Our study aims to illustrate the clinical picture of otosclerosis in patients and the effect of surgery on the bone conduction thresholds compared to audiometry tests before surgery. A retrospective study included 36 patients that fit the inclusion criteria based on the patient's files and Pure Tone Audiometry of the patients before and after surgery. The questionnaire used is attached at the end of the study. According to Our sample, 77.8% were females, and 22.2% were males. The youngest was 17 years old, the eldest was 61, and the mean age was 38.2 years old. Hearing loss was the most common symptom in 100% of patients, while tinnitus was found in 66.7% and vertigo in 11%. The Injury was bilateral in 72% of the cases. Before surgery, the mean air conduction threshold (ACT) was 54.7 dB, the mean value of the air-bone gap (ABG) was 38.3 dB, and the mean bone conduction threshold (BCT) was 16.1 dB. Meanwhile, after the surgery, the mean BCT was 18.2 dB. Otosclerosis is more common in middle-aged females. Most cases are bilateral. Two-thirds of the cases of hearing loss were associated with tinnitus, while only a few had vertigo. A slight increase was noticed in BCTs after surgeries, especially at 4000 Hz. Stapedectomy caused a noticeable decrease in the values of BCTs on the frequency 4000 Hz. Stapedotomy improved the BCTs after surgery by about 5.3 dB at 4000 Hz.
我们的研究旨在阐明耳硬化症患者的临床情况，以及与术前听力测试相比，手术对骨导阈值的影响。一项回顾性研究纳入了36例符合纳入标准的患者，这些标准基于患者病历以及患者手术前后的纯音听力测试结果。所使用的调查问卷附在研究末尾。根据我们的样本，77.8%为女性，22.2%为男性。最年轻的患者为17岁，最年长的为61岁，平均年龄为38.2岁。听力损失是所有患者中最常见的症状，占100%，而耳鸣见于66.7%的患者，眩晕见于11%的患者。72%的病例为双侧病变。术前，平均气导阈值（ACT）为54.7dB，平均气骨导间距（ABG）为38.3dB，平均骨导阈值（BCT）为16.1dB。同时，术后平均BCT为18.2dB。耳硬化症在中年女性中更为常见。大多数病例为双侧性。三分之二的听力损失病例伴有耳鸣，而仅有少数伴有眩晕。术后BCT略有升高，尤其是在4000Hz处。镫骨切除术使4000Hz频率处的BCT值显著降低。镫骨切开术使术后4000Hz处的BCT提高了约5.3dB。
