The aim of this paper was evaluation of vertigo frequency in otosclerotic patients (group I N = 64) in comparison with control group (group II N = 20) and in people after stapedectomy (group III N = 64). Furthermore electronystagmographic recording spontaneous nystagmus, positional nystagmus were made. Computer analyses of ENG-recording and automatic calculation of directional preponderance and canal paresis were used. Vertigo was in 12% otosclerotic patients while in equal of age control group only in 5% subjects. Spontaneous nystagmus in 20% and positional nystagmus in 27% were recorded in otosclerotic patients while that took place in 10% and 15% control group respectively. Asymmetric reaction in-group I was in 21% cases and in 10% subject's in-group II. Real directional preponderance was in 18.8% otosclerotic patient's in-group I and it was absent in-group II. Obtained results revealed existence vestibule disturbances in otosclerotic patients. More frequent labyrinth objective symptoms were registered post stapedectomy. Vertigo in 21%, spontaneous nystagmus in 58%, positional nystagmus in 61%, asymmetric reaction in 48% was noted. Marks of vestibule and organ injury in otosclerosis and post stapedectomy were met. Vestibule disturbances were irritate and inconstant character. It is appears to be needed examination of balance system before stapedectomy in the planning of stapes operation and after operation on stapes. Presence of vestibular symptoms after stapes surgery is not cause less post stapedectomy improvement of hearing but sometimes postoperative improvement of hearing is better for lower frequencies in patients group with vestibular disturbances than in-patients without these symptoms.
本文旨在评估耳硬化症患者（第一组，N = 64）与对照组（第二组，N = 20）以及镫骨切除术后患者（第三组，N = 64）的眩晕频率。此外，还进行了眼震电图记录自发性眼震和位置性眼震。使用了眼震电图记录的计算机分析以及方向优势和半规管轻瘫的自动计算。耳硬化症患者中眩晕发生率为12%，而同龄对照组中仅5%的受试者有眩晕。耳硬化症患者中记录到20%有自发性眼震，27%有位置性眼震，而对照组中分别为10%和15%。第一组中21%的病例存在不对称反应，第二组中为10%的受试者。第一组中18.8%的耳硬化症患者存在真正的方向优势，而第二组中不存在。获得的结果显示耳硬化症患者存在前庭功能障碍。镫骨切除术后记录到更频繁的迷路客观症状。眩晕发生率为21%，自发性眼震发生率为58%，位置性眼震发生率为61%，不对称反应发生率为48%。观察到耳硬化症和镫骨切除术后前庭和器官损伤的迹象。前庭功能障碍具有刺激性和不稳定性。在镫骨手术规划中，似乎需要在镫骨切除术前和术后检查平衡系统。镫骨手术后前庭症状的存在并不影响镫骨切除术后听力的改善，但有时在前庭功能障碍患者组中，低频听力的术后改善比无前庭症状的患者更好。
