高分辨率CT冠状及横断位扫描在鼻骨骨折诊断中的应用

目的探讨高分辨率CT(HRCT)冠状及横断位扫描在鼻骨骨折诊断中的应用价值。方法20例鼻骨骨折患者均行X线和冠状及横断位HRCT扫描检查,回顾性分析X线及HRCT对鼻骨骨折的诊断价值。结果X线检查确诊鼻骨骨折13例(其中粉碎性骨折5例);20例患者经CT检查均发现鼻骨骨折,其中粉碎性骨折13例,线性骨折7例;合并上颌骨额突骨折5例,上颌窦骨折4例,额骨骨折1例,眼眶壁骨折4例,鼻中隔骨折1例,筛窦纸板骨折2例,鼻额缝分离1例。结论HRCT冠状及横断位扫描对鼻骨骨折的诊断有较高的临床应用价值,可作为鼻骨骨折的常规和首选检查方法。

The Practical Value of Axial plus Coronal Scanning High Resolution CT in the Diagnosis of Nasal Bone Fracture

Objective To investigate the practical value of axial plus coronal scanning high resolution CT (HRCT) in the diagnosis of nasal bone fracture.Methods X-ray and axial plus coronal scanning HRCT were performed in 20 cases with nasal bone fracture,and the diagnostic value of X-ray and HRCT in nasal bone fracture were analyzed retrospectively.Results 13 cases were diagnosed as nasal bone fracture by X-ray examination (smashing nasal bone fracture in 5 cases).20 cases had nasal bone fracture by CT examination,13 cases had smashing nasal bone fracture,7 cases had line fracture;5 cases combined with maxilla process fracture,4 cases had maxillary sinus fracture,1 case had frontal bone fracture,4 cases had orbit wall fracture,1 case had nasal septum fracture,2 cases had ethmoid sinus plate fracture and 1case had the displacement of nose forehead.Conclusion HRCT axial plus coronal scanning technology has a high practical value in the diagnosis of nasal bone fracture,which can be used as routine and the best device in the diagnosis of nasal bone fracture.
