Abstract. One of the most important and common tasks of forensic examination is to determine the viability of the injury and the time of its formation. Determining the viability of strangulation is of great importance to the investigating authorities and the court during the investigation. Forensic diagnosis of lifelong strangulation can be most justified only with a comprehensive macroscopic and microscopic examination of tissues and organs, taking into account the general asphyxiation and specific signs of strangulation asphyxia. Skin preparations with strangulation furrow, brain and lungs were selected as objects. All preparations were made according to generally accepted histological methods, stained with hematoxylin and eosin. This color is quite suitable for most issues in expert research. Microscopic examination of the brain, lungs and skin with a strangulation furrow does not meet modern requirements of evidence-based medicine to determine the viability of both the strangulation itself and the manifestations of the asphyxiation. The use of only routine staining with hematoxylin and eosin allows to investigate only general morphological changes that do not carry specific information that allows to accurately determine the viability of strangulation asphyxia. These symptoms are also found in other causes of death, but in fact they are signs of death that occurred quickly. More characteristic signs, such as focal acute alveolar emphysema, do not always occur. Examination of the skin of the neck with a strangulation furrow accurately reveals changes that indicate the mechanism of its formation by local compression of the skin. However, changes that make it possible to establish the viability of furrowing are rare and very limited. Classical microscopy is an extremely important element of diagnosis in forensic practice. But in cases of establishing the lifelong origin of both strangulation and asphyxia is not effective and uninformative and requires further study of objects by other, more sensitive methods of research, for example, using modern immunomorphological techniques.
