Background. Asymmetry is a fundamental characteristic of the human body, reflecting the non-identical nature of the right and left halves of the human body due to differences in anatomical structure, topography, innervation, trophism and functional loads, among other factors. Objective. To investigate the frequency of physiological asymmetry in various facial structures and areas in males, and to elucidate the characteristics of their age-related dynamics. Methods. A total of 50 males (divided into five age groups with 10 individuals each according to age periodization) were examined. Symmetry was visually assessed for facial width, eye size and shape, eyebrows, eyelids, nasolabial folds, corners of the mouth, smile, nose position, nostril size and shape, ear size, shape and position, and the alignment of the midline between the central incisors of the upper and lower jaws. Results. It was found that in childhood and adolescence 30% of boys exhibited no visual signs of facial asymmetry, while in young adulthood this figure dropped to 10%. In adulthood, asymmetry was detected in all examined men. Asymmetry in one parameter was found in 40% of children, 50% of adolescents, 20% of young men, 40% of men in the first period of adulthood, and 30% of men in the second period of adulthood. Asymmetry in multiple parameters was observed in 30% of children, 20% of adolescents, 70% of young men, 60% of men in the first period of adulthood, and 70% of men in the second period of adulthood. Conclusion. Smile asymmetry was found in all age groups and was the most frequently observed parameter among all studied indices. Ear asymmetry was the least frequently observed and detected only in men of adulthood.
