortical auditory evoked potentials are a non-invasive tool that can provide objective information on maturation of the auditory pathways. This work was designed to study the role of cortical auditory evoked potential (P1) in assessment of the benefits of amplification and aural rehabilitation in hearing impaired children.
The study consisted of 31 children classified into 2 groups. Study group included 18 hearing impaired children ranging in age 4-14 years old and classified into two subgroups according to adequacy of aural rehabilitation. A control group consisted of 13 normal hearing children ranging in age from 5 to 13 years. All children were subjected to history taking, basic audiological evaluation, intelligence quotient and language assessment. Cortical auditory evoked potential (P1) was measured using synthesized speech syllable /da/ as a recording stimulus that was presented binaurally via a loudspeaker.
P1 was recorded in all children with significantly prolonged latencies in hearing impaired children with inadequate rehabilitation. P1 latency was correlated to hearing loss duration in hearing impaired children with inadequate aural rehabilitation. Auditory experience was correlated with P1 latency in hearing impaired children with adequate aural rehabilitation.
Cortical auditory evoked potential (P1) might provide a clinical tool to monitor aural rehabilitation outcome and to guide intervention choices.
皮质听觉诱发电位是一种非侵入性工具，可提供有关听觉通路成熟度的客观信息。本研究旨在探讨皮质听觉诱发电位（P1）在评估听力受损儿童放大及听觉康复效果中的作用。
该研究纳入31名儿童，分为2组。研究组包括18名年龄在4至14岁的听力受损儿童，根据听觉康复的充分程度分为两个亚组。对照组由13名年龄在5至13岁的听力正常儿童组成。所有儿童均接受病史采集、基本听力学评估、智商和语言评估。使用合成语音音节/da/作为记录刺激，通过扬声器双耳呈现，测量皮质听觉诱发电位（P1）。
所有儿童均记录到P1，康复不充分的听力受损儿童的潜伏期显著延长。在康复不充分的听力受损儿童中，P1潜伏期与听力损失持续时间相关。在康复充分的听力受损儿童中，听觉经验与P1潜伏期相关。
皮质听觉诱发电位（P1）可能提供一种临床工具，用于监测听觉康复结果并指导干预选择。
