The structural features of the paranasal sinuses play a key role in the development of pathological processes within them. The aim of our study was to examine the variations in the anatomical structure of the maxillary sinus based on Multispiral Computed Tomography (MSCT) data. MATERIAL AND METHODS: The study involved 400 individuals aged 18 to 44 years, both male and female. During the study, attention was given to the following topographical and structural indicators: linear dimensions of the maxillary sinus2. The position relative to the nasal cavity, which is also important for reconstructive surgeries and cosmetic procedures. For planning surgical interventions in plastic surgery, the location and prevalence in height of the sinuses were also parameters studied in this work; pneumatization features, which deserve special attention from both researchers and practicing physicians; the average volume, wall thickness, and density, measured as key structural indicators of the sinus. Additionally, these data can indirectly indicate potential risks of complications; the study also determined the dependence of the calculated indicators on gender and age. RESULTS AND DISCUSSION: The maximum average sinus volume was found in men aged 60-74 years and women aged 18-44 years. This measure was 19.05±2.33 x10⁻⁶m³ and 19.3±2.9 x10⁻⁶m³, respectively. The minimum average volume was observed in men aged 45-59 years, where it was 13.02±2.3 x10⁻⁶m³. In the corresponding age group of women, the minimum average volume was slightly higher, at 11.9±2.1 x10⁻⁶m³. In other groups studied, the average volume values were intermediate between the maximum and minimum values. CONCLUSIONS: The results of this study provide insights into the variations in the structure of the human maxillary sinus based on MSCT data. The average sinus volume indicators were calculated, with a maximum of 19.05±2.33 x10⁻⁶m³ and a minimum of 11.9±2.1 x10⁻⁶m³. Additionally, the study identified features of the topographical location of the maxillary sinuses in relation to the external nose.
