The paper presents the results of a clinical observation of a 6-year-old female patient, who was admitted to the department of maxillofacial surgery of a multidisciplinary hospital under the compulsory health insurance system with a rare disease of the bone tissue of the lower jaw – desmoplastic fibroma. Desmoplastic fibroma of bone tissue (aggressive fibromatosis, desmoid fibroma) is a rare, locally aggressive, benign tumor localized in bone tissue, it is a mesenchymal fibroproliferative tumor with locally destructive growth, accounting for less than 0.03% of all human tumors. According to the literature, desmoplastic fibroma has a recurrence rate of 37% to 72%, resection of the affected bone is the preferred therapy, and, ideally, resection should be a single resection block. Wide excision is the method of choice for treating operable desmoid tumors in children. The article presents a dynamic observation within 1 year after surgical treatment. The article presents the clinical, radiological and computed tomographic picture of the disease and the results of instrumental and histological examination of a rare oncostomatological pathology. Purpose: clinical, radiological, 3D computed tomography observation of a child with desmoplastic fibroma of the lower jaw. Materials and methods: the results of a clinical examination, instrumental methods of X-ray diagnostics, stages of surgical treatment, a histological report and photographs of the patient's appearance are presented. Conclusion: Given the high regenerative capacity of bone tissue in children, it is necessary to perform surgical treatment of benign neoplasms by the type of marginal resection, that is, by the organ-preserving type, and to conduct dispensary observation of the patient during the first year.

The objective of the study is to evaluate the condition of the alveolar part of the upper jaw and the part of the mandible according to X-ray studies in postmenopausal women before and after surgical treatment of the atrophy of jaw bone tissue using osteoplastic material and an ossein-hydroxyapatite compound. Materials and methods: There were observed 24 women in the postmenopausal period, aged from 51 to 58 years, with atrophy of the alveolar process of the upper jaw and the part of the lower jaw who were surgically treated. Results of the study. On the basis of the obtained results of the X-ray examination, we can assume that the developed by us technique of surgical treatment of atrophy of the alveolar process of the upper jaw and the part of the lower jaw by the use of bone material of animal origin in combination with the ossein-hydroxyapatite compound allows us to intensify bone tissue regeneration processes, which further will contribute to the increase of the volume of bone tissue. Conclusions. The use of modern X-ray methods, in particular orthopantomography and cone-beam computerized tomography in the diagnosis and surgical treatment of atrophy of the alveolar process of the upper jaw and the part of the lower jaw, are highly informative, and also provide the possibility of work with a roentgenographic image in a digital format that allows a more detailed assessment of the area of surgical intervention before and after the treatment.

Traumatic injuries and fractures of the lower jaw are an urgent problem in maxillofacial surgery and traumatology. The strength of the bone tissue of the lower jaw has been studied on 90 lower jaws of adults. All jaws are systematized into three groups: with intact bite, partial and complete loss of teeth. To assess the architectonics of the bone tissue of the mandibular body, sagittal and frontal cuts were made in the molar region. It has been established that, in the case of a complete set of teeth, the ultimate strength of the bone tissue in the area of the incisors is 441.3 ± 32 MPa; in the area of premolars 411.9 ± 20 MPa; molars 431.3 ± 24 MPa; in the area of the base of the coronoid process 156.9 ± 14 MPa; in the area of the base of the condylar process 205.9 ± 19 MPa. To the greatest extent, with partial loss of teeth, the strength of bone tissue in the region of the molars and the angle of the lower jaw changes in Kennedy classes I and II. With the complete loss of teeth, the values of bone strength in the area of molars, angle and condylar process decreased by 22.5-27.7%, in the area of incisors by 6.7%. It was shown that with a full set of teeth, class II according to U. Lekholm and G. Zarb was most often observed - in 66.7% of cases, less often class I - in 16.7% and class III - in 13.3%, class IV was observed most rarely - in 3.3% of cases. With complete loss of teeth, the presence of mainly II and III classes is noted. It has been proven that the strength of the bone tissue of the lower jaw body decreases significantly with age with the loss of teeth in an adult, which is associated with significant changes in the quality of bone tissue.

