Objective:
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.
Patients And Methods:
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:
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.
Conclusion:
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.
