The Common Otology Database (COD) is a joint effort by an international group of otologists to organize audit with a standardized reporting method in middle ear surgery. The first results on hearing outcome of the COD are presented in this article.
The primary objective was to confirm the validity of the benchmark group by comparing hearing outcome results with previously reported results. The secondary objective was to describe the population, technical aspects, and hearing outcomes of stapes surgery.
Nonrandomized prospective multicenter audit.
Twenty tertiary-referral otologic centers.
Primary and revision stapes operations in patients with otosclerosis.
Air-bone gap (ABG), bone-conduction (BC) thresholds, and air-conduction (AC) thresholds were evaluated at 3 and 12 months according to the guidelines of the Committee on Hearing and Equilibrium for the evaluation of conductive hearing loss. Raw data were displayed in an Amsterdam Hearing Evaluation Plot.
In primary stapes surgeries, the postoperative ABG was closed to 10 dB or less in 63.6% and to 20 dB or less in 92.6% (median, 8.75 dB). In revision stapes surgeries, the postoperative ABG was closed to 10 dB in 41.2% and to 20 dB in 76.5% of cases (median, 11.25 dB). The overall mean postoperative ABG at 12 months was 10.38 dB compared with 28.75 dB preoperatively. Using laser to perform the fenestration results in a less pronounced BC improvement when compared with procedures without laser assistance. No statistically significant difference in ABG pure-tone average at 3 months could be demonstrated between the different prosthesis types.
Results of hearing outcome are similar to previous, primarily retrospective, single-center studies. Our data confirm the effectiveness of stapes surgery in patients with otosclerosis.
共同耳科学数据库（COD）是一组国际耳科医生合作的成果，旨在通过标准化的报告方法对中耳手术进行审核。本文首次报告了 COD 在听力结果方面的初步结果。
主要目的是通过将听力结果与先前报告的结果进行比较来确认基准组的有效性。次要目标是描述镫骨手术的人群、技术方面和听力结果。
非随机前瞻性多中心审核。
20 个三级转诊耳科中心。
耳硬化症患者的初次和翻修镫骨手术。
根据听力和平衡委员会评估传导性听力损失的指南，在 3 个月和 12 个月时评估气骨间隙（ABG）、骨导（BC）阈值和气导（AC）阈值。原始数据显示在阿姆斯特丹听力评估图中。
初次镫骨手术中，术后 ABG 在 63.6%的病例中接近 10dB 或更小，在 92.6%的病例中接近 20dB 或更小（中位数为 8.75dB）。在翻修镫骨手术中，术后 ABG 在 41.2%的病例中接近 10dB，在 76.5%的病例中接近 20dB（中位数为 11.25dB）。与术前的 28.75dB 相比，12 个月时的总体平均术后 ABG 为 10.38dB。与没有激光辅助的手术相比，使用激光进行开窗术会导致骨导改善不明显。在 3 个月时，不同假体类型之间的 ABG 纯音平均差异没有统计学意义。
听力结果与以前的主要是回顾性的单中心研究相似。我们的数据证实了镫骨手术在耳硬化症患者中的有效性。
