骨锚式助听器（BAHA）偶尔会因基台而引起软组织问题。由于Sophono没有基台穿透皮肤，因此认为Sophono没有与基台相关的软组织问题。另一方面，据报告，经皮器械的输出比经皮器械低10 - 15 dB。因此，在本研究中，从手术和听力学角度对Sophono和BAHA进行了比较。 我们回顾性分析了9例Sophono患者和10例BAHA患者的病历。在BAHA病例中，采用单一垂直切口，不使用皮肤薄化技术。我们比较了Sophono和BAHA的手术时间、伤口愈合时间、术后并发症、术后开机后听力恢复和术后气骨间隙。 Sophono的平均手术时间为60分钟，BAHA为25分钟。伤口愈合时间Sophono为14天，BAHA为28天。未观察到重大术中并发症。在随访期间，在2件器械中未观察到皮肤问题。双侧外耳道闭锁患者术后听力增益BAHA组为39.4 dB（n=4），Sophono组为25.5 dB（n=5）。然而，差异无统计学显著性。在本研究纳入的所有患者中，两组之间的气骨间隙差异在0.5 kHz时为16.6 dB，在4 kHz时为18.2 dB。BAHA在统计学上显著优于Sophono。 考虑到听力学结局，认为BAHA使用者的听力学获益大于Sophono使用者。然而，Sophono在美容效果方面优于BAHA和基台。Sophono无需日常皮肤保养，不会发生因基台而引起的软组织并发症。因此，在决定植入前，有必要对每件器械进行全面解释。
Bone-anchored hearing aids (BAHA) occasionally cause soft tissue problems due to abutment. Because Sophono does not have abutment penetrating skin, it is thought that Sophono has no soft tissue problem relating to abutment. On the other hand, transcutaneous device’s output is reported to be 10 to 15 dB lower than percutaneous device. Therefore, in this study, Sophono and BAHA were compared to each other from surgical and audiological points of view. We retrospectively reviewed the medical records of 9 Sophono patients and 10 BAHA patients. In BAHA cases, single vertical incision without skin thinning technique was done. We compared Sophono to BAHA by operation time, wound healing time, postoperative complications, postoperative hearing gain after switch on, and postoperative air-bone gap. The mean operation time was 60 minutes for Sophono and 25 minutes for BAHA. The wound healing time was 14 days for Sophono and 28 days for BAHA. No major intraoperative complication was observed. Skin problem was not observed in the 2 devices for the follow-up period. Postoperative hearing gain of bilateral aural atresia patients was 39.4 dB for BAHA (n=4) and 25.5 dB for Sophono (n=5). However, the difference was not statistically significant. In all patients included in this study, the difference of air-bone gap between two groups was 16.6 dB at 0.5 kHz and 18.2 dB at 4 kHz. BAHA was statistically significantly better than Sophono. Considering the audiologic outcome, BAHA users were thought to have more audiologic benefit than Sophono users. However, Sophono had advantages over BAHA with abutment in cosmetic outcome. Sophono needed no daily skin maintenance and soft tissue complication due to abutment would not happen in Sophono. Therefore, a full explanation about each device is necessary before deciding implantation.
