Studying the characteristics X-ray pictures of the maxillary sinuses more than 350 patients with odontogenic diseases of the maxillary sinuses and no odontogenic of origin, as well as images of the maxillary sinuses in normal. We used data of orthopantomography, panoramic zonography middle and upper areas of the face, radiography of the paranasal sinuses, cone-beam and multislice computed tomography. Diseases of the maxillary sinuses characterized by a variety of origin and X-ray manifestations, which makes the complexity of the diagnosis. In this regard, the necessary knowledge of X-ray skialogicheskih features of pathological processes and the efficiency of X-ray techniques to objective detect not only the changes in the sinuses, but the factors causing the them. Multi -projection X-ray computed tomography examination of the maxillary sinus and alveolar process of the maxilla is a reliable method of assessing the state of the maxillary sinuses and the differentiation of the origin of maxillary sinusitis. Common dental X-ray techniques are limited diagnostic capabilities of assessing the state of the mucous membrane and the walls of the maxillary sinuses, which must be considered when interpreting the image.
