摘　　要：目的:探讨多层螺旋CT(MSCT)对鼻骨骨折分型的临床价值。方法:39例鼻外伤患者经MSCT图像拆薄、二维和三维重建诊断为鼻骨骨折。然后根据直接骨折征象(D)、间接骨折征象(I)和有无伴发邻近骨骨折(C)进行分型和计数。结果:D型:无直接骨折征象3例(7.7%),线形骨折22例(56.4%),粉碎性骨折14例(35.9%);I型:无移位12例(30.8%),偏移10例(25.6%),塌陷15例(38.4%),既偏移又塌陷2例(5.1%);C型:无伴发邻近骨骨折14例(35.9%),伴发邻近骨骨折的25例(64.1%)。结论:通过DIC分型,MSCT能够准确描述鼻骨骨折的复杂情况。Objective： To evaluate the clinical value of multi-slice spiral CT for the typing of nasal bone fracture. Methods： Thirty-nine cases with nasal trauma were diagnosed as nasal bone fracture by post-procession of thin-slice recombination, two and three-dimensional reconstruction. Then these cases were typed and counted according to their direct signs of fracture（D）, indirect signs of fracture （I） and whether there was complicated fracture （C）. Results： Negative finding with 3 cases（7.7%）, linear fracture with 22 cases （56.4%）, and comminuted fracture with 14 cases（35.9%）were included in type D In type Ⅰ , 19. cases（30.8% ）were nasal bone fracture without displacement, 10 cases （25.6 %）were nasal bone fracture complicated by deviation, and 15 cases（38.4 % ）were nasal bone fracture complicated by depression, 2 cases （5.1 ~ ）were nasal bone fracture complicated by both deviation and depression. Positive diagnosis of complicated nasal bone fracture were 14 cases （35.9%）fracture, and negative diagnosis were 25 cases（64.1 %）. Conclusion： Conditions of nasal bone fracture can be described exactly by MSCT with DIC typing.
