目的 探讨CT早期诊断眼眶骨折的临床意义。方法 分析172例眼眶骨折的临床与CT资料,根据骨折特点,将眼眶骨折分为爆烈性骨折、直接骨折及复合型骨折。结果 直接骨折最多见,占55.81％,以单壁骨折多见,并以外壁骨折较多。爆裂骨折占31.40％,骨折发生于眶内下壁。复合型骨折占12.79％,各壁均可发生,为多壁骨折。眼眶骨折的直接征象是眶壁骨质连续中断、粉碎及移位。副鼻窦内“泪滴”征是眼眶下壁骨折的特异性间接征象。结论 由于眼眶骨折后常伴软组织及周围骨折的改变与治疗方法及预后密切相关,因此,眼眶骨折应全面观察,早期诊断。
Objective To investigate the clinical significance of CT in the early diagnosis of orbital fracture. Methods The clinical and CT data of 172 cases of orbital fractures were analyzed. According to the characteristics of fractures, orbital fractures were divided into severe fracture, direct fracture and complex fracture. Results The most common direct fractures, accounting for 55.81%, more common in single-wall fractures, and more fractures of the outer wall. Burst fractures accounted for 31.40%, fracture occurred in the inferior orbital wall. Composite fractures accounted for 12.79%, all walls can occur, multiwall fractures. Orbital fractures of the direct signs of continuous orbital bone disruption, crushing and displacement. Paranasal sinus “teardrop” sign is a specific indirect signs of suborbital fracture. Conclusion Because orbital fractures often accompanied by changes in soft tissue and surrounding fractures and treatment methods and prognosis are closely related, therefore, orbital fractures should be comprehensive observation, early diagnosis.
