为了深入研究ENG对小脑桥脑角病变的诊断价值,本文对经手术和病理检查证实的24例桥小脑角病变的眼震电图资料进行总结分析.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,共七项试验.ENG检查结果与手术和病理检查结果进行对照分析.结果发现: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眼震等和一侧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,如无管麻痹则多表明为其它性质的病变.因此,具有一定的定性诊断价值.
In order to further investigate the diagnostic value of ENG on cerebellopontine angle lesions, 24 cases of cerebellopontine angle lesions confirmed by operation and pathology were reviewed. The ENG series were performed in all patients, including saccade Test, gaze test, smooth follow-up test, dynamic test, position test, temperature test, fixation test, a total of seven tests.ENG test results and surgical and pathological examination results were compared.Results: ENG retinal reflex Experimental disorders show central lesions and peripheral lesions differentiated; Brun’s nystagmus and side tube paralysis on the location of cerebellar angle lesion has important value.Track test and optokinetic test can provide side effects of the lesion; For cerebellar pontine lesions less than 3 cm, if the temperature test tube paralysis is more than that for acoustic neuroma, such as no paralysis is more for other lesions, therefore, has a certain qualitative diagnostic value.
