Assessment of Measurement Uncertainty of the Uncinated Process and Middle Nasal Concha in Spiral Computed Tomography Data

Ostiomeatal complex is a key anatomical zone that provides physiological functioning of the paranasal sinuses. It is here that such important functions as drainage and ventilation of paranasal sinuses occur. Consequently, the narrowing of this area leads to significant changes in paranasal sinuses with the development of acute and chronic rhinosinusitis. Today, computed tomography is the "gold standard" for diagnosing rhinosinusitis. The purpose of our research was to optimize the study of tomographic images of the anatomical components of the ostiomeatal complex (uncinate process, nasal concha) according to computed tomography analysis. The study comprises the assessment of Spiral computed tomograms (coronary sections). To measure uncertainty, the maximum and minimum value of each indicator was calculated. Thus, in order to optimize the study of the anatomy of the ostiomeatal complex components according to the spiral computed tomography findings, it is reasonable to apply the method of calculating uncertainty.
