To evaluate laryngoscopic findings in hanging cases and to compare them with magnetic resonance imaging (MRI) and forensic autopsy results.
Postmortem nasolaryngofibroscopy and MRI of five people who died from hanging were performed. Three people who died from other causes than hanging were also examined with a flexible laryngofibroscope. The results were compared with injuries discovered during forensic autopsy.
In all five hanging cases, laryngofibroscopic investigation showed a vocal fold position in complete adduction confirmed by MRI. This position did not seem to be influenced by the intensity of the forces applied to neck or postmortem delay and cadaveric phenomena. The vocal cords of the three non-hanging deceased were found in the intermediate position. These findings could suggest that pressure applied to the cervical nervous and cartilaginous structures or their elongation during hanging could lead to closure of the glottis with vocal cord adduction maintained after death.
Laryngofibroscopic examination in hanging cases could be very useful in confirming the vital character of the hanging and understanding asphyxial phenomena in incomplete suspension without laryngeal crush.
评估悬吊案件中的喉镜检查结果，并将其与磁共振成像（MRI）和法医尸检结果进行比较。
对 5 例因悬吊而死亡的人进行了死后鼻咽喉纤维镜检查和 MRI。还对 3 例因其他原因而非悬吊而死亡的人进行了纤维喉镜检查。将结果与法医尸检中发现的损伤进行比较。
在所有 5 例悬吊案例中，纤维喉镜检查均显示 MRI 证实的声带完全内收位置。该位置似乎不受施加于颈部的力的强度或死后延迟和尸体现象的影响。3 例非悬吊死者的声带处于中间位置。这些发现可能表明，悬吊时颈部神经和软骨结构受到压力或其拉长，可能导致声门关闭，并在死后保持声带内收。
悬吊案例中的纤维喉镜检查对于确认悬吊的生命特征以及在没有喉骨裂的不完全悬吊中理解窒息现象非常有用。
