Earlier studies of the linear characteristics of the parameters of the skull demonstrate the lack of a unified point of view on this issue. The current level of development of practical medicine requires morphometric accuracy in determining the shapes, spatial location and dimensional characteristics of the craniofacial complex parameters. The search for the most informative features using new technical and statistical methods is one of the current trends in modern craniology. The purpose of the study is to identify the variability of the morphometric linear parameters of the facial section of the skull, taking into account the craniological type. The article presents the morphometric characteristics of the linear parameters of the facial section of the skull of persons of mature age of both sexes. The work was carried out taking into account the craniological type. The presence of sexual dimorphism with prevalence of indicators on male preparations was found for the length and width parameters of the facial section of the skull only on mesocranic type skulls, for the parameters of the upper and middle depths of the facial section of the skull - only on mesocranic and dolichocranic type skulls. A sign of stability of indicators was established for indicators of the dents-alveolar part of the upper and lower jaw, the height of the lower jaw, the upper and middle depths of the facial section of the skull on preparations of the brachycranic type and the upper height of the facial section of the skull on preparations of the mesocranic type. Thus, the presence of sexual dimorphism with prevailing indicators on male preparations, depending on the type of skull, is proved.

We studied variant anatomy of the dentomaxillary (192) and dentomandibular segments (1040). We defined the ideal intraosseous needle injection site, the pattern of the spread of the fluid which is administered intraosseously from the site of injection. The use of an intraosseous needle injection site depends on the localization of the pathological focus.

We examined morphometric parameters of the bone tissue of 168 dentoalveolar segments that include maxillary incisors and canines regarding vertical midline. The area of dentoalveolar medial incisor segments was 1.81±0.14 cm(2); it did not differ significantly from the area of lateral incisor segments. The area of dentoalveolar segments including canines exceeded the corresponding figures in incisor segments. The thickness of the compact bone on the vestibular surface significantly increased from the cervical portion of the segment towards its base. The maximum thickness of the spongy bone on the vestibular surface was recorded in the apical part of canines dentition segments; the minimum thickness, in the middle portion of the dentoalveolar segments of lateral incisors.
