In order to test the hypothesis that variation in the maxillary sinus volume (MSV) of anthropoid primates is related to skull architecture, a mixed sex sample of adult primate crania covering Hominoidea, Cercopithecoidea and Ceboidea was examined using CT scans. MSV was regressed against basicranial length, using reduced major axis analysis. 2 distinct scaling patterns emerged: while a large MSV seems to be a primitive condition of Anthropoidea, it is clearly reduced in Cercopithecoidea. Although some correlations exist between MSV and different indices of the facial skeleton, they are relatively weak and differed among the 3 groups. A full appreciation of epigenetic factors and the relation of the paranasal sinuses to different cranial components is necessary to highlight the biological role of skull pneumatization.
