Abstract
Injuries to humans caused by wild animals, particularly bears, are rarely mentioned in the literature. The frequency of such injuries is high in Siberia, which is a territory surrounded by dense forests and is a habitat of brown bears. Only for the last 4 months (September - December) 4 episodes of bear attacks on humans were registered in Khakassia, Russia. We present a clinical case of rehabilitating a patient after a bear attack for multiple fragmentary fracture of the facial skeleton with displacement of bone fragments, subcutaneous emphysema of soft tissues of the face, parietal and right occipital regions, and paranasal sinus hemorrhage on the left side. The nature of the injury was enhanced by the trauma to the upper extremity, with which the patient defended himself against the animal. In addition to the damage to the face, the bear tried to open the cranium, which was evidenced by 4 furrows from the canines, 2 on the frontal and 2 on the occipital bones of the skull. The complex treatment of the patient included both maxillofacial and reconstructive surgery, and at the stage of outpatient treatment the formation of normotrophic scars with the help of neodymium laser and injections of heterogeneous composition consisting of micro-particles of "cross-linked" collagen of animal origin, placed in a gel identical to the natural extracellular matrix.
