The aim of our study was to create a database of the most informative diagnostic criteria for predicting the treatment results for various odontogenic maxillary sinusitis (OMS) forms using automated computer software. Materials and methods: In order to select and assess the most informative diagnostic criteria for predicting the treatment results for various OMS forms, the total of 9 subject matter experts (SME) were included into the problem commission on the specialty “Dentistry”. Results: After calculating the data obtained according to the method of Yana V. Nosova, the working group experts’ level of competency was M = 0. 90. This confirmed the group’s qualification, which further led to the approval of scoring coefficients, depending on the degree of a particular index importance. The basic and minor parameters in the subjective, objective, introscopic and laboratory data of OMS patients were identified. Conclusions: The developed database of diagnostic criteria has formed the basis of an automated computer software for predicting the course and individualizing the patients’ treatment in odontogenic maxillary sinusitis.

The article publishes the results of treatment of 27 patients with fractures of the face middle area, of which 14 used standard titanium mini-plates to reposition the fragments, and 13 – individual 3D simulated titanium mini-plates / grids. Before and after treatment, its effectiveness was assessed by the values of the displacements of bone fragments and the index of the visual-analog scale, which allows determining the functional and cosmetic effect of the surgery. It was found that the use of individual 3D simulated titanium mini-plates / grids allowed obtaining in 85 % of patients displacements not exceeding 3 mm. In 72 % of patients in whom standard titanium mini-plates were used, the displacement after surgery was 3.1–6 mm, which is significantly greater than in the group with individual modeling of structures. On the 7th day after surgery in the first group (treatment with standard mini-plates), the index on the visual-analog scale was 11 (7; 13), which was significantly (p=0.00147) less than before surgery. In the second group (treatment using individual 3D simulated titanium mini-plates / grids) the index on the visual analog scale was 4 (6; 8) points, which was significantly (Z=3.3; p=0.00098) less than before surgery. Comparison of the visual-analog scale of the first and second groups on the 7th day after surgery revealed the presence of significant (U=2.47; p=0.013) differences. The obtained results testify to the greater efficiency of individual 3D modeled titanium mini-plates / grids in comparison with standard titanium mini-plates. The object of the research: fractures of the middle area of the face. Comparison of the visual-analog scale of the first and second groups on the 7th day after surgery revealed the presence of significant (U=2.47; p=0.013) differences. Investigated problem: the comparative evaluation of the effectiveness of the middle area of the face fractures treatment using individual 3D simulated titanium mini-plates / grids and standard titanium mini-plates. The main scientific results: Optimizing the treatment of fractures of the face middle area will help to achieve good cosmetic and functional results. The area of practical use of the research results: Department of Surgical Dentistry and Maxillofacial Surgery. Innovative technological product: The proposed technique using individual 3D-simulated titanium miniplates will help to optimize the treatment of patients with traumatic fractures of the face middle area. Scope of the innovative technological product: Clinical practice.

Background. Fractures of the bones of the facial skeleton, in particular the midface area, are one of the most frequent reasons for patients to apply to maxillofacial inpatient care, not only in Ukraine but also abroad. Along with more modern treatment technologies (osteosynthesis using titanium miniplates and minigrid for fixation bone fragments), methods of repositioning of fragments with subsequent tamponade of the maxillary sinus with iodoform tampon and without tamponade and fixation of fragments are used. A certain group of patients is treated conservatively, which is associated with their reluctance to undergo surgery, minimal displacement of fragments or minimal cosmetic and functional impairments. The purpose of the study. Comparative evaluation of the results of treatment of patients with fractures of the midface area by repositioning the fragments of the zygomatic-orbital complex without fixating the fragments and their subsequent fixation by tamponade of the maxillary sinus with iodoform tampon. Object and methods of research. The comparison was made of the results of treatment of 70 patients with fractures of the midface area, among which 13 patients were treated by the method of repositioning fragments of the zygomatic-orbital complex (ZOC) without fixation and without maxillary sinus tamponade, 29 patients underwent repositioning of ZOC fragments with subsequent fixation of fragments with iodoform tampon – the tamponade of the maxillary sinus was performed on the affected side. For comparison, the results of conservative treatment of 28 patients with fractures of the midface area were used. Results. It was found that the reliable (χ2=11.43; p<0.05) majority of patients (64%) sought treatment within 0-3 days after injury. 83-89% of patients who underwent repositioning of the fragments had fresh small-fragment fractures. The reliable (χ2=11.43; p<0.05) majority of them simultaneously had 3-4 sites of bone fractures of the midfacearea, hemosinus of varying degrees and paresthesia in the infraorbital area. In the majority of patients who underwent repositioning of bone fragments with and without tamponade (85% and 93%, respectively), the final displacements ranged from 3.1 to 6 mm. In patients treated conservatively, in most cases (93%) the displacements were greater than 3.1 mm, which remained after treatment. Conclusion. In the majority of patients treated with the studied methods, in the long term, the displacement of bone fragments remained, which had functional and cosmetic consequences. In all studied groups, a certain cosmetic effect was achieved over time, as evidenced by a reliable (χ2=160.9; p=0.00000) decrease in the indicator by the visual analogue scale .
