中文摘要
目的： 本研究旨在使用扫频阻抗（SFI）仪验证耳硬化症的术前诊断。此外，还探讨了从SFI仪获得的测量值是否与镫骨足板的感知硬度相关。
研究设计： 回顾性队列研究。
地点： 三级转诊中心。
患者： 2020年9月至2023年12月期间在金泽大学医院及附属机构经手术确诊的37耳——22耳诊断为耳硬化症，15耳诊断为听骨链中断。
干预： (1) SFI、鼓室压测量、Carhart切迹和CT脱矿成像的诊断性能。(2) 评估镫骨足板硬度与SFI仪参数之间的相关性，特别是声压级变化（ΔSPL）和共振频率（RF）。
主要结局指标： SFI的正确诊断率。术前听力测量数据与SFI仪参数（ΔSPL和RF）之间的相关性。术前听力数据与镫骨足板感知硬度之间的相关性。
结果： SFI仪显示出最高的诊断准确性，正确诊断率为0.91，其次是Carhart切迹为0.73，CT成像和鼓室压测量为0.459。术前听力测量数据与SFI仪参数或镫骨足板感知硬度之间未观察到统计学显著相关性。
结论： 研究结果表明，与常规检测方式相比，SFI仪可能提供更优的诊断准确性。尽管未发现统计学显著相关性，但观察到的关联方向与预期的生物力学模型一致，即硬度增加将与更高的共振频率、降低的SPL调制和更大的AB间隙相关。SFI测量可能提供一种术前估计镫骨足板固定程度的方法。
英文摘要
OBJECTIVE: This study aimed to validate the preoperative diagnosis of otosclerosis using a Sweep Frequency Impedance (SFI) meter. In addition, it investigated whether the measurement values obtained from the SFI meter correlate with the perceived stiffness of the stapes footplate.
STUDY DESIGN: Retrospective cohort study.
SETTING: A tertiary referral center.
PATIENTS: Thirty-seven ears were surgically confirmed between September 2020 and December 2023 at Kanazawa University Hospital and affiliated institutions-22 diagnosed with otosclerosis and 15 with ossicular discontinuity.
INTERVENTIONS: (1) The diagnostic performance of SFI, tympanometry, the Carhart notch, and CT demineralization imaging. (2) Evaluation of the correlation between stapes footplate stiffness and SFI meter parameters, specifically the change in sound pressure level (ΔSPL) and the resonance frequency (RF).
MAIN OUTCOME MEASURES: Correct diagnosis rate of SFI. Correlation between preoperative audiometric data and SFI meter parameters (ΔSPL and RF). Correlation between preoperative hearing data and the perceived stiffness of the stapes footplate.
RESULTS: The SFI meter demonstrated the highest diagnostic accuracy, with a correct diagnosis rate of 0.91, followed by the Carhart notch at 0.73 and CT imaging and tympanometry at 0.459. No statistically significant correlations were observed between preoperative audiometric data and SFI meter parameters or the perceived stiffness of the stapes footplate.
CONCLUSIONS: The findings suggest that the SFI meter may provide superior diagnostic accuracy compared with conventional testing modalities. Although no statistically significant correlations were identified, the direction of the observed associations was consistent with the expected biomechanical model, in which increased stiffness would be associated with higher resonance frequency, reduced SPL modulation, and a larger AB gap. SFI measurements may offer a means to estimate the degree of stapes footplate fixation preoperatively.
