Abstract

Objectives

To evaluate and compare audiological outcomes of atresiaplasty and Bonebridge (BB) implantation in patients with unilateral congenital aural atresia (UCAA), to guide clinical decision-making.

Methods

Twenty-seven subjects diagnosed with UCAA were included in the study. Thirteen were implanted with the BB, while 14 undergone atresiaplasty. All patients underwent pre-and post-surgery examinations, including pure-tone audiometry, sound field threshold (SFT), speech reception threshold (SRT), word recognition score (WRS), and horizontal sound source localization tests.

Results

(1) Postoperatively, the average SFT decreased by 11.79 ± 5.93 dB HL in the atresiaplasty group and by 24.46 ± 9.36 dB HL in the BB group, with a significantly greater decrease in the BB group compared to the atresiaplasty group (P < 0.05). (2) Both groups demonstrated a significant improvement in average disyllabic WRS postoperatively under normal ear-masking conditions, with the BB group showing a significantly higher improvement than the atresiaplasty group. (3) When the speech signal was presented from the CAA side with noise from the normal hearing side, both surgical groups exhibited a significant decrease in postoperative signal-to-noise ratio compared to preoperative levels, with improvements of 2.14 ± 2.95 dB SNR in the atresiaplasty group and 4.92 ± 5.83 dB SNR in the BB group (P < 0.05). (4) The average minimum audible angle preoperative in the atresiaplasty group was 29.71 ± 18.42°, which decreased to 18.1 ± 10.07° at 6 months postoperatively, showing a statistically significant improvement (P < 0.05).

Conclusion

We concluded that both atresiaplasty and Bonebridge implantation can significantly improve speech perception under both quiet and noisy conditions in children with UCAA. BoneBridge implantation appears to provide better audiological outcomes than atresiaplasty. Atresiaplasty can significantly improve the accuracy of sound localization. No significant improvement in sound localization accuracy was observed in the short period after Bonebridge implantation. Further research should be conducted with a larger sample size and longer follow-up time.

单侧先天性耳道闭锁儿童的骨桥植入术与耳道成形术：听力结果比较研究

目的评估和比较单侧先天性耳道闭锁（UCAA）患者耳道成形术和骨桥（BB）植入术的听力效果，以指导临床决策。其中 13 人植入了 BB，14 人接受了耳道成形术。所有患者均接受了术前和术后检查，包括纯音测听、声场阈值（SFT）、言语接收阈值（SRT）、词汇识别评分（WRS）和水平声源定位测试。结果（1）术后，atresiaplasty 组的平均 SFT 下降了 11.79 ± 5.93 dB HL，BB 组的平均 SFT 下降了 24.46 ± 9.36 dB HL，与 atresiaplasty 组相比，BB 组的平均 SFT 下降幅度更大（P < 0.05）。(2）术后在正常掩耳条件下，两组患者的平均双音节 WRS 均有显著改善，其中 BB 组的改善幅度明显高于耳道成形术组。(3）当语音信号从 CAA 侧发出并伴有正常听力侧的噪声时，两组手术组的术后信噪比均比术前水平显著下降，其中闭锁成形术组的信噪比提高了 2.14 ± 2.95 dB，BB 组的信噪比提高了 4.92 ± 5.83 dB（P < 0.05）。(4) 闭锁成形术组术前的平均最小可听角为 29.71 ± 18.42°，术后 6 个月时降至 18.1 ± 10.07°，改善程度有统计学意义（P < 0.05）。与耳道成形术相比，骨桥植入术似乎能提供更好的听力效果。耳道成形术可显著提高声音定位的准确性。在骨桥植入术后的短时间内，声音定位的准确性没有明显改善。进一步的研究应采用更大的样本量和更长的随访时间。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
