One option for patients with single sided deafness (SSD) who experience problems with insufficient hearing in different surroundings is the treatment with percutaneous bone-anchored hearing aids. Common medical problems associated to a skin penetrating abutment can be avoided by active transcutaneous bone conduction hearing implants. The purpose of our study was to evaluate the benefit of an active transcutaneous bone conduction hearing implant in patients with SSD.
Patients suffering from SSD who are implanted with an active transcutaneous bone conduction hearing implant in retrosigmoidal position were audiologically analyzed. The audiological test battery included air and bone conduction thresholds, word recognition score (WRS) in quiet and speech intelligibility (Oldenburg Sentence Test [OLSA]) in noise. Patient satisfaction was evaluated with the Abbreviated Profile of Hearing Aid Benefit (APHAB) and the Bern-Benefit in Single-Sided Deafness (BBSS) questionnaire.
The monosyllable WRS and the signal-to-noise ratio (SNR) assessed by the OLSA was significantly better in all aided conditions. Also, the APHAB categories ease of communication and reverberation and the average benefit in the BBSS improved significantly if using the device.
The Bonebridge is a transcutaneous alternative to the well-established percutaneous bone conducting devices in patients with single sided deafness. An improvement in hearing in noise and quiet as well as a decrease of the head shadow effect can be expected.
对于在不同环境中听力不足而出现问题的单侧耳聋（SSD）患者，一种治疗选择是使用经皮骨锚式助听器。主动式经皮骨传导听力植入物可避免与皮肤穿透式基台相关的常见医疗问题。我们研究的目的是评估主动式经皮骨传导听力植入物对SSD患者的益处。
对在乙状窦后位置植入主动式经皮骨传导听力植入物的SSD患者进行听力学分析。听力学测试组合包括气导和骨导阈值、安静环境下的单词识别分数（WRS）以及噪声环境下的言语可懂度（奥尔登堡句子测试[OLSA]）。使用助听器益处简表（APHAB）和单侧耳聋的伯尔尼益处（BBSS）问卷评估患者满意度。
在所有助听条件下，单音节WRS以及通过OLSA评估的信噪比（SNR）均显著更好。此外，使用该设备时，APHAB中的交流便利性和混响类别以及BBSS中的平均益处均有显著改善。
对于单侧耳聋患者，骨桥（Bonebridge）是成熟的经皮骨传导装置的一种经皮替代方案。预计在噪声和安静环境下听力会有所改善，且头影效应会降低。
