Background. Search of noninvasive methods for studying anatomical objects by a considerable amount of examples is one of the topical directions of modern science. The research is aimed at development of a method of paranasal sinuses 3D-models building with opportunity of their measurement and comparison.
Materials and methods. The method of cranial cavities 3D-models building comprised the usage of SCT data. It allows to study cavities’ form and size. For this purpose the authors made a web-application that helps to get information about inner contour of sinus walls, save it and load into MeshLab v. 1.3.2. (Visual Computing Lab, 2012, Italy). After texture mapping the sinus cavity may be visualized and its parameters can be measured with the Measuring tool in different directions between any points.
Results. The method allows to study the features of one sinus on the one hand and cranial growth and development trends on the other hand. Rhino/analyzer application enables to compare the shape and sizes of two sinuses. It can be used in clinical prac-tice to increase accuracy of surgeries, especially reconstructive and endoscopic ones. Further development of software would make it possible to use this method in more detail study of cranial cavities’ forms and sizes.
