Abstract

Objective: To investigate the influence of cognitive factors on cochlear implant (CI) outcomes in post-lingually hearing-impaired adults, using a predictive model based on pre-implantation characteristics.

Design: Cumulative Link Mixed Models (CLMM) were developed to test the influence of cognitive factors such as memory (verbal and visual) and fluency on speech perception in noise across multiple postoperative time points.

Study sample: 84 patients (18-87 years) with bilateral severe to profound hearing loss were recruited during pre-cochlear implant assessment at a tertiary academic medical centre. Participants were stratified into poorer, average and better performers.

Results: Better preoperative verbal memory predicted superior speech perception-in-noise (SIN) performance. Congenital and progressive congenital hearing loss were associated with poorer SIN outcomes. Age and duration of hearing loss did not significantly predict CI outcomes. Longitudinal follow-up demonstrated ongoing improvement in speech-in-noise perception over time.

Conclusion: Preoperative cognitive assessment enhances prediction of CI outcomes. Early identification of Poorer Performers enables personalised, mechanism-based intervention strategies that may maximise CI benefits and improve long-term functional outcomes.

与人工耳蜗植入成功相关的个体间认知差异的综合建模：一项队列研究。

目的：利用基于人工耳蜗植入前特征的预测模型，探讨认知因素对成人后语言听力受损患者人工耳蜗植入（CI）结果的影响。设计：开发累积链接混合模型（CLMM）来测试认知因素，如记忆（口头和视觉）和流畅性对术后多个时间点噪声环境下语音感知的影响。研究样本：84例（18-87岁）双侧重度至重度听力损失患者在某三级学术医疗中心接受人工耳蜗植入前评估。参与者被分为表现较差、一般和较好。结果：术前较好的言语记忆预示着较好的语音噪声感知（SIN）表现。先天性和进行性先天性听力损失与较差的SIN结果相关。听力损失的年龄和持续时间不能显著预测CI结果。纵向随访表明，随着时间的推移，语音在噪音中的感知能力不断提高。结论：术前认知评估有助于CI预后的预测。早期识别表现较差的患者可以实现个性化的、基于机制的干预策略，从而最大限度地提高CI效益并改善长期功能结果。
