“…Cyst-like jaw lesions varying in shape and size, surrounded by a thin osteosclerotic area, and potentially containing randomly located tooth germs, are common x-ray findings in patients with cherubism. Alteration of tooth germ development is a typical feature of cherubism [15]. Tooth germ malposition and crowding or lack of tooth germs have been observed in the disease.…”

This is an initiative study. Cherubism as a form of fibrous dysplasia of jaw bones is a congenital hereditary abnormality of osseous tissue maturation. Although the disease requires mostly maxillofacial surgery and orthodontic care, patients also have to be consulted by an ophthalmologist. The purpose of this study was to share our experience in the diagnostic assessment and treatment of cherubism, a rare form of fibrous dysplasia that is commonly misdiagnosed, which results in inadequate treatment and may lead to serious ocular complications. We present our experience of diagnostic assessment and treatment of four patients with cherubism for one to twenty years. The diagnosis of cherubism became evident after histological study of the material excised during surgery, because postoperative histology showed that changes were not cancerous (adamantinoma), but dysplastic. In addition, new foci developed or old foci recurred some time after surgery. Consequently, true jaw tumors must be correctly differentiated from dental cysts and from dysplastic bone lesions. Patients were followed up once every 6 months. Over the period of follow-up, ocular involvement was observed in the woman who had been diagnosed in childhood with congenital mixed astigmatism. Given our observations, one may make a conclusion that cherubism, a rare form of fibrous dysplasia, is a hereditary or familial disorder, and regresses after completion of puberty and puberty-related changes in hormonal milieu. Timely orthodontic care (and, if required, maxillofacial surgery care) will facilitate preventing the progression of the disease and its ophthalmological consequences. Special attention of ophthalmologists should be paid to cherubism patients with maxillary lesions.

Introduction: Application of automated analysis currently occupies a leading position in every field of science and technology. The aim of our study was to provide a complex automatic determination of morphological parameters for bone tissue in human paranasal sinuses. Materials and Methods: The study involved 50 patients aged 20 to 60, male and female without signs of inflammatory or other pathological processes in the paranasal sinuses (PNSs). Results: Bone density in a high-contrast image of the section can be determined by fluctuations in colour intensity. Before cleaning, the image is blurred using the Gaussian function. As a result of this operation, the images become less clear and small details merge. An algorithm known as the Connie Border Detector has found widespread use. The curves denoting the contours can run vertically, horizontally or diagonally at different angles. Detection of the direction of curves passing vertically and horizontally is not complicated, and for curves of the diagonal direction, the Sobel operator is used, with the vertical direction Gy and horizontal Gx as the value of the first derivative. Selection of areas of bone tissue requires the assessment of brightness gradient along the long side of the area. For clarity, this operation was shown graphically. Conclusion: Within the scope of this work, we have developed a method for an automatic comprehensive assessment of the morphological structure of the PNSs walls with the measurement of bone density and thickness.

“…Within otolaryngology, spiral computed tomography (CT) plays an integral role in the diagnosis and surgical planning of sinus lesions. However, Nechyporenko et al described the measurement uncertainty of spiral CT, as the images themselves are approximations generated by complex mathematical equations 4 . Physicians are not generally aware of how these mathematical processes produce a scan, yet we rely on imaging to navigate sinus anatomy intraoperatively in a space where small errors can lead to devastating consequences, including violating the skull base.…”
