The Baha implant is increasingly becoming a common form of treatment for individuals with single-sided deafness (SSD). However, evidence-based guidelines for determining candidacy in these patients are not yet established.
The purpose of this study was to investigate the clinical utility of speech-in-noise testing as a part of the preoperative evaluation of the Baha device in patients with SSD.
The study design was a prospective cohort of 24 English-speaking adults comparing preoperative results on speech-in-noise measures using the Baha Cordelle II headband stimulator to postoperative results using the patient's external Baha processor.
Outcome measures included signal-to-noise ratio (SNR) loss as measured by the QuickSIN™ and scores of self-reported disability questionnaires.
Wilcoxon signed-rank test resulted in no significant difference between the preoperative and postoperative methods for measuring benefit on listening in noise tasks. Passing Bablok regression analysis showed the preoperative and postoperative results to be statistically equivalent, which suggests that postoperative results can be predicted during preoperative testing. Wilcoxon signed-rank test showed significant improvements in self-reported disability postoperatively.
The results support the use of speech-in-noise measures as an accurate predictor of overall benefit in patients with SSD prior to implantation.
骨锚式助听器（Baha）植入正日益成为单侧耳聋（SSD）患者的一种常见治疗方式。然而，针对这些患者确定植入适应症的循证指南尚未确立。
本研究的目的是调查言语噪声测试作为SSD患者Baha装置术前评估一部分的临床效用。
研究设计为一项前瞻性队列研究，纳入24名讲英语的成年人，比较使用Baha Cordelle II头带式刺激器进行言语噪声测量的术前结果与使用患者外部Baha处理器的术后结果。
结局指标包括通过QuickSIN™测量的信噪比（SNR）损失以及自我报告的残疾问卷得分。
Wilcoxon符号秩检验结果显示，术前和术后测量噪声环境下听力获益的方法之间无显著差异。通过Bablok回归分析表明术前和术后结果在统计学上等效，这表明术后结果可在术前测试期间进行预测。Wilcoxon符号秩检验显示术后自我报告的残疾情况有显著改善。
结果支持将言语噪声测量作为SSD患者植入前总体获益的准确预测指标。
