Abstract
Fractures are one of the most common components in multiple and associated injuries. Fractures of the lower jaw are observed in 76%, of the upper jaw in 24%, a fracture of the zygomatic-orbital complex in 12%. The actual problem of modern traumatology is the violation of reparative osteogenesis with injuries combined with facial trauma. The duration of the consolidation of fractures is determined by the degree of microcirculation disorders in the fracture zone, changes in cellular and coagulation hemostasis and mineral metabolism. In this connection, increasing the effectiveness of treatment of fractures of the bones of the face on the basis of early diagnosis of vascular and hemostasiological changes is of great importance for practical health care.
Highlights
Fractures of the lower jaw are the most common among all fractures of the bones of the facial skeleton and, according to different authors, range from 75 to 96.5%, and 28-36% of the total number of inpatient dental patients [1]
When evaluating the hemostasis system, general parameters were determined using kits and reagents from TechnologiaStandard Barnaul, NPO Renam Moscow: activated partial thromboplastin time (APTT) according to Caen et al (1968); thrombin time according to Biggs, Macfarlane (1962); the level of soluble fibrin in plasma orthophenanthroline test according to V.A
Arkhipov; the concentration of fibrinogen in plasma according to Clauss; activity of antithrombin III (AT-III) according to Abildgaard; screening of disorders in the protein C system - according to the assessment of the normalized ratio, which was determined in the PPP before and after the introduction of the protein C activator into it; Studies of platelet hemostasis: spontaneous aggregation of platelets in the blood according to N.I
Summary
Fractures of the lower jaw are the most common among all fractures of the bones of the facial skeleton and, according to different authors, range from 75 to 96.5%, and 28-36% of the total number of inpatient dental patients [1]. In case of fractures of the lower jaw due to the presence of fixing structures in the oral cavity, microcirculation of periodontal tissues and the process of self-cleaning in the oral cavity are sharply disturbed [12] In this regard, the number of pathogenic microorganisms on the surface of the teeth and mucous membranes increases, and the likelihood of infection of the wound substrate increases [13]. The number of pathogenic microorganisms on the surface of the teeth and mucous membranes increases, and the likelihood of infection of the wound substrate increases [13] This is only a small part of the known factors that disrupt the processes of reparative regeneration in fractures of the lower jaw and contribute to the development of complications [14]
