泡状中鼻甲引流通道的三维CT影像学观察

3D computed tomographic study of concha bullosa drainage pathway

目的:研究泡状中鼻甲形态及其引流通道的三维CT影像解剖学特征。方法:对90例(144侧)泡状中鼻甲的住院患者,采用16排螺旋CT扫描,用三维重建技术及影像工作站软件,分析泡状中鼻甲的形态和引流通道分布情况。结果:144侧泡状中鼻甲的形态和引流通道分布差异有统计学意义(P<0.05),广泛型、板状型、球状型3种类型泡状中鼻甲,广泛型最多见,前筛引流最多。个别泡状中鼻甲存在双向引流。结论:用三维重建技术及影像工作站软件,可以更精准分析泡状中鼻甲的影像学解剖特征,明确泡状中鼻甲疾病的临床诊断,强化鼻内镜下泡状中鼻甲的手术技巧。

Objective： The aim of this study is to study the related structures with concha bullosa drainage passway in inpatients with concha bullosa disease. Method： A total of 90 patients with peritubular middle turbinate （144 sides） were examined by 16-slice spiral CT. The distribution of the middle turbinate and the distribution of the drainage channel were analyzed by three-dimensional Result：The distribution of the morphology and drainage reconstruction technique and image workstation software. channel of 144 concha bullosa have statistically significant （P〈0.05）. There are 3 types of bubble in the middle turbinate： extensive gasification, lamina gasification, and globular gasification. We found that the mainly type was extensive gasification and the drainage pathways to ante- rior ethmoid sinus were much more than posterior ethmoid sinus. Individual concha hullosas had double way drain- ages to ethmoid sinus. Conclusion：The three-dimensional reconstruction technique and image workstation software can be more precisely analyze anatomical characteristics of concha bullosa, and clarify the clinical diagnosis of the turbinate middle turbinate disease and strengthen endoscopic surgical techniques.
