Eskimo craniofacial morphology, cold stress and the maxillary sinus

A determination of the capacity of the maxillary sinus was made for eight Eskimo populations, one Mongolian population and one American white population. Statistical analyses reveal strong and significant correlations of the mean temperature of the coldest month where these populations live with differences in mean maxillary sinus volume (MSV) values. Results indicate that maxillary sinus volume in Eskimo populations decreases in colder areas....
