- Аннотация: The association between the form (i.e. shape and size) of the bone nasal cavity (NC), soft-tissue nasal airways (NA), and paranasal sinuses as well as the potential effect of body size and composition on the aforementioned structures can be best assessed using large and well-documented samples of CT images of living individuals. However, to date, these relationships remain poorly descripted especially when considering soft tissues. To these ends, we developed a comprehensive protocol including volume and dimensions of theNC, volumes of theNA and paranasal sinuses, and some dimensions of the neckmusculature which is usually visible in head and neck CT images. The latter was used as a proxy for the degree of muscularity of an individual. A pilot study based on that protocol was carried out on a sample including 14 adult individuals fromMoscow and an outer group of 5 adult individuals from Bordeaux. In the sample from Moscow, the muscle thickness at the atlas was moderately or weakly positively correlated with all NC/NA volumes and dimensions and, surprisingly, strongly negatively correlated with the length of the NC. It was also highly positively correlated with the volume of the frontal sinuses. Volumes of the lower two thirds (i.e. excluding the ethmoid labyrinth) of the NC and NA were weakly correlated, confirming previous results byHeuzé (2018). NC and NA volumes were strongly cor- related with NC height, and moderately correlated with its width. However there was no correlations between either NC or NA volume and NC length. The volumes of the sphenoid and maxillary sinuses were rather independent from other variables (the latter only showed moderate correlations with height and length of the NC) while the frontal sinus volume displayed moderate correlations with the volume of theNC, neckmuscle thickness andNCheight.These associations probably reflect the well-known relationships of the frontal sinus volume with the size and robusticity of the skull. Interestingly, when the French individuals of both sexes were added to the sample, the resulting correlation matrix was similar but not identical to the matrix of the Russian sample alone (Mantel test 0.7, p = 0.0002) which points towards the presence of marked inter-population differences and sexual dimorphism in the studied variables.
