舌骨假阳性骨折12例分析

Analysis of False-positive Hyoid Fractures: 12 Forensic Identification Cases

目的探讨舌骨假阳性骨折形成的原因以及法医学鉴定要点。方法整理12例在实际检案中舌骨假阳性骨折案例资料并分析其形成原因。结果舌骨假阳性骨折主要是由于检验时人为操作(4例)以及先天性分离型舌骨(8例)误判所致。结论通过骨折周缘肌肉、软组织出血以及骨折断端检验,可以对人为操作因素致舌骨骨折、分离型舌骨等舌骨假阳性骨折与真性骨折进行区分。

Objective To study the causes of false-positive hyoid fractures and forensic identification. Methods Twelve cases of false-positive hyoid fractures were collected and analyzed. Results Improper dissection technique （4 cases） and congenital separation （8 cases） were the main reasons for false-positive hyoid fractures. Conclusion True fractures can be differentiated from false-positive hyoid fractures. False-positive hyoid fracture caused by improper dissection technique can be identified through examina- tion of peripheral muscle, soft tissue hemorrhage, and the characteristics of fracture end.
