Comparative Characteristics of the Areas of the Auricle Sectors in Young Men with Different Head Shapes

As reported in the scientific literature, data on the correlations between the shape and size of the auricle and other anatomical structures of the human body are very limited. There are no data on the relationship between the auricle and the shape of the head. The aim of the study was to determine the sizes of the auricle sectors and their correlations with the shape of the head. Material and methods. The study involved young men (n=401) aged 18-21 years. The shape of the head was determined by cephalometry. The right auricle was studied on digital images. The authors determined the area of individual sectors and their percentage ratio and analysed a linear correlation. The dynamics of the relationship between sectors in each group and between groups was studied in accordance with the shape of the head. Results. The sizes of the auricle sectors and their percentage ratio were detected. Correlation links between the sectors, the dynamics of the relationships between the sectors within one group and between the groups by head shape were revealed. Mobile and permanent sectors and dependence of their relative sizes on the head shape were identified. The relationship between the sizes of the sectors and the head shape was demonstrated. Conclusion. The areas of the auricle sectors increase from S1 to S4 regardless of the head shape. In the dolichocephalic group, all sizes have the largest absolute values, in mesocephalics - average, in brachycephalics - the smallest. The ratio of the S1 sector area to the area of other sectors are maximum in the dolichocephalic group. The ratios of the S2/S4 and S3/S4 sectors areas do not depend on the head shape and absolute values of the parameters, and are the same in all groups.
