Vestibular functions in twenty-five patients with otosclerosis were analyzed before and after undergoing stapes surgery. Vertigo was present preoperatively in 6 patients, which disappeared completely after 4-6 weeks of surgery in all the patients indicating the usefulness of stapedectomy. Patients with otosclerosis demonstrated hypoexcitability compared to controls, which was statistically significant for right cold and hot irrigation. Our results showed equal culoric abnormalities in patients with mixed hearing loss and conductive loss. Patients with obliterative focus at surgery had impaired vestibular functions compared to non-obliterative foci without any statistical significance. A longer piston used at surgery tends to produce more vestibular damage compared to a smaller piston. Finally, the degree of vestibular dysfunction seems to be inversely proportional to the hearing result.
对25例耳硬化症患者在接受镫骨手术前后的前庭功能进行了分析。术前有6例患者出现眩晕，术后4 - 6周所有患者的眩晕完全消失，表明镫骨切除术的有效性。与对照组相比，耳硬化症患者表现出兴奋性降低，这在右侧冷热灌注时具有统计学意义。我们的结果显示，混合性听力损失和传导性听力损失患者存在同等程度的冷热试验异常。手术中有闭塞性病灶的患者与无闭塞性病灶的患者相比，前庭功能受损，但无统计学意义。与较小的活塞相比，手术中使用较长的活塞往往会造成更多的前庭损伤。最后，前庭功能障碍的程度似乎与听力结果成反比。
