经颅切除鞍区大型肿瘤手术入路探讨

目的探讨经颅切除鞍区大型肿瘤的手术入路。方法对13例位于鞍内-鞍上轴线上的大型肿瘤采用一侧额下经眶入路手术；11例鞍上巨大型肿瘤和侵袭至鞍区周邻部位的肿瘤经眶-翼点入路切除。结果肿瘤全切除9例，次全切除9例，大部分切除6例。术后死亡1例，余无严重并发症，恢复良好。结论该两种手术入路具有操作简便、显露良好、脑牵拉轻和并发症少等优点，适于鞍区大型肿瘤的经颅手术切除。

Study on the operation approach on tumors in sellar area through cranial cavity.

Objective To explore the operating approaches through cavity for ho tumors in sellar area. Methods The one side orbit-below frontal aopproach was used for 13 cases with large tumor on axial line from inside suprasellar and the orbit pteri- onal approach was selected for 11 cases with imp tumor in suprasellar area or outside the area. Results Total removal was achieved in 9 cases, subtotal in 9 cases and partial in 6 cases. 1 patient died after operation. The rest recovered well recoveered without serious complication. Conclusions The two approaches have the merits of simple technique, exposing well, gentle brain pulling and few complication, which are suitable for operation on the large tumor in sellar area.
