影像导航技术在鼻腔鼻窦内翻性乳头状瘤手术中的应用

Application of image guidance in the surgical treatment of nasal inverted papilloma

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 evaluate the application of image guidance in the surgical treatment of nasal inverted papilloma. Methods Sixty-eight patients with nasal inverted papilloma were hospitalized and underwent operations. They were divided into two groups. Group 1 were hospitalized from May 2001 to Dec. 2004 and all underwent endoscope or/ and classic operation. Group 2 were hospitalized from Jan. 2005 to June 2007, and all underwent endoscope or/and classic operation using an image guidance technique. Results The relapse rate of group 2 was significantly lower than that of group 1 （ P 〈 0.05 ）. Conclusion Image guidance technique helps to reconstruct the 3 d structure with accurate positioning. It is not influenced by tissue displacement and complicated anatomical structure, so it can strikingly lower the relapse rate.
