MPR在眼眶爆裂骨折诊断中的应用价值

MPR's Application for the Diagnosis of Orbital Blowout Fracture

目的探讨MPR在眶区外伤诊断中的应用价值。方法收集近五年来317例眼眶爆裂骨折的病例,系统分析病变在不同解剖平面的影像差异。结果单纯眶内壁骨折243例,占77.7%;单纯眶下壁骨折31例,占9.8%;骨折同时累及内壁及下壁38例,占11.9%;双侧眶内壁骨折5例,约占1.6%。其中合并鼻骨骨折81例,占25.6%。结论螺旋CT扫描MPR后处理图像能够更清晰直观的显示病变,并可减少误诊及漏诊率。

Objective To investigate the MPR＇s orbital trauma diagnosis. Methods In the past five years,317 cases of orbital blowout fracture, a systematic analysis of the disease in different anatomical differences in the two-dimensional image. Results 243 cases of orbital wall fracture,accounting for 77.7 percent; only 31 cases of interior orbital wall fracture,accounting for 9.8 percent; fracture at the same time, related to the wall,the wall of 38 cases,accounting for 11.9 percent; Bilateral orbital fracture in 5 cases,accounting for about 1.6 percent. In the 81 cases of nasal bone fracture of the merger,accounting for 25.6 percent. Conclusion through the application of different anatomical reconstruction more clearly show that disease can reduce the rate of misdiagnosis and missed diagnosis.
