This study aimed to evaluate surgical and functional outcomes, in a tertiary referral centre, of two different types of semi-implantable transcutaneous bone conduction devices.
This study involved prospective data collection and review of patients implanted between November 2014 and December 2016. Glasgow Hearing Aid Inventory (Glasgow Hearing Aid Benefit Profile or Glasgow Hearing Aid Difference Profile) and Client Oriented Scale of Improvement were completed where appropriate. Surgical and audiological outcomes were recorded in the surgical notes.
Glasgow Hearing Aid Difference Profile and Glasgow Hearing Aid Benefit Profile showed similar mean score in the active and the passive transcutaneous bone conduction devices. Client Oriented Scale of Improvement showed improvements in listening situations. Post-operative speech reception threshold showed better mean threshold in the active transcutaneous bone conduction devices group when compared with the passive transcutaneous bone conduction devices group. No device failures or surgical complications existed in either group, with the surgical time being less in the passive transcutaneous bone conduction devices group.
Both devices are reliable semi-implantable transcutaneous bone conduction devices with excellent surgical and functional outcomes and patient satisfaction. Overall surgical time was much less in the passive transcutaneous bone conduction devices group with no necessity for pre-planning. This is much easier to remove with the possibility of conversion to other devices in the manufacturer's portfolio and wide-ranging wireless accessories. Further studies are needed to assess the longer-term results in a bigger population.
本研究旨在评估两种不同类型的半植入式经皮骨导装置在三级转诊中心的手术和功能结果。
本研究涉及前瞻性数据收集和回顾性分析 2014 年 11 月至 2016 年 12 月期间植入的患者。在适当的情况下，完成了格拉斯哥助听器清单（格拉斯哥助听器受益概况或格拉斯哥助听器差异概况）和以患者为导向的改善量表。手术和听力结果记录在手术记录中。
主动式和被动式经皮骨导装置的格拉斯哥助听器差异概况和格拉斯哥助听器受益概况的平均得分相似。以患者为导向的改善量表显示听力情况有所改善。与被动式经皮骨导装置组相比，主动式经皮骨导装置组的术后言语接受阈的平均阈值更好。两组均未发生器械故障或手术并发症，且被动式经皮骨导装置组的手术时间更短。
两种装置均为可靠的半植入式经皮骨导装置，具有出色的手术和功能结果以及患者满意度。总体手术时间在被动式经皮骨导装置组中明显更短，无需预先规划。该装置更容易移除，并且有可能转换为制造商产品组合中的其他设备，以及具有广泛的无线附件。需要进一步研究来评估更大人群的长期结果。
