陈旧与新鲜鼻骨骨折的法医学比较研究

Forensic Comparison of Old and Fresh Nasal Bone Fracture

目的探讨鼻骨陈旧与新鲜骨折影像征象的区别。方法回顾性分析本中心于2015年因鼻部损伤进行司法鉴定案件共34例,以临床症状体征与鼻骨骨折典型影像征象为参照,分析比对陈旧与新鲜骨折的差异。结果两组数据在鼻背部软组织肿胀、鼻出血、鼻黏膜肿胀、骨折断端影像学形态特征、影像学动态变化均存在统计学差异。结论在司法鉴定实践中必须十分注重临床资料及影像学征象多元要素相结合,避免鼻骨陈旧与新鲜骨折认定的偏差,确保鉴定结论的客观性与准确性。

Objective To explore the distinctions of image signs between old and fresh nasal osteal fractures. Methods A total of 34 cases were retrospectively analyzed of nasal injuries identified in our institute during the year of 2015. Referenced with the clinical symptoms and typical images of nasal fractures, the differences were statistically compared and analyzed between the old and fresh fractures of nasal bone. Results There were statistical differences between the two sets of data about nasal soft tissue swelling, nose bleeding, nasal mucosal swelling, fracture-end imaging characteristics and dynamic imaging change. Conclusion Attention must be paid into the combination of the multiple factors of clinical data and imaging manifestations so that the identification deviation can be avoided upon old and fresh nasal osteal fractures, thereby insuring the objectivity and accuracy of the appraisal conclusion.
