Analysis of laryngeal fractures in decomposed bodies using microfocus computed tomography (mfCT)

Postmortem computed tomography (CT) is now routinely performed in forensic autopsies. Microfocus computed tomography (mfCT) has attracted recent attention because it can provide more detailed information than routine postmortem CT can. This feasibility study evaluated the usefulness of mfCT for examination of the hyoid bone and thyroid cartilage in cases of suspected strangulation, where advanced decomposition precludes detection of petechial hemorrhages and hemorrhages adjacent to fractures. The results show that mfCT was useful for identification of thin fracture lines in the fragile laryngeal structures. We suggest that mfCT should be considered for forensic autopsies in cases of suspected strangulation with advanced decomposition.
