目的：通过对眼眶爆裂骨折ＣＴ表现的分析，达到对本病早期诊断的目的。方法：作者回顾性分析了６４例（男５０，女１４）眼眶爆裂骨折的ＣＴ征象、好发部位和发病原因。病人的年龄在５～５７岁之间，平均３１．８ 岁。根据眼眶骨折的ＣＴ表现，将其分为三型：（１）单眶壁爆裂骨折；（２）多眶壁爆裂骨折；（３）混合型骨折（眼眶直接骨折合并有爆裂骨折）。结果：眼眶爆裂骨折的直接ＣＴ征象为眶壁骨质的连续性中断、粉碎、凹陷和曲度失常。其中单眶壁骨折３４ 例，多眶壁骨折７例，混合型骨折２３例。爆裂骨折最好发于眼眶内侧壁和眶底，占９４．８％ ，而混合型骨折眶外侧壁和内壁同时受累多见（占６０．８％ ）。结论：ＣＴ诊断眼眶爆裂骨折具有重要临床价值。
Objective: To analyze the CT manifestations of orbital blowout fractures to achieve the purpose of early diagnosis of this disease. Methods: The authors retrospectively analyzed 64 cases (male 50, female 14) orbital blowout fracture CT signs, the incidence of parts and causes. The patient’s age is between 5 and 57 years old, with an average of 31.8 years. According to CT manifestations of orbital fractures, it is divided into three types: (1) single orbital burst fracture; (2) orbital blowout fracture; (3) mixed fracture (orbital fracture with burst fracture). RESULTS: The direct CT signs of orbital blowout fractures were discontinuities in continuity of the orbital bone, comminution, depression and curvature disorders. Of which 34 cases of single orbital fracture, orbital fracture in 7 cases, 23 cases of mixed fracture. Burst fractures are best occurred in the medial orbital wall and orbital floor, accounting for 94.8%, while mixed fracture orbital wall and internal wall involvement more common (60.8%). Conclusion: CT has important clinical value in the diagnosis of orbital blowout fracture.
