使用人工耳蜗的脑白质弥漫性病变儿童的听觉与语言发育

中文摘要

背景： 本研究旨在探讨使用人工耳蜗（CIs）的脑白质弥漫性病变儿童的听觉、言语和语言发育情况。共纳入12名患有弥漫性脑白质病变（WMLs）的儿童人工耳蜗植入者，并与12名植入年龄匹配的无WMLs儿童进行比较。
方法： 用于比较表现的测量指标包括声场助听听阈、言语识别以及人工耳蜗植入后2年时的语言发育。
结果： 分析显示听觉察觉处于轻柔会话水平，两组之间的言语感知得分无统计学显著差异。然而，与对照组相比，患有WMLs的儿童在接受性和表达性语言年龄方面显著较低。
结论： 尽管听觉察觉得以保留，但脑白质弥漫性病变似乎显著影响语言理解和表达。这可能源于病变干扰了对言语和语言发育至关重要的认知过程。这一发现凸显了对脑白质弥漫性病变儿童进行全面的植入前评估、谨慎预后咨询以及量身定制康复策略的必要性。

英文摘要

BACKGROUND: The objective was to study the auditory and speech and language development in children with white matter diffused lesions using cochlear implants (CIs). A total of 12 pediatric CI recipients with diffused white matter lesions (WMLs) were compared with 12 implant age-matched children without WMLs.
METHODS: The measures included for comparison of performance were sound field aided thresholds, speech identification, and language development at 2 years post cochlear implantation.
RESULTS: Analysis revealed auditory detection was within the soft conversational level and no statistically significant difference was noticed in speech perception scores between the 2 groups. However, children with WMLs demonstrated significantly lower receptive and expressive language ages compared to the control group.
CONCLUSION: Despite preserved auditory detection, white matter diffuse lesions appear to significantly impact language comprehension and expression. This may result from lesions interfering with cognitive processes crucial for speech and language development. The finding highlights the need for comprehensive pre-implant evaluations, counseling on guarded prognosis and tailored rehabilitation strategies for children with white matter diffuse lesions.
