Modern medicine offers a wide spectrum of different hearing devices, and bone conduction implants can be found among them.
The presentation of the outcomes of the implantation of a new active bone conduction hearing implant - the Osia®, and its comparison with the well-known passive transcutaneous system - the Baha® Attract.
Eight adult patients with bilateral mixed hearing loss were randomly divided into two groups. Group 1 was implanted with the Osia®, and group 2 was implanted with the Baha® Attract. The details of the surgery were analyzed, along with the functional and audiological results.
In all the cases, the surgery was successful, and the healing uneventful. In both groups, it was observed that pure tone audiometry and speech audiometry in free field improved significantly after the implantation (mean gain in pure tone audiometry for the Osia group 42.8 dB SPL and for the Baha group 38.8 dB SPL). In the Osia group, the results after the surgery were much better than with the Baha® 5 Power processor on the Softband. The patients implanted with the Osia® evaluated the quality of their hearing as being superior to those implanted with the Baha® Attract. There was an evident improvement in the abbreviated profile of hearing aid benefit questionnaire and in the speech, spatial and qualities of hearing scale for both systems. In the abbreviated profile of hearing aid benefit, changes were more evident in the Osia group (in global score 49% vs. 37.2%).
Implantation of the Osia® is an effective treatment option for the patients with bilateral mixed hearing loss. The surgery is safe but more complex and time-consuming than the Baha® Attract implantation. The preliminary audiological results as well as the overall quality of life indicate that the Osia® is a better solution than the Baha® Attract. However, future studies should be carried out to make further observations in a larger group of patients, and with longer follow-up.
现代医学提供了广泛的不同听力设备，其中包括骨传导植入物。
介绍一种新型主动骨传导听力植入物-Osia®的结果，并将其与知名的经皮无源系统-Baha®Attract 进行比较。
将 8 名双侧混合性听力损失的成年患者随机分为两组。第 1 组植入 Osia®，第 2 组植入 Baha®Attract。分析了手术细节以及功能和听力结果。
所有病例手术均成功，愈合顺利。在两组中，植入后纯音听阈和自由场言语测听均显著改善（Osia 组平均纯音听阈增益 42.8dB SPL，Baha 组 38.8dB SPL）。在 Osia 组，手术后的结果明显优于 Baha®5 Power 处理器在软带上的结果。植入 Osia®的患者对其听力质量的评价优于植入 Baha®Attract 的患者。两个系统的助听获益简短问卷和言语、空间和听力质量量表均有明显改善。在助听获益简短问卷中，Osia 组的变化更为明显（总评分 49%比 37.2%）。
对于双侧混合性听力损失患者，植入 Osia®是一种有效的治疗选择。手术安全，但比 Baha®Attract 植入更为复杂和耗时。初步的听力结果以及整体生活质量表明，Osia®是比 Baha®Attract 更好的解决方案。然而，应进行进一步的研究，在更大的患者群体中进行更长期的随访观察。
