Fixation nystagmus suppression in caloric tests was used in examination of 56 patients suffering from chronic remittent labyrinthopathy, acute labyrinthopathy, vestibular neuronitis, otosclerosis, adhesive otitis media, vertebrobasilar insufficiency, motor disease, chronic remittent vestibulopathy and neurinoma of the VIII nerve. The bithermal test (BT) with electronystagmography was made to calculate the fixation suppression index (FSI). Complete suppression of the caloric nystagmus in at least one BT test appeared to be the most frequent variant of the response (24 cases). This was not dependent on the severity of the vestibular analyzer lesion. In 3 cases FSI of the caloric nystagmus was rather high (> 0.50). Introduction of the period of glance fixation in performance of all the 4 BT tests may serve an additional method in differential diagnosis of the vestibular disorders. The fixation test results should be compared to findings obtained in the other vestibulometric tests.
在对56例患有慢性缓解性迷路病、急性迷路病、前庭神经炎、耳硬化症、粘连性中耳炎、椎基底动脉供血不足、运动疾病、慢性缓解性前庭病和第八神经神经瘤的患者进行检查时，采用了冷热试验中的注视性眼球震颤抑制。通过双眼冷热试验（BT）和眼震电图来计算注视抑制指数（FSI）。在至少一次BT试验中完全抑制冷热性眼球震颤似乎是最常见的反应类型（24例）。这与前庭分析器病变的严重程度无关。在3例中，冷热性眼球震颤的FSI相当高（>0.50）。在所有4次BT试验中引入注视期，可作为前庭疾病鉴别诊断的一种辅助方法。注视试验结果应与其他前庭功能测试的结果进行比较。
