SOME MORPHOMETRIC PARAMETERS OF THE FACIAL CANAL IN MEN AND WOMEN WITH DIFFERENT SKULL SHAPES

Abstract

The purpose of this study was to measure the length of the labyrinth and mastoid (vertical) segments of the facial canal in men and women of the brachio-, dolicho-, and mesocranial skull types.
The material for the study was 133 tomograms taken from the archives of the Department of Radiation Diagnostics and Radiation Therapy of the Azerbaijan Medical University. The studies were performed in sagittal, axial and coronal projections with the identification of the facial canal. All skulls according to the cranial index were divided into brachiocranes (80,0 and up), dolichocranes (74.9 and below) and mesocranes (75,0-79,9). we also conditionally divided the facial canal into three parts: labyrinthine, tympanic and mastoid (or vertical). The length of the labyrinth segment was measured - the distance from the entrance to the facial canal to the middle of the first knee - and the length of the mastoid or vertical segment - the distance from the middle of the second knee to the stylomastoid foramen.
Results of research. Statistical analysis according to the Kruskal Wallis test showed that in brachiocraniums when comparing the length of the labyrinth part in men and women both on the right and on the left (in men on the right - 2.29±0.05, on the left - 2.30±0.04; in Women, respectively - 2.45±0.04 and 2.42±0.03) have significant differences (right - 0.013, left - 0.006). The analysis of these indicators by the Student-Bonferroni method also confirmed the above. Reliable differences were observed in women and when comparing all three groups of skulls with different cranial indices (right – 0.013; left – 0.012). So, in women with brachiocranium, this indicator is on the right - 2.45±0.04, on the left - 2.42±0.03; at dolichocranes respectively - 2.33±0.04 and 2.34±0.03; in mesocranes,
respectively - 2.27±0.03 and 2.29±0.02. In men, no significant differences were observed when comparing brachiocraniums, dolihocraniums, and mesocraniums. When comparing groups according to the Mann-Whitney method, significant differences (0.036) were observed between brachiocranes (7.38±0.22) and dolichocranes (8.08±0.22) in the length of the mastoid segment only in men. When comparing the other groups with the application of various methods of statistical processing, no reliable results were obtained.
Conclusion. The obtained data on measuring the length of the segments showed that the length of the labyrinthine segment to the beginning of the knee of the facial canal is longer in brachiocephalic women than in men. In brachiocephalic women.. The length of the facial canal from the place of transition of the first knee to the stylomastoid foramen was greater in men with dolihocrans on the right compared to other forms of skulls.
