This study evaluated the audiometric outcomes and complications of simultaneous bone conduction device (BCD) implantation and auricular reconstruction, and the comparative effectiveness of three BCDs.
In total, 41 patients with bilateral microtia (ranging from 8 to 16 years old) who underwent combined surgery from January 2018 to January 2024 were retrospectively analyzed. Audiometric parameters (free-field thresholds and speech recognition scores) and complications were compared across the groups of patients who received the Baha Attract ( = 13), Sophono ( = 18), and Bonebridge ( = 10) devices.
Significant improvements occurred in aided vs. unaided conditions, with mean free-field threshold values of 57.6 ± 7.42 vs. 22.19 ± 6.40 dB ( < 0.001) and speech recognition threshold values of 69.42 ± 4.21 vs. 39.16 ± 6.78 dB ( < 0.001). No significant inter-group differences emerged in hearing gain ( > 0.05). Device-related complications included transient skin reactions, hematoma, and pressure erythema, and all were resolved conservatively. The patients' hearing threshold in a free field and speech recognition in quiet tests significantly improved after being implanted with the Baha Attract, Sophono, or Bonebridge hearing aid. There was no significant difference in hearing gain across frequencies between the subgroups. No patient in any of the subgroups reported major adverse events that affected the safety of the reconstructed auricle or the implant after the combined surgery.
The three implants demonstrated satisfactory hearing performance in children with bilateral microtia. Combined BCD implantation and auricle reconstruction surgery was shown to be safe and effective.
本研究评估了同期骨传导装置（BCD）植入与耳廓重建的听力测定结果及并发症，以及三种BCD的相对有效性。
回顾性分析了2018年1月至2024年1月期间接受联合手术的41例双侧小耳畸形患者（年龄8至16岁）。比较了接受Baha Attract（n = 13）、Sophono（n = 18）和Bonebridge（n = 10）装置的患者组之间的听力测定参数（自由声场阈值和言语识别分数）及并发症。
助听与未助听条件下有显著改善，平均自由声场阈值分别为57.6±7.42 dB与22.19±6.40 dB（P < 0.001），言语识别阈值分别为69.42±4.21 dB与39.16±6.78 dB（P < 0.001）。听力增益方面组间无显著差异（P > 0.05）。与装置相关的并发症包括短暂性皮肤反应、血肿和压力性红斑，均经保守治疗得到解决。植入Baha Attract、Sophono或Bonebridge助听器后，患者在自由声场中的听力阈值和安静测试中的言语识别能力显著提高。各亚组间不同频率的听力增益无显著差异。联合手术后，任何亚组中均无患者报告影响重建耳廓或植入物安全的重大不良事件。
这三种植入物在双侧小耳畸形儿童中显示出令人满意的听力表现。同期BCD植入与耳廓重建手术被证明是安全有效的。
