A previously unrecognized laryngeal injury in young female victims of manual strangulation is described. Twelve larynges that were retrospectively and prospectively collected at the Office of the Chief Coroner for Ontario (1982-1997) were used for this study. In all instances, the larynges were from cases of strangulation (mean age 27 +/- 10 years, range 20-46) with classical postmortem findings of asphyxia and either manual or combined manual and ligature strangulation. None of the larynges had fractures of the lamina of the thyroid cartilage, superior cornua, or cricoid cartilages. However, in 9 of the 12 cases (75%), sagittal sections revealed multifocal acute haemorrhages into the base of the superior cornua of the thyroid cartilage at the point of origin from the laminae. The presence of acute intra-cartilaginous haemorrhage into the larynx likely represents the disruption of small blood vessels due to elastic deformation of the flexible larynx during strangulation. The recognition of this form of laryngeal injuries broadens the pathological findings in cases of asphyxia associated with pressure on the neck.
本文描述了年轻女性手动勒颈受害者中一种先前未被认识的喉部损伤。本研究使用了安大略省首席验尸官办公室在1982年至1997年间回顾性和前瞻性收集的12个喉部标本。所有喉部标本均来自勒颈案件（平均年龄27±10岁，范围20 - 46岁），具有典型的窒息死后表现，包括手动勒颈或手动与绳索勒颈相结合。所有喉部标本均未出现甲状软骨板、上角或环状软骨骨折。然而，在12例中的9例（75%）中，矢状切面显示甲状腺软骨上角从板层起始处的基部有多灶性急性出血。喉部软骨内急性出血的存在可能代表了勒颈过程中柔性喉部弹性变形导致小血管破裂。认识到这种喉部损伤形式拓宽了与颈部受压相关窒息病例的病理发现。
