To compare the benefit of wireless contralateral routing of signal (CROS) technology to bone-anchored implant (BAI) technology in monaural listeners.
Prospective, single-subject.
Tertiary academic referral center.
Adult English speaking subjects using either a CROS hearing aid or BAI as treatment for unilateral severe-profound hearing loss.
Aided performance utilizing the subjects BAI or CROS hearing device.
Outcome measures included speech-in-noise perception using the QuickSIN (Etymotic Research, Elkgrove Village, IL, 2001) speech-in-noise test and localization ability using narrow and broadband stimuli. Performance was measured in the unaided and aided condition and compared with normal hearing controls. Subjective outcomes measures included the Speech Spatial and Qualities hearing scale and the Glasgow Hearing Aid Benefit Profile.
A significant improvement in speech-in-noise performance for monaural listeners (p < 0.0001) was observed, but there was no improvement in localization ability of either CROS or BAI users. There was no significant difference between CROS and BAI subject groups for either outcome measure. BAI recipients demonstrate higher initial disability and handicap over CROS hearing aid users. No significant difference was observed between treatment groups for subjective measures of post-treatment residual disability or satisfaction.
Our data demonstrate that both CROS and BAI systems provide significant benefit for monaural listeners. There is no significant difference between CROS or BAI systems for objective measures of speech-in-noise performance. CROS and BAI hearing devices do not provide any localization benefit in the horizontal plane for monaural listeners and there is no significant difference between systems.
比较无线对侧信号路由（CROS）技术与骨锚式植入（BAI）技术对单耳听力患者的益处。
前瞻性单受试者研究。
三级学术转诊中心。
使用CROS助听器或BAI治疗单侧重度至极重度听力损失的成年英语使用者。
使用受试者的BAI或CROS听力设备进行助听表现评估。
观察指标包括使用QuickSIN（伊顿声学研究公司，伊利诺伊州埃尔克格罗夫村，2001年）言语噪声测试评估的噪声环境下言语感知能力，以及使用窄带和宽带刺激评估的定位能力。在未助听和助听条件下测量表现，并与正常听力对照组进行比较。主观观察指标包括言语空间和质量听力量表以及格拉斯哥助听器益处概况。
观察到单耳听力患者在噪声环境下言语表现有显著改善（p<0.0001），但CROS或BAI使用者的定位能力均无改善。在任一观察指标上，CROS和BAI受试者组之间均无显著差异。BAI佩戴者相较于CROS助听器使用者，初始残疾和障碍程度更高。在治疗后残余残疾或满意度的主观测量方面，治疗组之间未观察到显著差异。
我们的数据表明，CROS和BAI系统对单耳听力患者均有显著益处。在噪声环境下言语表现的客观测量方面，CROS和BAI系统之间无显著差异。CROS和BAI听力设备在水平面内对单耳听力患者均未提供任何定位益处，且系统之间无显著差异。
