Thing. A review of the literature devoted to the topical problem of maxillofacial surgery and surgical dentistry – methods of treating patients with mandibular fractures was carried out. The aim of the study is to review the materials of publications on the methods of treatment of patients with mandibular fractures. Methodology. The publications of domestic and foreign authors, considering methods of fixation of bone fragments in lower jaw fractures, have been studied. Results. Publications indicate that there are many treatments for mandibular fractures. Research results demonstrate the importance of bone stabilization for bone fusion. A common disadvantage of conservative and surgical methods of treatment is unstable fixation of bone fragments, which is the most common cause of delayed consolidation of a mandibular fracture. The presented studies show that bone osteosynthesis with metal plates is considered the most appropriate method for treating mandibular fractures. Conclusions. Splinting as a method of treating fractures of the lower jaw has a large number of disadvantages. A common disadvantage of methods for splinting the lower jaw is that these structures do not always provide anatomical reduction and stability for the entire period of consolidation or require mandatory intermaxillary fixation, the lower jaw is fixed in the central occlusion position, which is not a position of physiological rest, and leads to passive muscle tension. depriving them of active function. The main disadvantage of the methods of osteosynthesis using a suture and using wires is that it is difficult to achieve stable fixation of fragments using these techniques. Combined methods of fixation of bone fragments (use of a bone suture and dental splints) provide a stronger fixation of the fragments. In the past two decades, in the treatment of mandibular fractures, there has been an increase in the trend towards rigid or semi-rigid osteosynthesis using plates. The disadvantages of compression osteosynthesis is that significant compression can lead to ischemia and slow down the formation of callus. A common disadvantage of conservative and surgical methods of treatment is unstable fixation of bone fragments, which is the most common reason for their delayed consolidation. Bone osteosynthesis with metal plates is considered a more progressive method of treating mandibular fractures.

The aim of this study was to study the possibility of the lower jaw exoskeleton as a means of treating its fractures. The analysis took into account the ability of the extrafocal osteosynthesis apparatus to maintain the spatial orientation of bone fragments under load. For this, the apparatus was analyzed by the finite element method on 3D models and a study was carried out in a special stand on the bones of the human lower jaw. As a result of the analysis, it was revealed that the lower jaw exoskeleton makes it possible to qualitatively fix the fragments of the lower jaw for the period of fracture healing.

The Creation

In the oral and maxillofacial surgery, there is a requirement to provide the best possible treatment for the patient with mandibular fractures. This treatment presumes application of reduction and fixation techniques for proper stabilization of the fracture site. The reduction of the bone fragments and their fixation is much better performed when geometry and morphology of the bone and osteofixation elements (e.g. plates) are properly defined. In this paper, a new healthcare procedure, which enables application of personalized plate implants for the fixation of the mandibular fractures, is presented. Geometrical models of mandible and plate implants, presented in this research, were created by means of the Method of Anatomical Features (MAF), which has been already applied to the creation of accurate geometrical models of various human bones, plates and fixators. By using such geometrically and anatomically accurate models, orthopedic and maxillofacial surgeons can better perform pre-operative tasks of simulating and planning the operation, as well as an intraoperative task of implanting the personalized plate into the patient body.

Objective: to report a surgical case of comminuted mandible fracture caused by a firearm projectile treated with external fixation. Methodology: male patient, 18 years old, attended the Emergency Department of the Maxillofacial Surgery service after trauma in the mandibular region by a firearm projectile. On clinical examination, edema was observed in the cervical zone II and mandibular region, penetrating orifice of entry of the projectile in the genial region and mobility in the mandibular body. CT scan revealed a comminuted fracture in the mandible. Transcutaneous perforations were performed with pins, anatomical reduction of the fracture and stabilization to the external nail, adapting to the mandibular anatomy. Following postoperative follow-up, the patient progresses without pain complaints, with functional and satisfactory mouth opening, without mobility in bone fragments, and reestablished mandibular framework. Results and Conclusion: mandibular fractures by firearms are frequent in the routine of the buccomaxillofacial surgeon. Cases of bone comminution present individual peculiarities that must be taken into account in their management. The correct indication of external fixation proved to be adequate and satisfactory for cases of mandible comminution.

