影像导航系统用于鼻内镜手术探讨

Application of image-guidance system in endoscopic sinus surgery

目的：通过对影像导航系统引导下鼻内窥镜手术的临床分析，探讨影像导航技术在鼻内镜手术中应用的一些问题。方法回顾性分析21例影像导航系统下鼻内窥镜手术，其中额窦囊肿、额窦炎4例，鼻腔内翻乳头状瘤4例．真菌性鼻窦炎3例，蝶窦炎及囊肿3例，复杂及复发慢性鼻窦炎、鼻息肉7例。结果影像导航术前准备时间（包括配准、头架定位、常规器械注册等）10-18 min，平均12 min。21例手术区域影像标志与实体解剖标志间的误差均＜1mm，平均0．84mm。21例患者手术顺利完成，无手术并发症发生。结论影像导航系统可确认鼻眼及颅底的局部及相邻解剖标志，显示术野邻近的重要结构，减少手术的侵袭性和并发症。提高手术的精确性和安全性。

Objective To evaluate the advantages of image-guidance system in endoscopic sinus surgery.Meth-ods 21 endoscopic sinussurgery procedures were performed with the help of image guidance system,including 4 case of cyst of frontalsinus,4 case of inverted pipilloma,3 case of fungal sinusitis,3 cases of disease sphenoidal si-nus,7 cases of chronic sinusitis with or without nasal polyps.Results In all cases,the preoperative took 10-18min, mean 12min,the relativc accuracy was within 1mm,mean 0.84mm,which was between image in operative region and anatomical points on the body.No complication occurred.Conclusion Nasal endoscopy in combination with im-age-guidance systems provides accurate anatomical localization of nasal cavity,sinuses and anterior skull base.It al-so could raise the effectiveness and cut down surgical complications.
