为了深入研究眼震电图（ＥＮＧ）对小脑桥脑角病变的诊断价值。方法：对经手术和病理检查证实的２４例桥小脑角病变的ＥＮＧ资料进行总结分析。所有患者均行ＥＮＧ系列检查，包括：扫视试验、凝视试验、平稳跟踪试验、视动性试验、位置试验、温度试验、固视试验共７项试验。ＥＮＧ检查与手术和病理检查结果进行对照分析。结果：ＥＮＧ网膜一眼反射试验障碍表明为中枢性病变而与周围性病变相鉴别；Ｂｒｕｎ’ｓ眼震等和一例管麻痹对桥小脑角病变的定位有重要价值。视跟踪试验和视动性试验可提供病变的侧别关系。对３ｃｍ以下小脑桥脑角病变如有温度试验的管麻痹则多表明为听神经瘤，如无管麻痹则可能为其它性质的病变。
In order to further study the diagnostic value of evoked electroencephalography (ENG) on cerebellar pontine angle lesions. Methods: The ENG data of 24 cases of cerebellopontine angle lesions confirmed by surgery and pathological examination were analyzed. ENG series examinations were performed in all patients, including: glance test, gaze test, steady tracking test, optokinetic test, position test, temperature test, and fixation test. ENG examination and surgical and pathological examination results were compared. RESULTS: Disturbance of ENG omental refraction test showed that it was a central lesion and was differentiated from peripheral lesions; Brun’s nystagmus and a tube paralysis were important in the localization of cerebellopontine angle lesions. Follow-up tests and optokinetic tests provide the side-to-side relationship of lesions. For cysts less than 3 cm in diameter, cysts with a temperature test are more likely to indicate an acoustic neuroma, and if there is no numbness, they may be of other nature.
