Abstract
目的:回顾性复习眼眶爆裂骨折的CT资料,探讨CT检查方法对眼眶爆裂骨折的显示及诊断价值.方法:对226例患者行CT冠状位扫描和/或横断扫描,分析其CT表现的直接和间接征象.结果:本组226例病例,其中单纯内壁骨折105例(占46.46%),单纯下壁骨折13例(占5.75%),双壁(内、下壁)骨折23例(占10.18%),眼眶复合型骨折85例(占37.61%).眼眶爆裂骨折CT表现的直接征象为眶壁骨质断裂移位、粉碎和曲度异常.眼眶爆裂骨折CT表现的间接征象中眼外肌改变及眶内肌锥外积气在骨折中发生率较高.结论:冠状CT扫描是眼眶爆裂骨折的首选检查方法,眼眶爆裂骨折的间接征象尤其是眼外肌改变及眶内肌锥外积气对诊断有重要意义.
