目的探讨经鼻蝶入路二次手术切除垂体腺瘤的手术方法和技巧,并总结术后通过综合治疗增加缓解率及预防并发症的经验。方法回顾性分析同济医院神经外科2005年1月至2010年11月二次经鼻蝶入路垂体瘤手术治疗的45例患者的临床资料,对手术切除程度,术后视力和内分泌的变化及并发症,术后综合治疗方法等进行总结和分析。结果患者全切加次全切除率达到81.3%,术前视力有障碍者术后好转率100%,功能性垂体腺瘤患者40.9%恢复正常,余患者均有不同程度好转。无死亡病例,无严重并发症病例出现。结论对于垂体瘤复发或残余患者,若存在手术适应证,再次经鼻蝶手术依旧是疗效最确切且相对十分安全的治疗手段,可作为治疗首选,配合药物和（或）放疗的综合治疗将能进一步提高疗效。
