摘要
目的：探讨显微导航系统（ＳＭＮ）及观察棒（ＳＴＮ）使用方法及辅助颅脑手术初步体会。方法：术前１天均行ＣＴ薄层扫描三维重建立体定位，先用导航仪定出切口大小和手术入路。开颅手术１４例采用直切口或弧形切口，３例采用马蹄形切口，３例经蝶窦入路，显微放大５～１５倍下切除肿瘤。结果：导航定位均准确，误差１～３ｍｍ以内，肿瘤全切除１７例，次全切除２例，１例脑积水置管准确，除多发性脑膜瘤，颅咽管瘤及巨大垂体腺瘤各１例需要输血外，其它均不必输血，无手术并发症。结论：显微导航具有定位准确、缩小骨窗、减少损伤和减少并发症等优点。
Objective:To introduce the SMN and pointer system and the preliminary clinical experienceMethods:CT imaging were obtained the day before operationSMN or pointer was used to assist in determining the position of the craniotomy or tumor boundariesLinear or curvilinear scalp incisions were used for resection the tumors under the microscope with magnifications of 5～15 times in 14 cases of craniotomyThe horseshoeshaped scalp flaps were used in 3 cases and the other three cases took transsphenoidal approachResults:SMN and pointer were reliable and accurateThe error was within 1～3mmfor all 19 cases brain tumor resections,17 took total excision,2 took subtotal excisionThe ventricular catheter of VP shunt was placed accurately in one patient with hydrocephalusNo patients need blood transfusion,except one multiple meningomas,one craniopharyngiomas and one pitutary macroadenomasNo operation complications were found in all 20 casesConclusion:The system is accurate,navigator aid that allows a small size scalp flap,reduces brain tissue disruption and diminishes operation complications
