经终板入路切除视交叉前置型鞍区肿瘤

The translamina terminalis approach for microsurgical resection of anterochiasmatic sellar tumour

目的探讨经终板入路切除视交叉前置型鞍区肿瘤的手术方法。方法回顾性分析2001年2月至2007年5月间，经终板入路显微手术切除视交叉前置型鞍区肿瘤23例的临床资料及随访结果。结果23例患者镜下全切13例，次全切6例，大部分切除4例，无手术死亡；随访6个月-4年，复发3例。结论熟悉鞍区各解剖间隙的特点，并根据术中情况合理利用终板入路切除部分视交叉前置型鞍区肿瘤是一种行之有效的方法。娴熟的显微技巧，注意鞍区重要结构的保护、围手术期常见并发症的及时处理是获取良好疗效的基础。

Objective To study the operative approach and microsurgical technique of translamina terminalis approach on anterochiasmatic sellar tumour. Methods The clinical data and the follow-up result of 23 patients with anterochiasmatic sellar tumour who were treated surgically through translamina terminalis approach were analyzed retrospectively from February 2001 to May 2007. Results Among 23 patients, total resection was performed in 13 cases, secondary resection in 6 cases, partial resection in 4 cases. M1 patients had good results without operation death. Three recurred cases were found during the follow-up period of 6 months to 4 years. Conclusions The translamina terminalis approach for microsurgical resection of anterochiasmatic sellar tumour is an effective method by mastering anatomy characteristics of saddle area interspaces. Perfect microsurgical skill, protection of important structures in saddle area and treatment of complication in time ware the basement of achieving fine curative effect.