The restoration processes of damaged or lost bone tissue are an important and topical issue of surgical dentistry and maxillofacial surgery today. According to statistics, diseases that are accompaning by destructive changes in bone tissue occupy one of the dominant places among the nosologies of MFA. Along with the use of updated methods of surgical technique, both before and now the problem of choice of bone-plastic material is relevant, because it is known that osteoplasty opens up great opportunities for complete rehabilitation of patients. The purpose of the study was to determine the effectiveness of our developed osteoplastic composition for the restoration of bone defects in dentistry. Materials and methods. X-ray computed tomography to determine bone density was performed in 26 patients with bone defect replacement "Kolapan-L" (group A), 28 people during augmentation of our proposed osteoplastic composition "Kolapan-L" + multipotent mesenchymal stromal cells + platelet-rich plasma) (group B), and 25 patients where the healing of the bone defect occurred spontaneously (group B). X-ray computed tomography was performed on a 16-slice spiral computed tomography Siemens Somatom Emotionc. Image processing was performed using the program "Dicom". Statistical processing of research results was carried out using conventional methods of variation statistics. Results and discussion. After 1 year of research, the average value of the bone density in patients of group B was probably higher: 1.5 times and 1.8 times relative to the corresponding data in groups A and B. At the same time, the minimum value of the bone density in patients of subgroups A and B was 1.5 times and 1.8 times lower than in persons of group B (p <0.01, p1 <0.01). At the same time, the maximum values of the bone density in patients of group B, where the augmentation of bone defects was performed using our proposed composition, were 1.4 times (p <0.01) and 1.8 times (p <0.05, p1 <0.01) higher than in group A, in the replacement of bone defects "Kolapan-L" and in group B, where the healing of the bone defect was spontaneous, respectively. It was found that in patients of group B after 12 months of studies, the average density of osteoregeneration was 1036.69±55.53 (HU), which was 1.5 times and 1.8 times more than in group A (p <0.01) and in group B patients (p <0.05, p1 <0.01) respectively. Conclusion. The use of tissue equivalent of bone tissue, proposed by us to replace a bone defect based on multipotent mesenchymal adipose tissue cells, contributed to the maximum increase in bone density, with a slightly lower effect of increasing bone density in the augmentation of bone defects

Morphological Diagnosis

Ameloblastoma is a benign, locally aggressive tumour, with an unicystic variant that is very difficult to be differentiated from odontogenic cysts, because of their similarity in the clinical manifestation and X-ray examination. The morphological similarities between these processes make for a more difficult histological diagnosis. We present a case of a 32-year old male, admitted in the Maxillofacial surgery clinic in a University hospital for surgical treatment, because of a swelling in the left mandibular vestibule. A cystic formation, histologically diagnosed as an epithelial one, is removed. Eight months later, the patient is admitted once again, with the same symptoms. The biopsy result from the second operation is a plexiform unicystic ameloblastoma. What is being discussed is the connection between the two pathological processes and the difficulties with giving the correct morphological diagnosis.

Introduction. Atrophy of the alveolar process of the upper jaw and part of the lower jaw is often observed after the tooth extraction. It is known that the atrophy of bone tissue is most likely observed in the first 12 months after the tooth extraction. According to the Koln classification, atrophy of the bone tissue of the jaws can be vertical, horizontal and combined. The aim of surgical treatment of jaw bone tissue atrophy is to increase the size in the area of alveolar process of the upper jaw and part of the lower jaw to further restoration of masticatory function, in particular with the use of dental implants. The aim of the study: to study the dynamics of wound healing in postmenopausal women with osteopenia after surgical treatment of jaw bone tissue atrophy using osteoplastic material and ossein-hydroxyapatite compound. Materials and methods of the study. There were observed 63 postmenopausal women with osteopenia, aged from 50 to 59 years, with atrophy of the maxillary and mandibular alveolar process, who were performed surgical treatment. During surgery, patients were divided into 3 groups: Group I – 23 patients with atrophy of the alveolar process of the upper jaw and part of the lower jaw with osteopenia, with the reduced bone tissue density, who were treated surgically for bone tissue atrophy using the method worked out by us. Group II – 23 patients with atrophy of the alveolar process of the upper jaw and part of the lower jaw with osteopenia, with the reduced bone density who were performed surgical treatment of atrophy of the jaw bone tissue using osteoplastic material of animal origin. Group III – 23 patients with atrophy of the alveolar process of the upper jaw and part of the lower jaw with the indices of bone tissue density within normal limits, who were performed surgical treatment of atrophy of the jaw bone tissue using osteoplastic material of animal origin. The results of the study. A total of 69 edentulous areas on the upper and lower jaws were examined after surgery for the treatment of jaw bone tissue atrophy. Examination of the postoperative wound was performed during the 3rd, 9th, and 14th day in the absence of complaints from patients during this period, as well as in the presence of signs of complications. Discussion of the results. According to the offered by us method of decortication of the bone tissue of the jaws, which was used to treat patients of group I, the blood supply to the postoperative area and infiltration of bone material with blood due to provoked by decortication of bone tissue bleeding, are improved. Impregnation of bone material with blood promotes angiogenesis in the postoperative area, increasing cellular activity during wound healing. It is known that due to the absence of sufficient blood supply, tissue necrosis occurs [8,9]. In patients of groups II and III the complete healing of the postoperative wound with primary tension took longer than in patients of group I. Also, in 3 patients of group II and in 1 patient of group III the wound dehiscence in the postoperative area was observed. Conclusions. As a result of the performed observations of wound healing after surgical treatment of jaw bone tissue atrophy in patients of groups I, II and III, the least complications were observed in patients of group I in the early postoperative period.

