摘　　要：目的探讨计算机辅助电磁影像导航系统在鼻内镜手术中的应用价值。方法回顾性分析22例患者，其中鼻窦炎、鼻息肉16例，内翻性乳头状瘤5例，上颌窦毛细血管瘤l例。所有病例均采用计算机辅助电磁影像导航系统及鼻内镜实施手术。结果影像导航术前准备时间最长10min，最短4min。22例患者术中实体解剖标志与手术区域影像标志间的误差≤1mm，影像导航可准确定位视神经管等解剖标志，无手术并发症发生。结论计算机辅助电磁影像导航系统与鼻内镜能很好地结合，辅助指导医师在术中定位鼻腔、鼻窦及前颅底等解剖标志，保护术野及其周围的重要结构。特别是在复杂的手术中，可提高手术的精确性和安全性，减少术中及术后并发症。Objective To evaluate the clinical application of computer-aided electromagnetic imaging navigation in nasal endoscopic surgery. Methods Twenty-two cases of nasal endoscopic surgery with intraoperative imaging navigation were retrospectively reviewed,including 16 eases of sinusitis with or without polyp; 5 cases of nasal inverting papilloma; 1 case of maxillary capillary hemangioma. All cases were operated with computer-aided electromagentic imaging navigation and nasal endoscope. Results The preoperative preparing time would take 4 - 10 minutes. In 22 cases, the localization accuracy between 3-D image landmarks of navigation system and actual anatomical landmarks was less than 1 ram. The optic nerve and other anatomical landmarks could be orientated accurately in intraoperative procedures. No complication occurred. Conclusions Nasal endoscope combined with computer-aided electromagnetic imaging navigation provides accurate anatomical localization of nasal cavity, sinuses and anterior skull base. It could improve the effectiveness and decrease surgical complications, especially in complicated cases.
