神经导航在经蝶垂体腺瘤切除术中的应用

目的探讨神经导航在经蝶入路垂体腺瘤显微切除术中的应用。方法在39例经蝶垂体腺瘤切除手术中，应用Stealth Station神经导航系统辅助定位。术前行CT连续薄层扫描，数据输入导航系统进行三维重建、注册。神经导航术中定位中线结构、蝶窦前壁、鞍底以及海绵窦、颈内动脉和斜坡等。结果本组注册误差1．06—3．22mm，平均（2．14±1．08）mm。手术时间66-92min，平均79min。肿瘤完全切除30例，次全切除9例。所有病人均未见严重并发症，9例术后出现一过性尿量增多。结论神经导航应用于经蝶入路垂体腺瘤切除术中，有助于提高手术的安全性、提高肿瘤全切率、降低并发症发生率。

Neuronavigator-assisted Microsurgery through Transsphenoidal Approach for Pituitary Adenoma(a Report of 39 Cases)

Objective To explore the curative effect of neuronavigator-assisted microsurgery through transsphenoidal approach on pituitary adenomas. Methods The transsphenoidal neuronavigator-assisted microsurgery was performed in 39 patients with pituitary adenomas. The data of preoperative continuous CT scan were infused into SteahhStation neuronavigation system and reconstructed in all the patients. Results The fiducial error ranged from 1.06 to 3.22 mm （mean, 2.14 mm±1.08 mm）. The operative duration was from 66 to 92 min （mean, 79 min）. The tumors were totally resected in 30 patients and subtotally in 9. There was no severe postoperative complication in all the patients, but transient polyuria occurred in 9 patients. Conclusion The neuronavigator-assisted the transsphenoidal surgery is helpful to enhancement of the security of transsphenoidal surgery, increase in the rate hof total resection of the adenomas and decrease in the surgical complications in the patients with pituitary adenomas.
