摘要
目的 探讨国人鼻泪管冠状位CT扫描的最佳基线。②方法 随机选取 2 8例 (男 2 0例 ,女 8例 )正中矢状位切开的尸头 ,解剖鼻泪管 ,观察鼻泪管的走向并测量鼻泪管在矢状面上的投影与额最高点至前鼻棘连线的夹角 ,并根据此角度对随机选取的 5例完整尸头进行冠状位CT扫描 ,同一角度对扫描后的尸头进行冠状位切片 ,并比较两种方法所测鼻泪管是否吻合。③结果 鼻泪管在矢状面上的投影与额最高点至前鼻棘连线的夹角为8.74°± 1 .39° ,两种方法所测鼻泪管结果一致。④结论 依此角度进行冠状位CT扫描 。
Objective\ To evaluate the optimum coronal CT baseline for Chinese nasolacrimal duct.\ Methods\ Twenty eight (male 20,female 8)adult cadaveric heads were selected randomly for this study. The heads were cut along midsagittal plane. The nasolacrimal duct and its run were investigated, the angle between the line of the highest point of the front bone to anterior nasal spine measured. A coronal CT scanning was done for the five heads in random. The heads scanned were sliced on coronal plane same as scanning line. These two results were compared to make sure whether they were same.\ Results\ The angle between the coronal line of the nasolacrimal duct and the highest point of the frontal bone to the anterior spine was 8.74°± 1.39°, the result being the same. \ Conclusion\ A coronal CT scanning of nasolacrimal duct in accordance with this angle may completely display the whole picture of the organ.
