摘　　要：目的　探讨翼管部位病变的HRCT表现及诊断价值。方法　回顾性分析经临床或病理证实 10 0例翼管部位的病变 ,皆行HRCT水平和冠状位扫描。结果　翼管均为继发性改变 ,分三种类型 :扩大 2 0例 (2 0 .0 % )、变窄 2 7例 (2 7.0 % )和消失 5 3例 (5 3 .0 % ) ,72例伴软组织肿块。结论　HRCT可清楚、直观显示翼管骨性结构 ,能发现翼管早期病变及准确判断病变范围 。Objective To evaluate the HRCT appearances and its value in diagnosis of diseases of pterygoid canal. Methods 100 patients proved by clinical or pathological materials were studied retrospectively.All CT scans were performed with both axial and coronal positions.Results In this series,the invasion of pterygoid canal were the secondary changes.The pathologic findings of pterygoid canal were enlargement in 20(20.0%),narrowing in 27(27.0%) and disappearance in 53(53.0%).72 cases simultaneously accompanied by soft tissues.Conclusion The bony structure of pterygoid canal can be showed well on HRCT,the early state of disease and the extent of the lesions at pterygoid canal can also be detected by HRCT,so that it can help to select the best plan in the treatment of diseases involving pterygoid canal.
