“…This combination can be especially dangerous in women during menopause [9]. The main prerequisite for the development of inflammatory processes in the paranasal sinuses is its inadequate ventilation [10]. Thus, it is extremely important to know the features of the anatomical variability of the components that make up the ostiomeatal complex.…”

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.

“…This inevitably entails a change in its microarchitectonics, thereby, a decrease in bone density, precipitating the the development of intracranial and intraorbital complications of rhinosinusitis. Moreover, a decrease in bone tissue density of the lower wall can lead to complications (Alekseeva et al 2019) during dental implantation due to improper load dosing during this procedure. The study showed that each patient required an individual approach to the diagnosis and treatment of rhinosinusitis.…”

The course of menopause transition (MT) is associated with peculiarities of alterations occurring in a woman’s body, in particular, in the structure of bone tissue. Considering that bones of the paranasal sinuses (BPNSs) play a natural defense role against the spread of dental infection, their structure is important in dentistry. However, no information was found pertaining to changes of BPNSs during MT – a time when dental maladies increase in many women.The aim of our study was to collate density of BPNSs with status of adrenal steroids in women during MT, since the pattern of their changes determines the course of MT.Cross-sectional associations were examined between bone density of PNSs assessed by Spiral Computed Tomography and Serum content of testosterone (T), sex hormone binding globulin (SHBG), free androgen index (FAI), insulin, dehydroepiandrosterone sulfate (DHEAS), Adione, and Adiol in 113 women of perimenopausal age (age range from 45 to 55 years) who had already experienced premenopausal menstrual decline (amenorrhea less than 2 years).Strong positive (r = 0.73) correlation between minimal bone density of maxillary sinus in women with level of DHEAS was detected. It is important to note, that the correlation between minimal density of the lower wall of frontal sinus is a weak positive (0.3). Therefore, it can be suggested that bone tissue of the maxillary sinus is more sensitive to changes in DHEAS.The study showed that the level of male steroids, in particular DHEAS, affected the state of bone tissue in participants older than 50 years of age.

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.
