冠状CT扫描及三维重建在鼻科的应用

为了寻求对鼻、鼻窦病变，窦口鼻道复合体解剖结构有较好的显示方法，获得较为真实的影像，使鼻肉镜手术更安全，可靠、彻底，对１６８例鼻窦炎及１０７例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，同时与内镜检查及正常组相对照。

Application of coronal CT scan and three-dimensional reconstruction in rhinology

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.
