This study reports the evaluation of the results after 72 stapedotomies in patients with bilateral otosclerosis. All pre- and postoperative audiological data, together with all relevant information of the operations, were stored in a data base and analyzed retrospectively. The Glasgow benefit plot (GBP) is a useful method to evaluate the hearing results of each individual ear after stapes surgery in a more functional way rather than from a technical standpoint. Therefore, it has been used to assess the benefit obtained after second-ear stapedotomy. From the results it appears that a second operation on the contralateral side increases the chances of achieving at least one 'normal'-hearing ear, and it makes symmetrical 'normal' hearing possible in the majority of the cases.
本研究报告了对72例双侧耳硬化症患者行镫骨切除术的结果评估。所有术前和术后的听力学数据，以及手术的所有相关信息，都存储在一个数据库中，并进行回顾性分析。格拉斯哥获益图（GBP）是一种有用的方法，它能以更具功能性的方式而非从技术角度评估镫骨手术后每只耳朵的听力结果。因此，它已被用于评估对侧耳行镫骨切除术后所获得的益处。从结果来看，对侧耳进行二次手术增加了至少有一只耳朵达到“正常”听力的机会，并且在大多数情况下能实现双侧对称的“正常”听力。
