This investigation was aimed at the evaluation of the morphometric characteristics of the contralateral sides of the facial cranium in adult men and women, the evaluation of asymmetry manifestation degree and the detection of most frequent zones of its localization. The study was conducted on 180 crania (90--male, 90--female) of the adults of I and II mature age periods. To detect the asymmetry of the facial cranium, the original "fan" principle of morphometry was developed. This approach has shown the asymmetry in the area of localization of different "fans" ("superior", "inferior", "lateral"), i.e., in the different regions of the facial cranium. On the basis of the data obtained, it can be concluded that in order to identify the asymmetry of the facial 1 cranium and to estimate the asymmetry manifestation degree it is expedient to take into account the following parameters: the distance from a nasion point to a point on the lateral edge of apertura piriformis, from a nasion point to a frontomolare-temporale point, from a zygomaxillare point to a lateral point on naso-frontal suture, from a zygomaxillare point to a dacryon point, from a subspinale point to a nazomaxillare point and from a subspinale point to a lateral point on naso-frontal suture. As in the series of the male crania asymmetry of the facial cranium was significantly more expressed than in the series of female ones, it is assumed to be associated with the different tone of mimic muscles. |
