Annotation. The aim of the study is to compare the data obtained from the cutting of the jawbone in the maxillary sinus and the measurements obtained during the study of CBCT data. CBCT has been found to be sufficiently accurate to assess the anatomical topographic features of the maxillary sinus structure, with high research reliability. The accuracy of CBCT is comparable to that of the skeletal skull, making CBCT a reliable tool for studying maxillary sinus anatomy. Materials and methods. 48 certified skulls were studied. According to CBCT data, a three-dimensional model was constructed for each maxillary sinus by direct and indirect methods. To measure the parameters on the skull, a barbell rod was used with a follow-up check. Results. The corresponding metric characteristics are obtained: the volume of the sinus varies from 8.30 ± 1.48 cm3 to 41.92 ± 0.94 cm3, the tip of the anterior root of 1.7 teeth was from the bottom of the sinus, on average, by 4.86 ± 0.18 mm, 2.6 teeth – 4.04 ± 0.72 mm; which must be taken into account when performing interventions. Conclusions. The combination of CBCT and direct analysis provides the most complete understanding of the structure and variations of the structure of the sinus structure.
