翼点入路显微手术切除颅中窝底肿瘤

Diagnosis and Treatment of Tumor in Middle Cranial Fossa

目的：探讨颅中窝底肿瘤的手术治疗的经验．方法：利用 ＣＴ、 ＭＲＩ、ＣＡＧ及Ｘ线平片等以确定肿瘤的部位、大小、形状、供血，明确其与周邻结构关系；选择翼点入路，采用显微手术切除颅中窝底肿瘤．结果：显微手术切除依中窝底肿瘤１５例，肿瘤全部切除１４例，全切除率９３．３３％，无手术死亡．１０例经７个月～５年随访，平均４．１年，肿瘤无复发．结论：采用显微手术能正确辨认肿瘤与周邻结构的关系，提高了肿瘤全切除率．

Objective: To discuss the diagnosis and treatment methods for the tumor in the middle cranial fossa. Methods: CT, MRI,CAG and X-ray plain film were performed to determine the location, size, shape and blood supply of tumor The relationship between tumor and surrounding structures also were detected. 15 cases were resected via the paternal approach with microsurgery techniques. Results: Complete removal was achieved in 14 of 15 cases (93.33%) and tumors were resected with microsurgery without death. No recurrence was seen in 10 patients followed up at a mean period of 4.1 years postoperatively. Conclusions: The relationships between the tumor and its surrounding structures are clear the operative field and it could increase the total lesion removal rate under microscope.
