125 patients suffering from otosclerosis underwent oto-neurological investigations preoperatively and again daily from the second to sixth day postoperatively. An abnormal ENG in the form of a spontaneous or positional nystagmus, directional preponderance or a diminished caloric reaction could be found preoperatively in 30% of the patients. No statistically significant difference between patients with or without abnormal ENG findings could be shown in the late postoperative hearing results of 3 years in a series of different types of operations. Nearly half of the patients had postoperative nystagmus. On the second day nystagmus beat towards the operated ear in 22.3% of the patients. On the sixth day there was nystagmus only in one-third of the patients and it then beat towards towards the operated ear in only 12.1% of the patients and away from the operated ear in 12.6%. No statistically significant correlation could be found between the nystagmus findings and the late hearing results after 3 years' observation in this series of different types of operation.
125例耳硬化症患者在术前及术后第2天至第6天每天进行耳神经学检查。术前，30%的患者存在异常眼震电图，表现为自发性或位置性眼球震颤、方向优势或冷热反应减弱。在一系列不同类型的手术中，术后3年的听力结果显示，有或无异常眼震电图结果的患者之间无统计学显著差异。近一半的患者术后出现眼球震颤。术后第2天，22.3%的患者眼球震颤朝向患侧耳。术后第6天，只有三分之一的患者出现眼球震颤，其中仅12.1%的患者眼球震颤朝向患侧耳，12.6%的患者眼球震颤远离患侧耳。在这一系列不同类型的手术中，经过3年观察，未发现眼球震颤结果与术后3年听力结果之间存在统计学显著相关性。
