【摘要】 目的：探讨眼震电图（ＥＮＧ）对诊断继发于桥小脑角胆脂瘤三叉神经痛的意义。方法：对６１例三叉神经痛患者进行术前系列ＥＮＧ和脑干电反应测听（ＡＢＲ）及颅脑ＣＴ检查。结果：源发性三叉神经痛患者３项检测均正常，而继发性尤其是对继发于桥小脑角胆脂瘤患者的检测可出现异常结果，以ＥＮＧ最为敏感。结论：在三叉神经痛型的桥小脑角胆脂瘤诊断中，ＥＮＧ是较敏感的检测方法。更多还原

【Abstract】 The results of electronstagmography (ENG ), auditory brainstem response (ABR) and or were investigated in 61 cas- es with trigeminal neuralgia(TN)asking for surgical treatment. The examination results were normal in primary TN, and abnormal in secondary TN, especially TN caused by cerebellopontile angle cholesteatoma, ENG changes were the most significant. In most of the cases, the ENG showed that caloric test was attenuated or disappeared, but spontaneous nystagmus (SN), head-shaking nystagmus(HSN) and damptal torsion swing test(DTST) were stimulative reactions on the lesion side. While brainstem was compressed, reduced nystagmus to one direction was found in optokinetic nystagmus. It is concluded that ENG is Useful for differential diagnosis of TN.更多还原
