摘　　要：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。To display the structure of the Ostiomeatal Complex (OMC) more clearly,and provide clearer and more living imaging for safe functional endoscopic sinus operation and thoroughly eliminating the focus of disease,coronal CT scanning and 3-dimensional reconstruction were performed in 168 sinusitis patients (290 sides) and 107 patients with sinusitis and nasal polyposis (175sides ). The CT findings were compared with endoscopic examination and normal people were taken as control. The found of coronal CT and endoscopic examination are consistent in recognizing mucosal thinckening within nasal cavity and sinuses. Three-dimensional CT is more living than commen coronal CT in displaving the uncinate process and turbinates. Our conc1usion is that coronal CT scan poccesses high values for recognizing nasal sinus disease,anatomical variants,disease ex tent and adjacent structures of OMC. Three-dimensional reconstructed CT make the image of OMC more steroscopic,audio-visual and living.
