Objective To retrospectively analyze 40 cases of hanging and 33 cases of ligature strangulation in Kunming, to explore the neck injury characteristics and similarities and differences of related asphyxia signs of corpses in hanging and ligature strangulation cases, in order to provide reference for forensic identification. Methods Statistics of hanging and ligature strangulation cases accepted by Kunming Municipal Public Security Bureau from 2000 to 2017 were collected. Data including the gender, age, injury tool, neck injury and related asphyxia signs of the deceased in hanging and ligature strangulation cases were statistically tested by SPSS 23.0. Results There were more males in hanging cases than females. However, there were more females than males in ligature strangulation cases. In hanging cases, suicide was common, while homicide was rare. In ligature strangulation cases, homicide was common, while suicide or accidental death was rare. The average age of the deceased in hanging cases were older than those in ligature strangulation cases. The ligature mark in hanging was usually above the thyroid cartilage. The ligature mark in ligature strangulation was usually at the same level of the thyroid cartilage. The most common vital reactions were exfoliation and subcutaneous hemorrhage at the ligature mark, common among the deceased in hanging cases. Hyoid fracture rate of the deceased in ligature strangulation cases was more common than those in hanging cases. Conclusion The gender, age distribution, position of ligature mark, detection rate of vital reactions at the ligature mark and hyoid fracture rate of the deceased can help distinguish hanging from ligature strangulation.
目的 回顾性分析昆明市40例缢吊案件和33例勒颈案件，探讨缢吊与勒颈案件尸体颈部损伤特点及相关窒息征象的异同，为法医学鉴定提供参考。方法 收集昆明市公安局2000年至2017年受理的缢吊与勒颈案件资料。将缢吊与勒颈案件中死者的性别、年龄、致伤工具、颈部损伤及相关窒息征象等数据用SPSS 23.0进行统计学检验。结果 缢吊案件中男性多于女性，而勒颈案件中女性多于男性。缢吊案件中自杀多见，他杀少见；勒颈案件中他杀多见，自杀或意外死亡少见。缢吊案件死者的平均年龄大于勒颈案件死者。缢吊的勒痕通常位于甲状软骨上方，勒颈的勒痕通常位于甲状软骨同一水平。勒痕处最常见的生活反应是表皮剥脱和皮下出血，多见于缢吊案件死者。勒颈案件死者的舌骨骨折率高于缢吊案件死者。结论 死者的性别、年龄分布、勒痕位置、勒痕处生活反应检出率及舌骨骨折率有助于缢吊与勒颈的鉴别。
