A study was carried out to evaluate the results of stapes surgery in 53 cases of otosclerosis. The hearing function was measured pre- and postoperatively by means of conventional and high-frequency audiometry (Demlar 20K). The operative findings of the gradation of otosclerosis were compared with the pre- and postoperative audiometrical measurements. The results of this study point out that a clear relation exists between the preoperative high-tone audiogram and the gradation of otosclerosis. Stapedotomy does not influence the high-frequency threshold postoperatively. In conclusion, high-frequency audiometry can predict the state of stapes fixation in otosclerosis and this can be important in stapes surgery.
开展了一项研究以评估53例耳硬化症患者镫骨手术的结果。术前和术后通过传统和高频听力测定法（Demlar 20K）测量听力功能。将耳硬化症分级的手术结果与术前和术后的听力测量结果进行比较。本研究结果指出，术前高频听力图与耳硬化症分级之间存在明确的关系。镫骨切除术术后不影响高频阈值。总之，高频听力测定法可以预测耳硬化症中镫骨固定的状态，这在镫骨手术中可能很重要。
