OBJECTIVES: The benefits of the bone-anchored hearing aid (BAHA) for rehabilitation of conductive and mixed hearing loss are well established. Recently, the BAHA was used to rehabilitate patients with single-sided deafness (SSD). In this study, the benefits of the BAHA in SSD are presented. STUDY DESIGN: Case series with planned data collection. SETTING: Tertiary referral center. SUBJECTS AND METHODS: Twenty-one consecutive adult patients with SSD underwent single-stage BAHA implantation on the side of deafness. Testing in sound field was performed using the hearing-in-noise test (HINT) in both unaided and aided conditions. Speech and noise signals were delivered through two speakers oriented in two test paradigms. The outcomes were expressed as signal-to-noise (S/N) ratios. Subjective benefit analyses were determined through two questionnaires: the Abbreviated Profile of Hearing Aid Benefit (APHAB) and the Glasgow Hearing Aid Benefit Profile (GHABP). RESULTS: All subjects demonstrated significant improvement in speech reception thresholds with the HINT using the BAHA, especially with the 90/270 speaker paradigm, in which the mean improvement over the unaided condition was 5.5 dB SPL (range, 2.0-11.0 dB; P=0.00001). Qualitative subjective outcome measures demonstrated additional benefits. CONCLUSION: In SSD patients, the BAHA provides significant subjective benefits and improves speech understanding in noise.

机译：目标：骨锚式助听器（BAHA）在传导性和混合性听力损失康复中的益处已得到公认。最近，BAHA被用于使单侧耳聋（SSD）的患者康复。在这项研究中，介绍了BAHA在SSD中的优势。研究设计：具有计划数据收集的病例系列。地点：第三级转诊中心。研究对象和方法：21名连续的成年SSD患者在耳聋一侧接受了单阶段BAHA植入。在无声和辅助条件下，均使用噪声听觉测试（HINT）进行了声场测试。语音和噪声信号通过面向两个测试范例的两个扬声器传递。结果以信噪比（S / N）表示。主观效益分析是通过两个调查表确定的：助听器效益简表（APHAB）和格拉斯哥助听器效益简表（GHABP）。结果：所有受试者在使用BAHA的HINT的情况下均表现出语音接收阈值的显着改善，尤其是在90/270说话者范式下，在无辅助条件下的平均改善为5.5 dB SPL（范围2.0-11.0 dB; P = 0.00001）。定性的主观结果指标显示出额外的好处。结论：在SSD患者中，BAHA提供了明显的主观益处，并改善了对噪声的言语理解。
