目的：探讨翼管高分辨率ＣＴ（ＨＲＣＴ）正常及病理的表现。方法：回顾性分析１００例正常成年人翼管和７２例病变累及翼管的病例。结果：正常成年人右侧翼管长度１４．００ｍｍ（１７．０１～１１．００ｍｍ），左侧翼管长度 １４．００ｍｍ（１８． ０５～１１． ０３ｍｍ），男女两者无明显差异（ Ｐ＞０． ０５）；翼管前口宽度 ２．００ｍｍ（０．８０～４．００ｍｍ），后口宽度１．４０ｍｍ（０．５０～２．８０ｍｍ）；８５％翼管向前内走向，两侧翼管前部距离２５ｍｍ（１７～３１ｍｍ），后部距离２７ｍｍ（１９～３５ｍｍ）；翼管与蝶窦下壁前后的距离分别为２．４ｍｍ和３．０ｍｍ，以上三组数值均有显著差异（ Ｐ＜ ０． ０５），但男女之间无明显差异（ Ｐ＞０． ０５）。正常成人翼管与鼻窦关系：位于有完整分隔的蝶窦下５５％，蝶窦内３１％，不对称分隔或无分隔下８％，上壁缺如与蝶窦交通６％。病变累及翼管病理改变分三种类型：扩大１０例（１３．９％）；狭窄１７例（２３，６％）。消失４５例（９９．５％）。结论：ＨＲＣＴ能很好显示翼管骨性结构，准确认识翼管正常表现及与邻近结构关系，可以发现翼管早期病变并指导临床治疗。
Objective: To investigate the normal and pathological features of high resolution CT (HRCT). Methods: A retrospective analysis of 100 cases of normal adult wing and 72 cases of lesions involving the wing of the case. Results: In normal adults, the length of the right wing was 14.00mm (17.01 ~ 11.00mm) and that of the left wing was 14.00mm (18.05 ~ 11.03mm). There was no significant difference between male and female (P> 0. 05). The width of the front of the wing pipe is 2.00mm (0.80 ~ 4.00mm) and the width of the rear mouth is 1.40mm (0.50 ~ 2.80mm). The 85% The distance between the anterior and posterior sides of the wing and the sphenoid sinus was 2.4 mm and 3.0 mm, respectively, with significant differences in the above three groups ( P <0.05), but there was no significant difference between men and women (P> 0.05). Normal adult wing tube and the relationship between the sinuses: located in a complete separation of the sphenoid sinus 55%, 31% within the sphenoid sinus, asymmetrically or without separation under 8%, the absence of the upper wall and sphenoid sinus traffic 6%. Pathological changes involving the pathological changes of the wing in three types: enlarged in 10 cases (13.9%); stenosis in 17 cases (23,6%). Disappeared in 45 cases (99.5%). CONCLUSION: HRCT can well display the bony structure of the vasculature. Accurately recognize the normal performance of the vasculature and the relationship with the adjacent structures, we can find the early lesions of the vasculature and guide the clinical treatment.
