AGE AND GENDER CHARACTERISTICS OF THE AREA OF THE CROSS-SECTION OF THE TYMPANIC SEGMENT AND THE SECOND GENU ANGLE OF THE FACIAL CANAL
Abstract
The purpose of the study. To study the cross-sectional area of the tympanic segment of the facial canal near the second genu, as well as to measure the angle of the second genu in people of different ages with the determination of the gender characteristics of these parameters.
Material and methods. 133 head tomograms of people of different ages were studied. The tomograms were divided into age groups: 7-12 years old, 13-16 years old, 17-21 years old, 22-35 years old, 36-60 years old and 61-74 years old. In each group, male and female subgroups were distinguished.
Results and discussion. Comparing separate age groups of men and women, it was found that significant differences are observed in women. So, when comparing the age groups of 22-35 years and 36-60 years, significant differences were noted in the size of the angle of the second genu both on the left (0.001) and on the right (0.008). Comparison of groups aged 22-35 years and 61-74 years old revealed the reliability of the indicators of the cross-sectional area on the right (0.008); 13-16 years old and 36-60 years old – the angle of the second genu on the left (0.009); 17-21 years old and 36-60 years old – indicators of the angle of the second genu on the right (0.049) and the cross-sectional area on the left (0.014); 17-21 years and 36-60 years – cross-sectional area on the left (0.012), 36-60 years and 61-74 years of the second genu angle on the right (0.003).
Conclusion. As a result of the above, it can be concluded that the cross-sectional area of the tympanic segment increases from the age of 7 and becomes the largest by 35 years of age, then gradually decreases. A similar picture was observed when comparing the angle of the second genu in different age groups. Considering the gender differences in both parameters, we found that significant differences are observed in women, both on the right and on the left.
