颅内上皮样囊肿的临床特征与显微手术入路探讨

目的为了提高颅内上皮样囊肿（ＩＥＣ）的诊断水平与手术治疗效果。方法总结分析２１８例ＩＥＣ的临床征象、诊断方式、显微手术入路与疗效。结果２０３例肿瘤获全切除;１５例因肿瘤包膜与丘脑或脑干粘连紧密而行次全切除。５例于手术后２周内因脑干缺血、水肿或肺部感染死亡。１７６例获长期随访（平均５．６年）,有１７０例恢复良好;３例肿瘤有复发,需行再次手术切除。结论采用ＣＴ或ＭＲＩ进行诊断、合理选择手术入路并应用显微手术治疗ＩＥＣ,是行之有效的方法。

Clinical feature and probe of microsurgical approach for intracranial epidermoid cyst

Objective TO improve the diagnostic level and surgical curative effect of the intracranial epidermoid cyst (IEC). Methods The clinical materials included the clinical main manifestations ,diagnostic modes,microsurgical approach ,and outcome of 218 patients with IEC were analysed and summarized. Results Among the totalof 218cases, 203 cases got a total removal of the tumor, in the remaining 15 patients, adhesion tightly to the thalamusor brain stem made only subtotal removal of the capsule of the capsule of tumor. Five patients were died of brain stem ischemiaedema, or lung infection within two weeks postoperatively Long-term follow-up (mean 5.6 years) in 176 patientsrevealed good recovery of 170 patients , contrasted recurrence with 3 cases need to treat by another Operative management. Conclusion It is an effctive method that using the CT or MRI to diagnose, rational selection operative approch, and applying microsurgical technique to ramove the intracranial epidermoid cyst for these patients~ents.
