目的 :探讨桥小脑角占位性病变引起的继发性三叉神经痛的临床特征。方法 :回顾分析了 1 2例继发性三叉神经痛患者的临床资料 ,MRI检查 7例为桥小脑角胆脂瘤所致 ,5例为桥小脑角脑膜瘤所致 ;均经乙状窦后进路显微手术切除肿瘤。结果 :肿瘤切除术后无并发症发生 ;1 2例三叉神经痛全部治愈。随访 3～ 1 8个月 ,无复发。结论 :MRI检查是诊断继发性三叉神经痛的主要依据 ;乙状窦后进路显微手术是治疗继发性三叉神经痛的首选方法
Objective: To investigate the clinical features of secondary trigeminal neuralgia caused by occupying lesions of the cerebellopontine angle. Methods: A retrospective analysis of 12 cases of secondary trigeminal neuralgia in patients with clinical data, MRI examination of 7 cases of cerebellopontine angle caused by cholesteatoma, 5 cases of cerebellopontine angle meningioma caused by; retrograde retrograde sinus Road microsurgical resection of the tumor. Results: No complications occurred after tumor resection; 12 cases of trigeminal neuralgia were completely cured. Follow-up 3 ~ 18 months, no recurrence. Conclusion: MRI is the main basis for the diagnosis of secondary trigeminal neuralgia; sigmoid sinus posterior approach microsurgery is the preferred method of treatment of secondary trigeminal neuralgia
