title: [Symmetry and asymmetry of the orbital opening in Bulgarians].
abstract: The authors examined 412 skulls of grown up individuals of male sex and 15 dimensions were measured for aditus orbitae. The data were prepared biostaticaly both for the most important six and for the orbital index amd orbital entrance. The dimensions showed equal size at both sides in considerable, but various for the single numbers of skulls (1/5 up to over 1/3). In the majority of the remaining skulls the absolute differences were small in favour of the one or the other side (1--2 mm). The width of the entrance was in most cases (63%) larger in the right with mean value of the differences of 1,72 mm, but the height-on the left of the average with 1,41 mm. Hamachonchia was encountered more frequiently on the right, but hypoikonchia-on the left. The dimensions, which passed through the orbital entrance transversly (three dimensions) and obliquely (one dimension) had larger values more frequently on the right.
