There are many ways of presenting the treatment's results for otosclerosis. Because of loss of the uniform standard, it is impossible to compare these results between various health centres. But the most important is, which way of presenting seems to be the best.
The aim of the study was to propose a scheme of presenting the treatment's results for otosclerosis.
In order to devise method, medical documentation of 81 patients, treated for otosclerosis in Otolaryngological and Oncological Laryngology Clinic with Audiology and Phoniatrics Department, was analysed retrospectively.
The received results were analysed for each patient and divided into 3 groups: first - changes of the air conduction, second - changes of the air-bone gap, third - changes of the bone conduction. The value of the air-bone gap is a measure of surgeon's effectiveness interpreting as the reconstruction of the conductive chain in the middle ear. The loss of bone conduction before and after the operation can evaluate the improving hearing after the operation of otosklerosis due to overclosure and also can take under consideration the sensoneurinal hearing loss induced by moving of the stapes. Only comparison these three parameters is correct to evaluate the operation's results, especially the air conduction. So that de Bruijn et al. proposed a diagram, called Amsterdam Evaluation Hearing Plots - AEHPs. That diagram compares the pre-operative mean air-bone gap to post-operative change of loss of air - conduction. Thanks to that, the overclosure and post-operative sensorineurinal hearing loss were taken under consideration.
The presentation of the treatment's results for otosclerosis should include, besides the air-bone gap, the air conduction and bone conduction too. The AEHPs meet the requirements.
有多种方式呈现耳硬化症的治疗结果。由于缺乏统一标准，各医疗中心之间无法比较这些结果。但最重要的是，哪种呈现方式似乎是最佳的。
本研究的目的是提出一种耳硬化症治疗结果的呈现方案。
为设计方法，回顾性分析了在耳鼻喉科和肿瘤耳鼻喉科诊所听力与语音科接受耳硬化症治疗的81例患者的医疗记录。
对每位患者的所得结果进行分析，并分为3组：第一组——气导变化，第二组——气骨导间距变化，第三组——骨导变化。气骨导间距的值是衡量外科医生重建中耳传导链有效性的指标。手术前后骨导的损失可评估耳硬化症手术后由于过度封闭导致的听力改善情况，也可考虑镫骨移动引起的感音神经性听力损失。只有比较这三个参数才能正确评估手术结果，尤其是气导。因此，德布鲁因等人提出了一种图表，称为阿姆斯特丹听力评估图（AEHPs）。该图表比较术前平均气骨导间距与术后气导损失的变化。由此，过度封闭和术后感音神经性听力损失得以考虑在内。
耳硬化症治疗结果的呈现除气骨导间距外，还应包括气导和骨导。AEHPs符合要求。
