To evaluate the hearing results of a large series of primary stapedotomies, according to American Academy of Otolaryngology, Head and Neck Surgery guidelines and Amsterdam hearing evaluation plots.
Retrospective chart review.
The charts for 1369 consecutive stapedotomy cases were reviewed; 1145 cases of primary stapedotomy were included. Raw data from the audiometric database were evaluated using Amsterdam hearing evaluation plots. The effect on outcomes of using different audiological parameters was analysed.
A significant improvement was demonstrated in mean post-operative air conduction and speech reception thresholds, with no change in bone conduction. Air-bone gap closure of 10 dB or more was achieved in 82 per cent of cases. A 'dead ear' occurred in one patient (0.1 per cent).
This study reports the largest series of primary stapedotomies evaluated with Amsterdam hearing evaluation plots. This method enables visual identification of successful and unfavourable results, providing more accurate and detailed presentation of surgical outcomes.
根据美国耳鼻咽喉头颈外科学会指南和阿姆斯特丹听力评估图，评估大量原发性镫骨切除术的听力结果。
回顾性病历审查。
回顾了1369例连续镫骨切除术病例的病历；纳入1145例原发性镫骨切除术病例。使用阿姆斯特丹听力评估图评估听力测量数据库中的原始数据。分析了使用不同听力学参数对结果的影响。
术后平均气导和言语接受阈值有显著改善，骨导无变化。82%的病例气骨导间距缩小10 dB或更多。1例患者（0.1%）出现“死耳”。
本研究报告了使用阿姆斯特丹听力评估图评估的最大系列原发性镫骨切除术。这种方法能够直观地识别成功和不理想的结果，更准确、详细地呈现手术结果。