Objectives: Surgical treatment of patients with multiple mandibular fractures involving condylar segments may be a difficult proposition for a maxillofacial surgeon. These fractures can be double or triple fractures of the lower mandible and can also be associated with other fractures of the face. While many authors have suggested that the conventional approach to reducing and stabilizing a mandibular symphysis / para-symphysis fracture is appropriate before addressing a fractured condyle, there is another school of thought that suggests that the condylar segment should be reduced and repaired first. This article aims to review the results of operations where the reduction and fixation of a fractured condyle is performed prior to other associated mandible fractures, and to explore the effectiveness of various surgical methods including preauricular and retromandibular proposed in this case. Place and Duration: In the Oral and Maxillofacial surgery department of Faryal Dental College, Lahore for two-years duration from Jan 2018 to Jan 2020. Material and methods: The study included 60 surgically treated patients with multiple mandible fractures (double / triple), including the condyle component. For treatment of the fractured condylar segments, the preauricular and retromandibular (anterior parotid-transmasseteric) approach was used. Results: Condyle fracture was the first segment to be managed during sequencing of surgical treatment, regardless of the method used. First, good reduction and stabilization have been achieved with limited complications in treating a condyle fracture. Conclusion: While it is the surgeon's prerogative to sort multiple mandible fractures, addressing the condylar segment first provides the operator with a viable alternative to the conventional technique. Key words: condylar fractures, multiple mandibular fractures, preauricular approach, retromandibular approach

Subject. A literature review is devoted to the urgent problem of maxillofacial surgery and surgical dentistry ― improving the efficiency of rehabilitation of patients with fractures of the lower jaw using kinesiotape. The goal is to study the materials of publications devoted to kinesiotape during traumatic injuries of the maxillofacial region. Methodology. The mechanisms of action of a kinesiological teip applied in the form of applications on the skin are described in detail, which lead to the creation of favorable conditions for sanogenetic processes that are realized in normalizing microcirculation, reducing edema and the severity of pain. An increase in the number of publications on the use of this method in the prevention and treatment of injuries of the musculoskeletal system in athletes was noted. Moreover, at present, kinesioteiping is also used in clinical medicine, for example, in the practice of neurology and orthopedics. According to modern scientific research, the use of kinesiotape in patients with chronic back pain, subacromial impingement syndrome, acute whiplash injury of the cervical spine can significantly reduce the severity of pain. Results. Despite the rather widespread use of the method of kinesiotapeing in sports and clinical medicine, in the available literature there is a small number of works devoted to its use in maxillofacial surgery, in particular for fractures of the lower jaw. The use of the method of kinesiotherapy after surgery for osteosynthesis of fragments of the lower jaw has significantly reduced the level of inflammatory edema and the intensity of the pain syndrome. Conclusions. The presented literature review results indicate that kinesiotherapy is a promising, simple, non-traumatic method of rehabilitation after surgical treatment of lower jaw fractures, which does not have side effects and complications and significantly improves the quality of life of patients. However, scientific studies devoted to the analysis of the use of kinesiotherapy for traumatic injuries of the maxillofacial region are not enough for this period.

ResumoUm dos maiores desafios no tratamento de fraturas cominutivas da mandíbula é restaurar o contorno anatômico das áreas fraturadas, pois, a maioria dos casos apresenta deslocamento ósseo severo e perda óssea que diminuem a previsibilidade da redução dos fragmentos. Nesse contexto o tratamento deste tipo de fraturas mandibulares ainda permanece um desafio para a cirurgia maxilofacial no que se refere à técnica de redução. Nesse sentido, a redução aberta com fixação interna rígida se apresenta como uma boa opção de tratamento, por encurtar o tempo de reabilitação orofuncional e diminuir as chances de infecção. O presente trabalho tem como objetivo apresentar o caso clínico de um paciente do sexo masculino vítima de acidente com animal cursando com múltiplas fraturas de face. A abordagem cirúrgica eleita para o tratamento da fratura mandibular cominutiva foi a redução aberta e instalação de placa de reconstrução e parafusos de titânio. A abordagem aberta evitou o bloqueio maxilo-mandibular pós-operatório em um paciente jovem. Esta técnica permitiu a redução precisa dos fragmentos devolvendo a função mastigatória de maneira precoce.Palavras-chave: Fraturas maxilomandibulares, traumatismos mandibulares, redução aberta, fixação de fratura.AbstractOne of the biggest challenges in treating comminuted jaw fractures is restoring the anatomical contour of the fractured areas. Most cases have severe bone dislocation and bone loss that decreases reduction predictability. In this context, the treatment of this type of mandibular fractures still remains a challenge for maxillofacial surgery regarding the reduction technique. In this sense, open reduction with rigid internal fixation is a good treatment option because it decreases orofunctional rehabilitation time and reduces the chances of infection. The present work aims to present the clinical case of a male patient victim of animal accident with multiple facial fractures. The chosen surgical approach for the treatment of comminuted mandibular fracture was open reduction and installation of reconstruction plate and titanium screws. The open approach favored not performing postoperative maxillomandibular block in a young patient. This technique allowed the precise reduction of fragments and the early masticatory function.Key-words: Jaw fractures, mandibular injuries, open fracture reduction, fracture fixation.

