“…In the same group of patients there is also a risk of incorrect loading during dental implantation with the development of odontogenic maxillary sinusitis. In terms of surgery, it is advisable to pay special attention to a group of people with a large area of both the hooked process and the middle nasal concha, which is combined with larger than certain maximum transverse dimensions [18]. This should take into account the features of both general and local biomineralization of tissues in physiological and pathological processes [19], the importance of timely diagnosis of pathological processes of this localization, including in the presence of their unconventional course [20], as well as features of the influence of environmental factors on the morpho-functional state of the investigated tissues [21], and their regeneration [22,23].…”

The aim: Was to evaluate the anatomical variability of the frontal and maxillary sinuses, ostiomeatal complex components (OMC) and to identify factors that contribute to complications of inflammatory processes and development of odontogenic maxillary sinusitis. Materials and methods: The study involved assessment of 100 spiral computed tomograms (SCT) of human patients without pathological processes in the PNS area. The basic parameters of the anatomical structure of the ostiomeatal complex (the area of the hooked process and the middle nasal conch, their transverse dimensions, the density and dimensions of the natural connection), the thickness and the density of the lower wall of the maxillary and frontal sinuses were determined. These parameters were investigated by the method of uncertainty calculation. Results: The findings showed that the bone density of the maxillary sinus on the left was 57.713 ± 440.356 Hu (minimum), 1101.507 ± 613.4882 Hu (maximum); 96.2752 ± 395.0 and 1028.691 ± 620.4051 on the right, respectively, the density of the inferior frontal sinus wall on the right was 5.5179 ± 276.43 and 831.1607 ± 732.274, on the left 12.069 ± 310.56 and 898.293 ± 748, respectively. In the same way, the probable OMC structure parameters, in the range ± U at the confidence level p = 0.95, were calculated. Conclusions: Thus, some variants of the anatomical structure of the ostiomeatal complex can be a prerequisite for hypoventilation of PNS and, as a consequence, lead to inflammatory processes in them. Features of the same structure of the walls of the PNS are a prerequisite for the propagation of the inflammatory process in the surrounding tissues and the development of complications.

Background. The anatomical structure of the paranasal sinuses of a person predetermines the risk of development, diversity of presentation, possibility of complications and features of surgical treatment of rhinosinusitis. Objective: of our study was to determine the thickness and density of the walls of the maxillary and frontal sinuses, which are potentially dangerous in terms of the development of complications. Materials and methods: Our study involved 121 subjects without any ENT diseases, who underwent SCT examination due to the reasons that were not related to abnormalities of ENT organs. Thickness and density in the region of the lower (orbital) wall and posterior (cerebral) wall of the frontal sinus were calculated. Results and Discussion: The maximum density was characteristic of the lower wall of the frontal sinus under physiological conditions and appeared 107.96 ± 201.64 Hu, the minimum for the lower wall was -29.98 ± 208.54 Hu. The thickness of the bone tissue in the frontal sinus was 4.05 ± 2.04 mm. Conclusion: The minimum density and thickness of the lower and posterior walls of the frontal sinus and upper and lower walls of the maxillary sinus was established under physiological conditions. The density of the posterior wall was found to be 25.4% lower than the density of the lower wall, and the thickness 22.2% lower.

At the moment, there are many methods of analysis and classification aimed at building the most accurate and effective mathematical models that are widely used in medicine as a decision-making tool. Existing methods make it possible to identify the relationships between input and output variables in the sample, build models reflecting these relationships, compare them in terms of accuracy, profitability and costs, and choose the most effective model. The increase in the incidence of diabetes not only in the world, but also in Ukraine, dictates the need to introduce a mathematical apparatus for automatic diagnosis of the disease. Within the framework of the study, the classification of patients with diabetes by the logistic regression method was implemented. Python is used for software implementation.
