前庭水管扩大行人工耳蜗植入言语康复效果分析

目的:探讨使用听觉和言语问卷分级评估比较前庭水管扩大伴耳蜗畸形与前庭水管扩大不伴耳蜗畸形耳聋患儿人工耳蜗植入术后的听觉言语康复效果.方法:按术前影像学检查将前庭水管扩大人工耳蜗植入患儿分为耳蜗正常组和耳蜗畸形组,并配对组合,应用问卷式听觉行为分级标准和言语识别率分级标准分别评估人工耳蜗植入患者术后的言语感知及言语产生能力,并对两组患者的耳蜗圈数与康复效果之间的相关性进行统计学分析.结果:经统计学分析,前庭水管扩大伴耳蜗畸形与前庭水管扩大伴耳蜗正常组行人工耳蜗植入术后听觉言语无显著性差异.结论:前庭水管扩大伴耳蜗畸形患者人工耳蜗植入术后,听力言语康复效果与耳蜗解剖结构正常植入者相同;人工耳蜗植入术可帮助前庭水管扩大伴耳蜗畸形的重度耳聋患者重建听力;听觉行为分级标准和言语识别率分级标准是评估人工耳蜗术后听觉言语能力的客观标准.

A questionnaire study on cochlear implantation in patients with large Vestibular aqueduct syndrome

Objective:To investigate the clinical experiences and access the Auditory performance and speech intelligibility of cochlear implantation in patients with large Vestibular aqueduct syndrome (LVAS).Method:Utilized in this survey were the questionnarires of leveldiscriminating standards of Categories of Auditory Performance (CAP) and Speech Intelligibility Rating criteria (SIR) to evaluate the speech perception and producing abilities after the the operation of cochlear implant.Results:After the regular rehabilitation,the long term follow-up of the auditory performance and speech intelligibility were very positive.There was no significant difference between normal group and malformed inner ear.Conclusion:The cochlear implantation can be performed safely in patients with LVAS.The results suggest that cochlear implantation could also provide long-term benefits to those malformed inner ear cases.
