Analyzing the maxillary sinuses using 3D-modeling

Introduction. The study of the anatomy of the maxillary sinuses using computed tomography (CT) techniques is an important area of scientific research. The most developing technique that allows you to move from planar images to a picture that clearly represents the shape of the anatomical structure and topographic-anatomical relationships is 3D-modeling.

Purpose. Analyze the forms of the maxillary sinuses using 3D-modeling using the Autoplan APK.

Materials and methods. The primary analysis included 260 studies, from which 80 studies were subsequently selected. The studies were carried out on Aqulion 32 (Toshiba, Japan) and Revolution EVO 128 (GE, Russia) computed tomographs. MSCT was performed on patients aged 22 to 84 years. The average age of patients in the study group was 52.31±3.18 years. To stratify the patients of the study group by age groups, the age periodization scheme of the Institute of Age Physiology of the Russian Academy of Medical Sciences (1969) was used.

Results. The analysis of the shape of the maxillary sinuses showed that the trends in the prevalence of different types of their forms are almost the same, both in the general analysis of the shape of the maxillary sinuses in the study group, and in the isolated analysis of the right and left maxillary sinuses.

Conclusion. To conduct a full study of the shape of the maxillary sinuses allows only their three-dimensional modeling, it also allows you to move from linear dimensions to volumetric measurements by highlighting all the elements of the volumetric image that relate to the sinus cavity. The study of the shape of the maxillary sinuses is a modern problem with the lack of a unified approach to the process of segmentality and interpretation of the results. With regard to otorhinolaryngology, three-dimensional reconstructions of images semi-accepted on the basis of computed tomography are effective in assessing the choice of the type of surgery that is most acceptable in a particular patient.
