Summary

Forensic pathologists struggle to diagnose asphyxia due to a lack of universal signs. This study explores specific laryngeal hemorrhages and microfractures as key diagnostic indicators for strangulation.

Area of Science:

  • Forensic Pathology
  • Pathology
  • Medical Science

Background:

  • Diagnosing asphyxia postmortem presents challenges due to the absence of universally recognized pathognomonic signs.
  • Current diagnostic practices rely on a combination of individually insignificant observations, creating diagnostic ambiguity.

Purpose of the Study:

  • To address the diagnostic difficulties in postmortem asphyxia assessment.
  • To define minimally adequate diagnostic criteria for compressive neck injuries, particularly in cases of strangulation.

Main Methods:

  • Review of lesions commonly encountered in strangulation cases.
  • Detailed description of intracartilaginous laryngeal hemorrhages and laryngeal cartilage microfractures.
  • Discussion of a triad of laryngeal hemorrhages for morphological criteria development.

Main Results:

  • Intracartilaginous laryngeal hemorrhages and laryngeal cartilage microfractures possess unrecognized diagnostic value.
  • A triad of specific laryngeal hemorrhages is proposed for diagnosing strangulation without overt external injuries.
  • Several specific lesions show putative diagnostic value, though definitive criteria for minimal findings are still needed.

Conclusions:

  • Developing clear morphological criteria is crucial for diagnosing strangulation, especially in cases with subtle or absent external signs.
  • Further research is needed to establish definitive diagnostic criteria for minimal injury patterns in strangulation cases.
