神经导航辅助显微手术在神经外科中的应用

目的：探讨神经导航技术在神经外科领域的应用前景和总结应用神经导航辅助显微神经外科手术切除位于脑重要功能区和深部小病灶的经验和体会。方法：我院2000年11月至2001年3月采用StealthStation神经导航系统辅助显微手术切除的颅内病灶18例，额叶6例（其中3例为于运动区），顶叶4例，枕叶2例，颞叶1例，桥小脑角2例，小脑半球3例，脑膜瘤6例，胶质瘤4例，炎性肉芽肿2例，血管网织细胞瘤3例，脂肪瘤，三叉神经纤维瘤和寄生虫感染各1例，结果：神经导航总体误差1．8－5．7mm，平均2．8mm，病灶全切除14例，次全切4例，位于运动区的3例小病灶，手术全切除后无任何神经功能障碍，结论：Stealth Station神经导航系统定位准确，尤其是对位于脑深部和重要功能区的小病灶，辅助显微手术效果显。

Clinical Application of Neuronavigator-assisted Microsurgery to Neurosurgical Practice

Objectives To evaluate the prospects of the application of neuronavigator-assisted techniques to neurosurgery, and to introduce our experiences in the application of this technique to surgery for lesions within the important function area or deeply situated in the brain tissue. Methods Eighteen patients with intracranial lesions underwent microneurosurgery under the guidance of neuronavigator system (StesalthStation). Of these lesions, 6 were located in the frontal lobe (3 in the motor area), 4 in the parietal lobe, 2 in the occipital lobe, 1 in the temporal lobe, 2 in the pontocerebellar angle, and 3 in the cerebellar hemisphere. These lesions include 6 meningioma, 4 glioma, 2 inflammatory granuloma, 3 hemangioblastoma, 1 lipoma, 1 trigem-inal neurofibroma and 1 parasite infection. Results Mean registration error was 2.8 mm (1.8~5.7 mm). Total resection of the lesion was achieved in 14 cases, subtotal in 4. Three of these lesions, which were relatively small in size and located in the motor area, were totally resected, leaving no any neurological deficit. Conclusion The neuronavigator (StesalthStation) system can provide valuable information in localization of the lesions especially those lesions with small size deeply located in the motor areas for the surgical operation.
