Summary:

Objective: to determine the morphometric parameters of the auricle and their relationships in dolichocephalic girls. Material and methods. The work used 86 photographs of the right auricle of dolichocephalic girls. 13 morphometric parameters were determined, including: the height of the auricle, the position of the apex of the tragus, the bottom of the intertragal notch, the most protruding anterior edge of the helix and the posterior one-at the level of the apex of the tragus, the height of the ear lobe and the area of the selected sectors. Correlation and regression analyses were conducted. Results. The paper presents the average values of morphometric indices of the auricle of dolichocephalic girls and 27 formulas of simple and complex regression characterizing the identified relationships between the indices. The strongest relationship was established between the position of the apex of the tragus and the bottom of the intertragal notch (r=0.77), the size of the area of the outer part of the auricle and the position of the posterior edge of the helix at the level of the tragus (r=0.79). Conclusion. A database of morphometric and mathematical indicators describing the structure of the auricle of dolichocephalic girls and their relationships has been created. Statistically significant relationships between auricle parameters of different strengths have been identified, which formed the basis of regression equations that make it possible to predict the value of one parameter based on another.
