ObjectiveTo explore the characteristics of nasal bone fracture caused by blunt instrument, including the fracture types, the fracture repair, and the difference of manifestations between X-ray and CT. To provide reference for the identification.MethodsThe information of basic situation, fracture site, injury manner, diagnosis method, expert opinion of 95 adult nasal fracture cases caused by blunt object, which occurred in Gutian county of Fujian province from January 1999 to December 2013, were ana-lyzed by descriptive statistics. The identification conclusions of different injuries were compared accord-ing to new and old standards as well.ResultsThere were total 95 adults including 87 male and 8 fe-male. The fracture site and quantity have significant correlation with the nasal bone anatomical relations and the direction and size of the force. Compound fracture was most common. The fracture that could not be determined by X-ray could be clearly diagnosed by CT examination. According to new and old standards, different fracture types have different identification conclusions.ConclusionThere are gender differences in nasal bone fracture cases. Larger external force is easy to cause compound fracture. CT examination is significantly better than X-ray examination.%目的：探讨钝器致鼻部骨折种类、骨折及其修复的X线与CT表现差异等特点，为鉴定实践提供参考。方法对福建省古田县1999年1月至2013年12月发生的95例成年人因钝器致鼻部骨折的实际案例，按基本情况、骨折部位、致伤方式、确诊方式、鉴定意见等信息进行描述性统计，并对不同损伤根据新旧标准得出的鉴定意见进行比对。结果95例成年人中，男性87例，女性8例，骨折部位、数量与鼻骨解剖关系、受力大小和方向均有明显的关联，复合性骨折多见，X线检查无法确定的骨折，经CT检查均可明确诊断。不同骨折类型按新旧标准鉴定意见有所不同。结论鼻部骨折数存在性别差异，外力大时易出现复合性骨折，CT检查明显优于X线检查。
