显微外科手术治疗三叉神经痛型桥小脑角胆脂瘤27例经验

背景与目的：颅内胆脂瘤多位于桥小脑角，桥小脑角胆脂瘤是继发性三叉神经痛最常见原因，本研究探讨三又神经痛型桥小脑角胆脂瘤的临床特点、有效诊断和治疗的方法。方法：回顾性总结27例三叉神经痛型桥小脑角胆脂瘤的诊治经过及疗效。结果：CT或（和）MRI确诊后行手术治疗，19例桥小脑角胆脂瘤得以全切，8例次全切，术后所有三叉神经痛及面肌痉挛完全消失，听力障碍明显好转。跟踪随访。1年后1例三叉神经痛复发。结论：三叉神经痛型桥小脑角胆脂瘤以三叉神经痛为首发症状．临床表现多不典型．年轻的患者如有三叉神经痛的症状时要高度怀疑此病，CT、MRI可提供诊断依据，常用的手术入路为枕下乙状窦后入路．手术方法得当．肿瘤切除后三叉神经痛的症状即停止。

Clinical Analysis of 27 Cases with Cholesteatmas in the Cerebellopontine Angle Region Presenting as Trigeminal Neuralgia

BACKGROUND & OBJECTIVE : Cholesteatomas is the common tumor found in the cerebellopontine angle and is the most common cause of secondary trigeminal neuralgia. In this article, we explored the methods of diagnosis and treatment for cholesteatomas in cerebellopontine angle region presenting as trigeminal neuralgia. METHODS: Clinical data of 27 cases with cerebellopontine angle cholesteatoma that primarily manifested with trigeminal neuralgia were analyzed retrospectively. RESULT: The preoperative CT or (and)...
