摘要
作者分析423例眼眶骨折的临床与CT资料。根据骨折的特点将眼眶骨折分为三类,即爆裂骨折、直接骨折及复合型骨折。爆裂骨折最多见,占52.72%,骨折发生于眶内、下壁,以单壁骨折较多。直接骨折占30.02%,以单壁骨折多见,并以外壁骨折较多。复合型骨折占17.26%,各壁均可发生,均为多壁骨折。眼眶骨折的直接征象是眶壁骨质连续性中断、粉碎及移位。副鼻窦内“泪滴”征是诊断眼眶下壁骨折的特异性间接征象。由于眶骨折后软组织变化(眼外肌)及邻近骨折的改变与治疗方法及预后直接相关,因此对CT征象的观察应全面。此外,作者还对目前眼眶CT检查存在的问题进行了讨论。
The clinical and CT findings of 423 patients with orbital fracture were studied.Ac-cording to the features of orbital fracture,they were classified into three catagories-blownout frac-ture,direct fracture and complicated fracture,The blown-out fracture was the most common,consti-tuting 52.72%,Most blown-out fractures involved the orbital floor. Less often the medial orbital wall was fractured either singly or in conjunction with fracture of the floor. Direct fractures consti-tuted 30.02%,Most direct fractures involved only the lateral wall. Complicated fractures comprised 17.26%。Most complicated fractures involved muItiple walls. Interruption of bome continuity,frag-ments and displacement of bone fragments were the direct signs. Teardrop appearance in the maxil-lary sinus was a specific indirect sign of inferior orbital fracture. In addition,the problems associated with CT scanning were also discussed.
