81例外伤性鼻部骨折的特点及其法医学鉴定分析

Study on characteristics of the nasal bone fracture and its forensic investigation

研究鼻部损伤后骨折的特点、确诊的方法及法医学鉴定的相关问题。 81例以鼻部外伤为主诉 ,经鼻骨拍摄X线侧位片 ( 62例加做鼻部CT扫描 )检见有鼻骨骨折的患者 ,进行法医临床学鉴定分析。单纯性线性骨折 19例 ,骨折移位者 11例 ,粉碎性、多发性骨折 4 0例 ,鼻骨骨折伴上颌骨额突骨折或 (及 )伴眶骨骨折 11例 ;轻伤 58例 ( 72 % ) ,未构成轻伤 2 3例 ( 2 8% )。多数鼻骨骨折为粉碎性、多发性 ,且可伴有其它部位骨折。鼻骨X线侧位片只能明确部分粉碎性骨折及部分移位明显的骨折 ,CT扫描能确定鼻部骨折形态。

For the purpose of studying the characteristics of nasal bone fracture, methods of diagnosis and the forensic investigation, 81 cases subjected to nose injuries in Jan.1998～Nov.1999 were analyzed. Patients were examined by lateral X-ray test. CT-scan was carried out in 62 cases. The results demonstrated that the linear fracture of nasal bone, displaced fracture, smashed and multiplex fracture, compound fracture of nasal bone accompanied by fracture of frontal process of maxilla and/or orbital bone were seen in 19, 11, 40 and 11 cases, respectively In 58 cases (72%), the injury were light. while in 23 cases the injury were not so severe as the light injury. X-ray examination could detect only part smashed nasal bone fracture and apparently displace ment of fractured bone,CT-scan could accurately determine the pattern of nasal bone fracture
