ABSTRACT
The authors carried out a morphometric study using 200 computer-aided tomograms of the nasal cavity and paranasal sinuses of men and 100 documented macerated male skulls sawed in sagittal plane. The new index of the nasal cavity configuration that characterizes the ratio of the nasal cavity width to its height was developed. The index calculation was made in coronal plane transversing the ethmoid processes of inferior nasal turbinates. According to the nasal cavity configuration, all the material studied was divided into several groups: leptocavital – under 49.9, mesocavital –50.0 to 56.5 and platycavital – above 56.6. The authors distinguished the typical features of intranasal structures depending on the nasal cavity form. In case of increasing of the nasal cavity configuration index there is an increase of general nasal passage width in the anterior, the thickness of the front end of the middle turbinate, the decrease of general nasal passage width and nasal cavity height in its anterior part. The above-described typical features of the nasal cavity anatomy can affect the aerodynamics of the nasal cavity and paranasal sinuses.
