纵裂入路显微外科切除鞍区肿瘤的研究

目的 探讨分析纵裂人路切除鞍区大型或巨大型不同肿瘤的疗效.方法 对36例呈浸润性生长的、大或巨大型的垂体腺瘤、脑膜瘤、颅咽管瘤、胶质瘤、皮样囊肿等不同性质的鞍区肿瘤采用经纵裂入路的显微手术进行治疗.结果 在36例中,依据术中显微镜下所见及术后CT或MRI复查结果.29例全切,5例次全切,2例大部切除.无明显术后并发症,无死亡病例.术前视力、视野损害者26例,24例术后当天开始好转,无变化或加重1例.其中有内分泌症状者,术前闭经、泌乳14例,术后泌乳停止13例,1例较术前减少.18例功能性垂体腺瘤患者中接受随访12例,血激素水平恢复正常10例,较术前明显下降2例.2例肿瘤复发,均行放射治疗.证明手术治疗效果良好.结论 纵裂入路是鞍区大型浸润性生长肿瘤手术治疗的重要方式.

Research of microsurgery removing sellar region tumor by interhemispheric approach

OI To research the new interhemispheric approach treatments of removing different large or huge sellar region tumor. Methods To remove 36 cases of different infiltrated-growth large or huge sellar region tumors by interhemisphefic approach microsurgery. Results In the 36 cases, total removal was achieved in 29, subtotal in 5 and most-partly in 2, and without any severe complications or death occured. 12 in 18 functional pituitary adcnoma were followed up, 10 cases got recovery on hormone level, and the level in 2 cases reduced ob ously. 2 cases recurred, both received γ-knife treatment. Conclusion The new interhemispheric approach surgery is important for large or huge invasive sellar region tumor.
