计算机辅助导航技术在鼻窦及鼻颅底手术中的应用

目的:探讨计算机辅助导航技术在鼻窦及鼻颅底手术中的应用价值。方法:49例患者(复发性鼻窦炎、鼻息肉25例,鼻腔鼻窦肿瘤9例,脑脊液鼻漏7例,脑膜脑膨出2例,先天性后鼻孔闭锁4例,垂体瘤1例,中颅窝底异物1例)均在计算机辅助导航下行鼻内镜手术。结果:计算机辅助导航术前准备时间为5～13min,平均7min,靶点误差≤1.5mm。49例患者均顺利完成手术,无并发症出现。结论:计算机辅助导航系统有助于术者正确判断鼻窦、颅底及相邻的解剖标志,可提高手术的精确性和安全性,减少术中及术后并发症的发生。

Application of computer assisted navigation system in endoscopic sinus and skull base surgey

Objective:To evaluate the applicative value of computer assisted navigation system in endoscopic sinus and skull base surgery.Method:Forty-nine endoscopic surgery procedures were performed with the help of computer assisted navigation system,among which there were 25 cases of recurrent sinusitis and nasal polyps,9 cases of nasal and sinus tumour,7 cases of cerebrospinal fluid rhinorrhea,2 cases of meningoencephalocele,4 cases of congenital choanal atresia,1 case of pituitary tumor and 1 case of foreign body in middle cranial fossa.Result:The preoperative time was 5-13 minutes for preparation,7minutes in average.The target error was less than or equal to 1.5 mm.All the 49 cases had successful surgery without complications.Conclusion:Computer assisted navigation system can help the surgeon to determine the sinus,skull base and adjacent anatomic landmarks correctly,improve surgical accuracy and safety,and reduce intraoperative and postoperative complications.
