The aim of the paper was to perform a 64-slice CT evaluation of the main anatomic variants of paranasal sinuses.
From April 2005 to January 2006, 100 patients were chosen among all those that had undergone a paranasal sinuses CT examination. They were 45 women and 55 men, all aged between 18 and 70 years, mean age 46 years; they were all caucasian. This research has been conducted using a 64-slice Siemens Somatom Volume-Zoom multidetector Spiral CT. Para-nasal sinuses CT examination has been performed through a thin axial acquisition; the patient was lying on his back and the images were processed with multiplanar reconstruction (MPR). The anatomic variants considered in this study are: concha bullosa, Haller cells, uncinate process abnormalities, agger nasi cells, ethmoidal bulla, Onodi cell, middle turbinate curvature abnormalities.
In this research it has been noticed that 29% of patients are affected by concha bullosa, 5% by Haller cells and again 5% by uncinate process abnormalities; 52% are affected by agger nasi cells, 15% by ethmoidal bulla, 9% by Onodi cell and 11% by middle turbinate curvature abnormalities.
By using a 64-slice CT you can get a better quality of images in terms of spatial and temporal resolution. Osteomeatal complex structures are often featured by many anatomic variants. The most of the time, percentages are the same as recent researches have shown.
本文旨在对鼻窦的主要解剖变异进行64层CT评估。
2005年4月至2006年1月，从所有接受过鼻窦CT检查的患者中选取100例。其中女性45例，男性55例，年龄均在18至70岁之间，平均年龄46岁；均为白种人。本研究使用64层西门子Somatom Volume-Zoom多探测器螺旋CT进行。鼻窦CT检查通过薄层轴向采集进行；患者仰卧，图像采用多平面重建（MPR）处理。本研究中考虑的解剖变异包括：泡状鼻甲、哈勒氏细胞、钩突异常、鼻丘气房、筛泡、Onodi气房、中鼻甲弯曲异常。
本研究发现，29%的患者患有泡状鼻甲，5%患有哈勒氏细胞，5%患有钩突异常；52%患有鼻丘气房，15%患有筛泡，9%患有Onodi气房，11%患有中鼻甲弯曲异常。
使用64层CT在空间和时间分辨率方面可获得更高质量的图像。鼻窦复合体结构常具有多种解剖变异。大多数情况下，百分比与近期研究结果相同。
