Asymmetry of the facial skeleton in Negroid skulls

: Measurements of 18 bilateral signs were carried out in 94 Negroid skulls. All parts of the facial skull are clearly asymmetrical, if regarded separately, while the summary sizes of the left and right halves of the facial skull are equal. In the upper part of the face the most asymmetrical parameters are the width of the bridge of the nose, width of the nose, and width of the palate, while the least asymmetrical are the height of the orbit and palate and length of the palate. In the mandibular part the greatest asymmetry was observed in the thickness and height of the mandibular corpus and height of the mandibular branches. The resultant combination of symmetry of the total sizes of both sides of the facial skull and asymmetry of individual parts is interpreted as an indication of the compensatory changeability of bilateral signs of the facial skull. The results are similar to data on the asymmetry of the facial skull of Mongoloid, Europeoid, and the intermediate skulls.
