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.
Case series with planned data collection.
Tertiary referral center.
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).
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.
In SSD patients, the BAHA provides significant subjective benefits and improves speech understanding in noise.
骨锚式助听器（BAHA）用于传导性和混合性听力损失康复的益处已得到充分证实。最近，BAHA被用于单侧耳聋（SSD）患者的康复。在本研究中，介绍了BAHA对SSD患者的益处。
有计划数据收集的病例系列研究。
三级转诊中心。
21例连续的成年SSD患者在耳聋侧接受了单阶段BAHA植入。在未佩戴和佩戴助听器的情况下，使用噪声中听力测试（HINT）在声场中进行测试。语音和噪声信号通过两个呈两种测试范式排列的扬声器传递。结果以信噪比（S/N）表示。通过两份问卷进行主观益处分析：助听器益处简明量表（APHAB）和格拉斯哥助听器益处量表（GHABP）。
所有受试者在使用BAHA进行HINT测试时，言语接受阈值均有显著改善，尤其是在90/270扬声器范式下，与未佩戴助听器的情况相比，平均改善了5.5 dB声压级（范围为2.0 - 11.0 dB；P = 0.00001）。定性主观结果测量显示了额外的益处。
在SSD患者中，BAHA提供了显著的主观益处，并改善了噪声中的言语理解。
