Abstract

The study of the anatomical structure of the human frontal sinus is highly important for modern fundamental and clinical medicine in terms of surgical approaches to the paranasal sinuses and cranial cavity, as well as due to the need to restore it after surgeries. This research was performed using the skulls from our university’s collection and their radiographs in the frontal and lateral projections. The study aimed to discover a significant correlation between the shape and size of the supraorbital margin of the frontal bone and the frontal sinus. Using sufficient cranial and radiological material, we showed a significant correlation between the structural features of the frontal sinus and the spatial location of the supraorbital margin in middle-aged people. The study was performed using the method of digital photometry: quantitative characteristics and spatial location of the supraorbital margin were determined, relative to the standard parameters of the orbit. Further, these parameters were evaluated and a classification was developed using the curvature index (CI) introduced by the authors. Three variants of spatial location of the supraorbital margin were singled out: CI less than 30 – minor curvature, CI 30–45 – average curvature, and CI more than 45 – large curvature. Having studied the skulls and their radiographs, we found that the greater the curvature of the supraorbital margin, the more pronounced the frontal sinus.
