Popis: | We describe five cases of fatally injured males (occupational accident, car driver, pedestrian, motorcyclist and suicidal jump from great height) with one universal autopsy finding - the presence of brain tissue in one or both auditory canals. Internal examination revealed that all victims had multiple head fractures with dura lacerations. In four cases, the petrous part of the temporal bone was fractured (hinge fracture), while in one case the fracture of both the petrous part of the temporal bones and the occipital bone (ring fracture) was present. In all of these cases, considerable pressure was applied to the head, pushing brain tissue equally in all directions (due to incompressibility of the tissue). The tissue followed the path of least resistance, going through the lacerated dura into the fractured petrous part of the temporal bones and finally reaching the middle ear cavity and auditory canal. This phenomenon is almost exclusively encountered in closed-head injuries. In an open-head injury, brain tissue would be expelled through the open bone fracture and scalp wound. The presence of brain tissue in the ears could indicate a hinge or ring fracture in a closed-head injury which occurred as the result of excessive impulse force or considerable pressure applied to the head, i.e. the head was compressed and/or squeezed. |
