标准面移位进路术治疗颅中窝底前外侧良性肿瘤

目的：观察改良标准面移位进路术治疗颅中窝底前外侧良性肿瘤的可行性及效果。方法：对10例原发于翼腭窝、鼻咽部并向颅中窝海绵窦旁、颞下窝或翼颌间隙呈扩张性生长的较大良性肿瘤行单纯改良标准面移位进路和颅面联合进路2种术式切除，术中对面部切口、上颌骨拆卸、复位、固定、窦内黏膜取舍及鼻腔外侧壁保留等做了部分改进。结果：术后平均随访3年2个月，成功9例，死亡1例，无出血、感染和移位骨坏死脱出等并发症。结论：采用改良标准面移位进路术治疗颅中窝底前外侧良性肿瘤，手术安全，疗效好。

Experience in treating anterior-lateral benign tumor in middle craninal fossa base through standard facial translocation approach

Objective:To observe the feasibility and effect of improved standard facial translocation approach in treating anterior-lateral benign tumor in middle cranial fossa base.Method:We excised 10 cases of benign tumor originatin from pharynx nasalis of peterygopalatine fossa and expanding toward the cavernous sinus of middle cranial fossa,infratemporal fossa or pterygo-maxillary space.We ameliorated, facialincisioned, maxilladisassembled, reestablishment, fixation,maxillarymucosal option and remained lateral wall ofnasal cavity to some extent.Result:The mean time of following-up was 38 month postoperatively without complications of bleeding, infection and necrosis or prolapse of displacing bones.Nine patients were treated successfully, one died.Conclusion:Reforming facial translocation approach in treating anterior-lateral benign tumor in middle cranial fossa base was safe and obtained ideal curative effect in near future.
