目的 探讨桥小脑角(CPA)区表皮样囊肿继发三叉神经痛患者的临床特点和对手术结果的评价.方法回顾性分析我院2003～2010年收治的10例具有典型三叉神经痛症状的CPA区表皮样囊肿并进行手术治疗的患者,并对影像学记录进行同顾性分析.结果 7例肿瘤全切(70％),3例大部切除,无手术死亡.患者疼痛均完全缓解,随访疼痛无复发.结论 与血管压迫引起的三叉神经痛患者相比,继发于CPA区表皮样囊肿的三叉神经痛患者具有发病年龄较轻、疼痛持续时间较长的特点,即使是大部切除肿瘤也极少复发,但尚需长期随访.%Objective To evaluate the clinical characteristics and surgical outcome of cerebellopontine angle (CPA) epidermoids presenting with trigeminal neuralgia (TN). Methods Between 2003 and 2010, ten patients with typical symptoms of trigeminal neuralgia were found to have CPA epidermoids and treated surgically at our hospital. To analyze retrospectively the clinico-radiological records of these patients. Results Total resection was done in 7 patients (70% ), subtotal resection was done in 3 patients. No death related operation. During follow-up, no patients occurred recurrence of TN. Conclusions The clinical features of TN from CPA epidermoids are characterized by symptom onset at a younger age compared to TN from vascular causes. In addition to removal of the tumor, the possibility of vascular compression at the root entry zone of the trigeminal nerve will be kept in mind. If it exists, a microvascular decompression ( MVD) should be performed. Recurrence of tumor is rare in both total and subtotal removal cases, but long-term follow-up is required.