Introduction Medication-related osteonecrosis of the jaw (MRONJ) is a complication associated with the intake of osteomodifying agents (bisphosphonates, denosumab). At present, its frequency, according to various authors, may reach from one to 10 cases per 100 subjects. The literature describes the main factors in the pathogenesis of the disease. The prognostic signs of its development, which would allow timely diagnosis and prevention of the disease, remain not fully understood. Materials and methods The retrospective analysis was based on the results of a study of 52 patients with MRONJ who were treated at the Department for Maxillofacial Surgery at the Central City Hospital No. 23 in Yekaterinburg from January 2015 to December 2019 Multispiral computed tomography was used for visualization, quantitative and qualitative assessment of the jaw bone tissue. The optical density of the spongy substance was determined in Hounsfield units (HU) on the side opposite to the lesion. Results The analysis of the results of optical density showed that D1 bone type was not detected in any patient. We observed type D2 using CT in 5 cases in the central part of the lower jaw (9.61 %), in 9 cases in the central part of the upper jaw (17.3 %), as well as in the area of the angle of the lower jaw on 6 CT-scans (11.53 %). D3 and D4 bone types prevailed, D5 bone type was less common. The optical density of the structures under study was in the range from 229.8 ± 56.6 to 534.8 ± 155.4 HU. Thus, patients receiving osteomodifying therapy with bone types D3, D4, D5 are more at risk of developing MRONJ than patients with bone types D1 and D2. Conclusion It is advisable to include a mandatory MSCT with classification of bone types according to Misch and determine optical density of bone tissue in the examination protocols of such patients.

Relevance. Detection of maxillofacial pathomorphological changes in children with connective tissue dysplasia (CTD) allows identifying the nature and severity of disorders, as well as it serves the basis for selecting the best treatment options in view of the pathogenetic features. The purpose is to improve the diagnosis of periodontal diseases in children with CTD based on x-ray morphometric indices of the lower jaw and peripheral skeleton ultrasound osteodensitometry.Materials and methods. 92 children with varying CTD severity, and 43 healthy children, underwent cone-beam computed tomogram examination with a further analysis of their X-ray morphometric (quantitative, qualitative) values and the lower jaw optical density indices. Besides, the status of the peripheral skeleton bone tissue was also determined through quantitative ultrasonic densitometry.Results. Quantitative X-ray morphometric indices in healthy children and children with CTD revealed strong positive correlation with the Z-criterion of osteodensitometry, offering an objective reflection of the bone tissue status in the peripheral skeleton.Conclusion. CTD progression in children correlates with the bone structure destruction intensity in the maxillofacial area, an increase in chronic productive inflammation, a decrease in the bone density, bone tissue fibrous transformation, a decrease in the thickness of cortical, and fiber-dissociation in closing, plates, of the lower jaw, prevalence of mid- and fine-meshed bone pattern, disturbed spatial orientation and thinning of bone trabeculae, as well as the development of pathologies in the periodontium.

SummaryThe treatment of femoral head necrosis of adults is still rather problematic. Conservative treatment has been reported relatively unsuccessful and surgical treatment does not show convincing results either. The most effective seems to be a surgical treatment in early stages of the disease, however, the diagnosis still remains relatively complicated. For the late stages (2B and above) the most effective treatment option is represented by core decompression and vascular grafting. However, drilling and plombage (especially when using press-fit technique) seems to be successful, although not excellent. The authors describe their own method of drilling and plombage of the necrotic zone of the femoral head in 41 patients with X-ray detected necrotic changes of the femoral head. The pain measured by VAS was seen to decrease after surgery in all patients significantly. The Jacobs score was also observed to have increased (from fair to good outcome). We have not observed any large femoral head collapse after surgery, moreover, in some cases an improvement of the round shape of the femoral head was seen. It is important to mention that in all cases femoral heads with existing necrotic changes (flattening or collapse) were treated. Although the clinical improvement after surgery was not significantly high, the method we describe is a safe and simple method of diminishing pain in attempt to prepare the femoral head for further treatment in a future, without significant restriction of the indication due to necrosis (osteochondroplasty, resurfacing, THR).
