The use of cephalometric analysis of lateral teleroentgenograms allows orthodontists, maxillofacial surgeons and other related specialists to organize a patient's treatment plan. However, for the full application of this method, it is necessary to determine in advance which indicators for it can be considered the norm, and which are already a pathology. The purpose of the study is to establish the peculiarities of cephalometric parameters according to the COGS method, related to the profile of the soft tissues of the face, in Ukrainian young men and young women with an orthognathic bite with different facial types. 46 young men and 72 young women who belonged to the residents of Ukraine of the Caucasian race in three generations and had an orthognathic bite were subjected to cephalometry according to the COGS method of indicators related to the profile of the soft tissues of the face. The face type was determined according to Garson's morphological index. Statistical processing of the obtained results was carried out in the license package "Statistica 6.0" using non-parametric estimation methods. Among Ukrainian young women with different types of faces, the following reliable or trends of differences in teleroentgenometric indicators related to the profile of soft tissues of the face according to the COGS method were established: young women with a very wide face have smaller values of the Gl'-Sn-Pog' angle and the Sn-Gn'/H-Gn' ratio (compared to the middle and narrow faces) and the angle Cotg-Sn-Ls and the distance Ls-(Sn-Pog') (compared to the middle face); young women with a wide face have larger values of the Ls-(Sn-Pog') distance and smaller values of the Stms-I distance (compared to the average face type); women with a narrow face have larger values of the Gl'-Sn distance and the Gl'-Sn/Sn-Me' ratio (compared to the medium face), the Sn-Gn'/H-Gn' ratio (compared to the wide face) and smaller values of the distance Sm-(Li-Pog') (compared to the wide face). Among Ukrainian young men with different types of faces, the following reliable or trends of differences in teleroentgenometric indicators related to the profile of soft tissues of the face according to the COGS method were established: representatives with a very wide face have larger values of the Gl'-Pog' distance (compared to an average face ) and smaller values of Sn-Gn'/H-Gn' ratio and Stms-I distance (compared to the average face); representatives with a wide face have larger values of the Sn-Stms/Stmi-Me ratio (compared to the average face) and smaller values of the Gl'-Sn/Sn-Me' ratio (compared to the average face); representatives with a narrow face have larger values of the Gl'-Sn/Sn-Me' ratio (compared to very wide and wide faces). Minor manifestations of sexual dimorphism of cephalometric parameters determined by the COGS method related to the profile of the soft tissues of the face were also established between young men and young women with different facial types.
