Auditory and speech performance in cochlear implanted ANSD children

Abstract

Background: Auditory neuropathy spectrum disorder (ANSD) is a distinct type of SNHL that is characterized by the presence of otoacoustic emissions and/or cochlear microphonics. Cochlear implantation was initially not recommended for ANSD children, later studies showed variable outcomes among those subjects.

Objective: To assess the auditory and speech performance of cochlear implanted children with auditory neuropathy spectrum disorder (ANSD) and to compare these results to those obtained from cochlear implanted children with sensorineural hearing loss (SNHL)

Material and methods: 18 cochlear implanted children with ANSD and 40 cochlear implanted children with SNHL were included in this study. Auditory and speech performance results were compared across both subject groups using the Category of Auditory Performance (CAP) and Speech Intelligibility Rate (SIR) tests, with measurements recorded one year post implantation.

Results: Cochlear implanted children with ANSD showed clinically significant improvements that were comparable to those observed from cochlear implanted subjects without ANSD.

Conclusions: Children with ANSD benefit from early cochlear implantation and can reach similar auditory and speech performance results as that achieved by children without ANSD.

Chinese abstract

背景：听神经病变频谱障碍（ANSD）是一种独特的SNHL类型, 其特征是耳声发射和/或耳蜗微音的存在。最初不建议ANSD儿童植入人工耳蜗, 后来的研究显示, 这些受试者具有各不相同的结果。

目的：评价听神经病变频谱障碍（ANSD）儿童耳蜗植入后的听觉和言语功能, 并与感音神经性聋（SNHL）儿童耳蜗植入后的听觉和言语功能进行比较。

材料与方法：本研究包括18例人工耳蜗植入ANSD儿童和40例人工耳蜗植入SNHL儿童。使用听觉表现分类（CAP）和言语可懂率（SIR）测试对两个受试组的听觉和言语表现结果进行比较, 并记录植入后一年的测量结果。

结果：具人工耳蜗植入的ANSD患儿临床表现明显改善, 与人工耳蜗植入的非ANSD儿童的改善相比拟。

结论：ANSD患儿早期人工耳蜗植入后, 其听觉和言语表现与接受植入的非ANSD患儿相似。
