The primary purpose of the present study was to investigate the relationship between postimplant electrically evoked auditory brainstem response (EABR) measures (wave V threshold, wave V latency, input-output functions) and auditory performance and speech intelligibility outcomes measured using parental rating scales, such as Categories of Auditory Performance (CAP; Archbold, Lutman, & Marshall, 1995) and the Speech Intelligibility Rating scale (SIR; Allen, Nikolopoulos, Dyar, & O'Donoghue, 2001), respectively. The secondary purpose was to evaluate the relationship between age at implantation and ratings on the CAP and SIR.
Forty children with congenital sensorineural hearing loss participated. Preimplant parental ratings on the CAP and SIR were obtained, and all the children underwent cochlear implantation. Intracochlear EABRs were recorded postimplantation. Postimplant parental ratings on the CAP and SIR were obtained. The relationships between EABR parameters and auditory performance and speech intelligibility outcomes were studied. The effect of age at implantation on auditory performance and speech intelligibility outcomes was also investigated.
A significant negative correlation was found between EABR wave V thresholds and SIR growth (r = -.415, p = .016). Children with better CAP growths tended to have lower wave V thresholds than those with poorer CAP growths. Age at implantation had an effect on the auditory performance as measured using the CAP.
The present study provides evidence for the relationship between wave V thresholds of the intracochlear EABR and auditory performance and speech intelligibility outcomes measured using parental rating scales in pediatric cochlear implant recipients. Data also indicate that early intervention has a positive impact on auditory performance outcomes.
本研究的主要目的是探讨植入后电诱发听觉脑干反应（EABR）指标（V波阈值、V波潜伏期、输入-输出函数）与使用家长评定量表测量的听觉表现及言语可懂度结果之间的关系，家长评定量表分别为听觉表现分类量表（CAP；阿奇博尔德、卢特曼和马歇尔，1995年）和言语可懂度评定量表（SIR；艾伦、尼科洛普洛斯、戴尔和奥多诺霍，2001年）。次要目的是评估植入年龄与CAP和SIR评分之间的关系。
40名先天性感音神经性听力损失儿童参与研究。获取植入前家长对CAP和SIR的评分，所有儿童均接受了人工耳蜗植入。植入后记录耳蜗内EABR。获取植入后家长对CAP和SIR的评分。研究EABR参数与听觉表现及言语可懂度结果之间的关系。还研究了植入年龄对听觉表现及言语可懂度结果的影响。
发现EABR的V波阈值与SIR增长之间存在显著负相关（r = -0.415，p = 0.016）。CAP增长较好的儿童的V波阈值往往低于CAP增长较差的儿童。植入年龄对使用CAP测量的听觉表现有影响。
本研究为小儿人工耳蜗植入受者耳蜗内EABR的V波阈值与使用家长评定量表测量的听觉表现及言语可懂度结果之间的关系提供了证据。数据还表明早期干预对听觉表现结果有积极影响。
