The study of paranasal sinuses is complicated by the presence of recesses that are sometimes interpreted as sinus vestiges or mistaken for true sinuses. This study compares the distribution of bone cells along osseous walls of maxillary sinuses (MS) versus recesses (MR) at birth. Serially sectioned slides of three primates that form MSs in adults (2 tamarins; 1 marmoset) and one species that forms an MR in adults (squirrel monkey: Saimiri sciureus ) were examined regarding osteoclast and osteoblast distribution along the boundaries of the MS or MR. Bone cell distribution suggested a similar trend among species with an MS, with osteoclast‐mediated expansion at the superior and inferior boundaries of the MS and more variable medial and lateral expansion. Saimiri was similar in the superior, inferior, and inferomedial distribution of osteoclasts along inner surfaces of bone bordering the MR. However, the MR was not completely enclosed in bone superolaterally, and had less inferior excavation compared to the MS of newborn callitrichids. Results suggest that perinatal MR formation in Saimiri may bear some early resemblance to MS formation, characterized by a lesser magnitude of osteoclastic activity or earlier cessation of resorption. Further work is needed to determine whether differing facial morphology or other factors determine the extent to which these spaces excavate the body of the maxillary bone.
