Petechial hemorrhages of the tympanic membrane in attempted suicide by hanging: A case report
Research output: Contribution to journal › Journal article › Research › peer-review
It is important to determine whether a person has been strangulated and the diagnosis is not always straightforward since ligature marks are not always present. In forensic medicine the physical examination recommended is careful inspection of the head and neck region, oral cavity, examination of the eyes including the conjunctiva on both the upper and lower eyelids and photo documentation. Petechial hemorrhages of the conjunctiva are considered marker of life threatening hanging or strangulation. Hemorrhage from ears, perforated tympanic membrane and haematotympanum are scarcely described in case reports of strangulated patients. To our knowledge we are the first to report petechial hemorrhages of the tympanic membrane in a patient following attempted suicide by hanging. We believe that the petechial hemorrhages develop from the capillaries located in lamina propria of the epidermal layer above the fibrous layer. This assumption is made on the basis of our assessment of a normal tympanic membrane with light microscopy. Petechial hemorrhages of the tympanic membrane might in fact be the only sign of life threatening pressure applied to the neck. This is a very important finding and prospective studies should be conducted for further clarification on the matter.
