title: [Tomography of the maxillary sinus].
abstract: The maxillary sinuses were studied roentgenographically and tomographically in 108 patients (with intact sinuses) and in 16 anatomical preparations of the cranium. It has been established that the main features of the laminar picture of the maxillary sinuses can be determined by two main properties of tomography as a method: the possibility to lead the portions of the sinus osseous walls of greater-length as compared with conventional roentgenography out to the edge-forming zone due to oblique course of the ray beam, and vise versa, disappearance of outlines of these walls in those sections where they are considerably inclined in relation to the roentgen film plane. A description of the laminar roentgen-anatomical picture of the maxillary sinuses in naso-frontal, nasomental and lateral projections is presented. It is stresses that in each of these projections several main types of the laminar picture of the maxillary sinuses can be detected, characterizing different depth of sections.
