Abstract

Objective: To explore the results of revision stapes surgery within a multicentric cohort, focusing on hearing improvements and correlation with the type of postoperative hearing loss experienced and related findings during the revision procedure.

Methods: A retrospective study of 308 consecutive revision stapes surgeries performed ay 5 Otorhinolaryngologic Units in Pisa, Turin, Pavia, Piacenza, and Rome between 2010 and 2023 was accomplished.

Results: The most frequent causes leading to revision stapes surgery were prosthesis dislocation (56.1%), use of a short prosthesis during primary surgery (13.9%), and an eroded incus (17.2%). The median air conduction threshold significantly improved after revision surgery, while the bone conduction threshold remained stable.

Conclusions: Revision stapes surgery effectively improves hearing in patients with unsuccessful initial operations, with a significant reduction in the air-bone gap (ABG). The audiological results in our patients are favourable. ABG closure within 10 dB was achieved in 57.2% of cases and within 20 dB in 76% of cases. Stapes revision surgery is feasible and provides an acceptable success rate.

镫骨翻修术:术中发现和听力学结果。多中心研究。
目的:在一个多中心队列中探讨镫骨翻修手术的结果,重点关注听力改善及其与翻修过程中经历的术后听力损失类型和相关发现的相关性。方法:回顾性研究2010年至2023年在比萨、都灵、帕维亚、皮亚琴察和罗马的5个耳鼻喉科单位进行的308例连续镫骨翻修手术。结果:导致镫骨翻修手术最常见的原因是假体脱位(56.1%)、初次手术时使用短假体(13.9%)和牙块侵蚀(17.2%)。翻修手术后中位空气传导阈明显提高,而骨传导阈保持稳定。结论:镫骨翻修手术可有效改善初次手术不成功患者的听力,显著减少气骨间隙(ABG)。我们患者的听力学结果良好。57.2%的病例在10db内关闭,76%的病例在20db内关闭。镫骨修复手术是可行的,并提供了可接受的成功率。
