目的探讨三叉神经痛型桥小脑角脑膜瘤的临床特点和治疗方法。方法回顾性分析我院2008年9月至2015年10月收治的16例以三叉神经痛为首发症状的桥小脑角脑膜瘤患者的临床资料及手术治疗效果。结果肿瘤全切除12例,次全切除3例,大部分切除1例。2例另行三叉神经感觉根部分切断术,1例行三叉神经微血管减压术。术后疼痛消失15例,疼痛好转1例。术后并发症包括面部麻木、暂时性面瘫、听力下降、动眼神经麻痹及颅内感染。术后平均随访45个月,无复发病例。结论桥小脑角脑膜瘤是继发性三叉神经痛的一个常见原因,手术治疗效果满意,术中要对三叉神经充分减压。
Objective To investigate the clinical features and treatment of cerebellopontine angle meningioma of trigeminal neuralgia. Methods A retrospective analysis of clinical data and surgical treatment of 16 patients with cerebellopontine angle meningioma treated with trigeminal neuralgia in our hospital from September 2008 to October 2015 was retrospectively analyzed. Results Total resection of tumor in 12 cases, subtotal resection in 3 cases, the majority of resection in 1 case. Two patients underwent partial trigeminal nerve root sectoral surgery, one case underwent trigeminal nerve microvascular decompression. Postoperative pain disappeared in 15 cases, 1 case of pain improved. Postoperative complications include facial numbness, temporary facial paralysis, hearing loss, oculomotor nerve paralysis and intracranial infection. After an average follow-up of 45 months, no recurrence. Conclusions The cerebellopontine angle meningioma is a common cause of secondary trigeminal neuralgia. The surgical treatment is satisfactory, and the trigeminal nerve should be decompressed during operation.
