DIAMETER OF DIFFERENT AREAS OF THE FACIAL CANAL BASED ON THE RESULTS OF CT STUDIES

Abstract

Purpose is to determine the diameter of the various sections of the facial canal, taking into account the cranial index and sexdifferences on tomograms of the human skull.Material and methods. The material for the study was 133 tomograms. The studies were performed in sagittal, axial and coronal projections with the identification of the facial canal. All skulls were divided into brachiocrans, dolichocranes and mesocranes according to the cranial index. In all groups, male and female skulls were identified. All digital data were recorded and subjected to statistical processing by variational and dispersion methods using the IBM Statistics SPSS-26 program.Results and discussion. Thus, in male brachiocranes, both on the right and on the left, the diameter of the inlet is somewhat larger compared to the outlet, the stylomastoid foramen. These indicators are the smallest in men with a mesocranial type of skull. In women, these indicators are somewhat less pronounced than in men and do not have a significant difference in turtles of different shapes. However, it can be seen that the narrower part is the labyrinth segment.Conclusions. Analysis of the results showed that the diameter of the facial canal has a larger diameter in the inlet, the smallest size in the region of the labyrinth segment. In men, the canal is slightly wider in diameter than in women. Differences in diameter in all studied areas of the facial canal in skulls with different cranial indices, as well as on the left and right, were not observed.
