目的探讨影像导航技术在鼻腔鼻窦内翻性乳头状瘤(NIP)手术中的应用价值。方法将68例行手术治疗NIP患者按时间顺序分为前、后两组,前组应用鼻内镜手术或鼻内镜手术+传统术式(2001年5月～2004年12月)34例,后组以前组术式为基础加用影像导航技术(2005年1月～2007年6月)34例,对两组术后复发率进行比较。结果应用影像导航技术的后组术后复发率低于前组,差异有统计学意义(P<0.05)。结论影像导航技术在鼻腔鼻窦内翻性乳头状瘤手术中能进行三维重建,具有定位准确、影像立体,不受组织移位和解剖复杂影响的优点,可降低术后的复发率。
Objective To explore the value of image navigation in the operation of nasal inverted papilloma (NIP). Methods Sixty-eight patients undergoing surgical treatment of NIP were divided into two groups according to time sequence: 34 cases in the former group underwent endoscopic sinus surgery or endoscopic sinus surgery plus conventional surgery (May 2001 to December 2004) After the group based on the previous group plus video navigation technology (January 2005 ~ June 2007) 34 cases of postoperative recurrence rates were compared. Results The average postoperative recurrence rate of the posterior group was lower than that of the former group (P <0.05). Conclusion Video navigation technique can reconstruct nasal inverted papilloma in three-dimensional reconstruction. It has the advantages of accurate positioning, three-dimensional image, not affected by tissue displacement and anatomic complications, and can reduce the postoperative recurrence rate.