Academician I.P. Pavlov Ryazan state medical University of the Ministry of health of the Russian Federation, 390026, Ryazan, Russian Federation Patients with injuries of the maxillofacial region make up about 30% of all patients treated in the in-patient departments of maxillofacial surgery. Meanwhile, fractures of the lower jaw account for about 70%85% of all fractures of the bones of the face. The need for immobilization is due to the risk of pain and complications (bleeding, microbial contamination, asphyxiation, damage to nerves and blood vessels). The article provides a comparative analysis between temporary immobilization of the jaws using well-known designs and a new universal temporary bus with a channel. We conducted the experiment under simulated conditions using the following splinting structures: a smooth splint bar and a patented temporary splint with a channel for treating jaw fractures (Application No. 2020103350/14 (005106) (22) Application submission date 27.01.2020). From the experimental research complex, it was possible to verify that the methods of temporary splinting of the jaws have their own characteristics of superposition and displacement of structures. It is worth noting that the displacement of jaw fragments occurred in each splinting and this should definitely be taken into account at the stage of first aid. The study also revealed that that the splinting technique for the splint has a number of disadvantages, the most significant of which are the negative impact on periodontal disease, a significant decrease in oral hygiene, and the possibility of secondary infection. Among the obvious advantages of a universal temporary bus with a channel, include the simplicity of applying and fixing fragments, the ability to supply the patient, receive fluids and drugs through the probe, as well as ensuring full breathing in the absence of nasal breathing.

Jaw Fractures

Thing. Among the fractures of the bones of the facial skeleton are most often re-breaking down the lower jaws. The diagnosis of them does not represent difficulties, but despite this, the clinical course of the lower jaw fractures is often complicated by the development of herbal osteomyelitis, which affects the reparative processes in the bone and for the duration of the temporary disability of patients. In connection with the foregoing, the study of factors af-fecting the clinical course of the lower jaw fractures, and the investigator, but on the duration of the temporary disability of patients, is relevant. Purpose — to study the factors influencing the clinical course of mandibular fractures and the timing of temporary disability of patients Methodology. An analysis of 918 stories of the disease of patients with fractures of the Low-er Chelf. The share of traumatic osteomyelitis is determined. Possible factors that contribute to the development of this complication and an increase in the duration of temporary disability is studied. Results. The development of traumatic osteomyelitis in the fractures of the lower jaw is due to the complex of interrelated factors. The most significant among them are: non-timely appeal of the victims of specialized help, senior wagon, poor-quality assistance in the pre-hospital stage, the presence of a stroke of Zu-Ba, having a chronic infection in the periapical tissues and the incorrect tactics of the doctor in relation to this tooth, Multiple fractures on one side of the chemistry, the choice of the method of fixing fragments. The duration of the temporary disability of patients with the development of traumatic osteomyelitis is significantly larger than with the uncomplicated clinical course of the lower jaw fractures. Conclusions. In order to reduce the frequency of development of traumatic osteomyelitis, it is necessary to conduct targeted prophylactic work aimed at improving the quality of the provi-sion of specialized assistance to patients with fractures of the lower person, both in the dogoital and hospital stages.

Aim. To increase the effectiveness of mandibular fracture osteosynthesis by using the composite materials-covered intraosseous screw retainers with active combined cutting edge. Methods. 282 patients with mandibular fractures were examined and operated in the clinic of Oral and Maxillofacial Surgery and Dentistry of Samara State Medical University from 2011 to 2013. Surgeries were performed in 257 (91.1%) patients, including plate osteosynthesis - in 133 (47.2%), intraosseous composite materials-coated screw retainers - in 42 (14.9%), uncoated pins - in 65 (23.0%), bone sutures - in 17 (6.0%). Orthopedic and other methods of bone fragments fixation were used in 25 (8.9%) patients. Proposed composite materials-coated osteosynthesis retainer is a square pin with cutting angle of 60-80° and 4 longitudinal grooves of 5-10 mm. The main part is a two-tier helical ribbon with alternating cutting portions, wherein some areas have the same diameter as the main part of the retainer, and the others are 20-100 microns thinner and are covered with TiC0, 65+25% Ca10(PO4)OH2. RESULTS. A comparative analysis with the traditionally used methods was carried out. The main advantages of the proposed method are rigid fixation of mandibular bone fragments and optimal osteogenesis in complex treatment of patients with trauma. Conclusion. The use of the proposed method of mandibular fractures surgical treatment using intraosseous screw retainers with bioactive coating reduced the risk of complications and the length of hospital stay.

There is currently no consensus on the etiopathogenetic nature of endometriosis. The causes of aggressive, progressive, infiltrative growth of endometrioid tissue also remain unclear. An important problem remains the high recurrence rate of endometriosis, despite the availability of modern drug and surgical methods of treatment. The study of the central signaling pathways and the search for new key molecules is of paramount importance for a better understanding of the pathogenesis of the disease, and is also an important step in the development of new strategies for the diagnosis, prevention and treatment of endometriosis.
