摘　　要：目的探讨鼻腔及鼻窦内翻性乳头状瘤fNIP）的CT诊断价值。方法总结17例术前行鼻窦CT检查的NIP患者；所有患者均采用全身麻醉／局部麻醉下鼻内镜下切除病变。术中观察病变范围、骨质破坏情况等，并结合术前影像检查。结果所有患者术中所见病变情况与术前影像相比较，术前影像有局部骨增生者5例，但在鼻内镜手术中仅有3例发现有明显的骨质增生，较硬，偶尔呈松质骨样变化。术前影像发现有12例有不同部位及程度的骨质吸收破坏征象．表现为上颌窦内侧壁较多见、眶内侧壁、眶底壁、上颌窦后外侧壁及钩突等处骨质吸收、破坏，病变破坏的范围和部位与肿瘤的基底部、大小等有关。这与术中所见相符合。结论鼻腔及鼻窦内翻性乳头状瘤的CT表现具有一定的特点，CT除能够对其进行较准确诊断外．还可明确判断肿瘤的解剖位置及其与邻近解剖结构的毗邻关系。Objective To evaluate the value of CT in diagnosis of inverted papilloma of nasal cavity and nasal sinuses.Methods Retrospective analysis of 17 patients with inverted papilloma （NIP）, who had been performed CT examination before surgery, were all performed intranasal endoscopic lesion resection under para-anesthesia or local anesthesia. The extent of disease, bone destruction and images of CT before surgery were observed. Results Intraoperative findings and images before surgery were compared.Five cases of local bone hyperplasia were observed before surgery, but only 3 cases of endoscopic sinus surgery were found proliferation of bone or changes like cancellous bone. Preoperative imaging findings of 12 cases with different location and degree of bone resorption or damage, the common bone were maxillary sinus medial wall, the medial orbital wall, orbital floor wall, lateral wall of the maxillary sinus and uncinate process, etc. The scope and location of lesion were related to the base and the size of tumor. Conclusion The CT performances of nasal cavity and nasal sinus inverted papilloma have certain characteristics. CT can not only carry on the accurate diagnosis to it, but also may be clear about the judgment of tumor dissection position and with neighbor dissection structure adjoining the relations.
