Postmortem computed tomography (pmCT) prior to forensic autopsy has become increasingly important in recent decades, especially in forensic documentation of single injuries, injury patterns, and causes of death. Postmortem decomposition gas formation can also be detected in pmCT scans, which might affect cochlear implant research in postmortem human temporal bones (TBs).
Fifty non-putrefied hanging fatalities within a 2-year period (January 2017 to December 2019) were included with 100 TBs. Each body underwent whole-body pmCT prior to forensic autopsy. PmCT scans were analyzed with respect to the presence of intracochlear gas despite the lack of putrefaction at autopsy by an experienced fellow neurotologist.
PmCT revealed gas formation in two individuals despite the lack of head trauma and putrefaction at postmortem examination and autopsy. Both individuals showed enclosed gas in the vestibule and the cochlea on both sides.
Intracochlear gas formation, most likely related to decomposition, may occur despite the lack of putrefaction at postmortem examination and autopsy and can be detected by pmCT. This finding seems to be rather rare in non-traumatic death cases but might affect cochlear pressure research in postmortem human TB.
近几十年来，法医尸检前的尸体计算机断层扫描（pmCT）变得越来越重要，特别是在单一损伤、损伤模式和死亡原因的法医记录方面。在pmCT扫描中也可以检测到死后分解气体的形成，这可能会影响死后人类颞骨（TBs）的人工耳蜗研究。
纳入了2年期间（2017年1月至2019年12月）50例非腐败缢死死亡病例，共100块颞骨。每具尸体在法医尸检前均进行了全身pmCT检查。尽管尸检时未出现腐败，但由一位经验丰富的神经耳科医生对pmCT扫描进行了耳蜗内气体存在情况的分析。
尽管尸检和死后检查时没有头部外伤和腐败现象，但pmCT显示两名个体出现了气体形成。两名个体双侧前庭和耳蜗内均出现了封闭气体。
尽管尸检和死后检查时未出现腐败现象，但仍可能发生最有可能与分解有关的耳蜗内气体形成，并且可以通过pmCT检测到。这一发现似乎在非创伤性死亡病例中相当罕见，但可能会影响死后人类颞骨的耳蜗压力研究。
