为了寻求对鼻、鼻窦病变、窦口鼻道复合体（OMC）解剖结构有较好的显示方法，获得较为真实的影像，使鼻内窥镜手术更安全、可靠、彻底，对168例（290侧）鼻窦炎及107例（175侧）鼻窦炎伴鼻息肉患者行鼻窦冠状CT扫描，并对OMC进行三维重建，同时与内窥镜检查及正常组相对照。发现对鼻腔、鼻甲及窦胶粘膜增厚的诊断冠状CT显示与内镇检查基本一致。三维CT比普通冠状CT显示钩突、鼻甲形态更为真实、形象。结论认为冠状CT对了解鼻腔、鼻窦病变、OMC的解剖变异、病变范围、毗邻有重要价值，OMC的三维重建可使图像更直观、真实，并有立体感。
In order to seek the nasal and sinus lesions, ostium and nasal complex (OMC) anatomy shows a better way to obtain a more realistic image, make the endoscopic sinus surgery more secure, reliable and thorough, 168 cases (290 Side) sinusitis and 107 patients (175 sides) with sinusitis and nasal polyps underwent coronal CT scan. The OMC was reconstructed by three-dimensional reconstruction and compared with endoscopy and normal group. Found on the nasal cavity, turbinate and sinus mucosa thickening of the diagnosis of coronary CT showed basically the same with the town inspection. Three-dimensional CT than normal coronal CT showed uncinate process, turbinate morphology more real, image. Conclusion Coronal CT is of great value in understanding the pathological changes of the nasal cavity and paranasal sinus, the anatomical variation of OMC, the extent of the lesion and the adjacency. The three-dimensional reconstruction of OMC can make the image more intuitive, true and stereoscopic.
