[Post-Covid osteomyelitis of the facial bones]. / Postkovidnyi osteomielit litsevykh kostei.

The pandemic of coronavirus infection existed from 2019 to 2023. The World Health Organization (WHO) has announced on May 5, 2023 that the pandemic had ended. However, it does not cease to have an adverse effect on the health of the world population. Necrotic lesions of the bones of the facial skeleton are now a characteristic sign of a severe coronavirus infection. We conducted a review of scientific publications that reflected the relationship between coronavirus and necrotic processes of the skull bones, methods of treatment, prevention and the latest developments in this direction. The purpose of this article is to review existing studies on Post-Covid osteomyelitis of facial bones, its impact, features of the clinical picture of this disease, analysis of methods and means of treatment of this group of patients. Analysis of literature data has shown that the search for an ideal dressing material continues, especially the developments of native developers stand emphasized. The advantages of modern materials over traditional ones have become unquestionable, but further research in this direction is required.

[The effects of a total TMJ endoprosthesis on the contralateral condyle]. / Vliyanie dvukhkomponentnogo endoproteza visochno-nizhnechelyustnogo sustava na kontralateral'nyi myshchelkovyi otrostok.

OBJECTIVE: To correlate the magnitude of the amount of translation of prosthesis and the native joint, and the postoperative change in the volume of the contralateral condylar process after unilateral total joint replacement. MATERIAL AND METHODS: The study examined 16 patients with post-traumatic jaw deformation treated with unilateral TMJ replacement using total endoprosthesis. The mandible kinematics was recorded using the Cadiax Diagnostic system and correlated with the remodeling of the native joint. RESULT: On average, the group showed an 8.5% decrease in the volume of the native condylar process. In 13 patients, the amplitude of the native joint movement in the mouth opening and the mandible pro- and laterotrusion markedly deviated quantitatively that combined with the translational movement of the TMJ endoprosthesis in all types of mandibular abduction in all the patients. Correlation analysis showed a moderate negative relationship (r= -0.43) in opening the mouth between the amplitude of movement of the native joint and of the endoprosthesis, as well as a noticeable negative strength of relationship. Also, the correlation analysis showed a moderate positive relationship between the change in the native condylar process volume and movement amplitude when opening the mouth, and an inverse correlation of the high strength of relationship between the change in the native condylar process volume and movement amplitude of the TMJ endoprosthesis. CONCLUSION: Electronic axiography found that patients in the postoperative period could restore some of the translational movements even with the attachment of the lateral pterygoid muscle cut off. The main factor influencing the magnitude of the endoprosthesis translational movement is the design of the fossa component: the ratio of the circumferential surface of the fossa to the diameter of the head of the endoprosthesis, as well as the presence of lateral stoppers. The study showed that unilateral TMJ reconstruction provides changes in the volume of the native joint directly related to the amplitude of the movement of the joint itself and inversely correlated with the amplitude of the movement of the endoprosthesis.

All patients underwent a bimaxillary surgery. The three-dimensional CT images were evaluated to assess condylar displacement. RESULTS: The condyle exhibited mainly superior and lateral torque immediately after surgery. Posterior displaced condyles were found in two cases in group 1 (Class II malocclusion). CONCLUSION: The present study found the condyle displacement that can be mistaken as posterior displacement of condyle in analysis of sagittal sections of CT scans.

[Determining the degree of risk of postoperative complications in patients with a benign tumor of the parotid salivary gland]. / Opredelenie stepeni riska vozniknoveniya posleoperatsionnykh oslozhnenii u patsientov s dobrokachestvennoi opukhol'yu okoloushnoi slyunnoi zhelezy.

THE AIM OF THE STUDY: Determination of the risk of postoperative complications in patients after surgical treatment of benign neoplasms of the parotid salivary glands. MATERIAL AND METHODS: The results of treatment of 228 patients with benign neoplasms of the parotid salivary gland in the period from 2019 to 2021 were analyzed. A questionnaire of 7 questions was formed the answers to which allowed patients to be assigned to a certain risk group: low, medium, high or extremely high. This gradation allows choosing the optimal method and scope of surgical treatment for each patient individually. RESULTS: Patients of the first and second groups (low and medium risk) are characterized by the occurrence of temporary isolated facial nerve dysfunction with a short recovery period (up to 1 month), as well as sialocele associated with the preservation of a fragment of the gland. For the patients of the third and fourth groups (high and extremely high risk) in which parotidectomy was performed typical features included persistent paresis of facial muscles and facial soft tissue asymmetry. CONCLUSION: A personalized approach based on determining the degree of risk of postoperative complications helps surgeon in deciding on the scope of surgical treatment from subtotal resection to total parotidectomy.

[The use of magnetic sensory system for mandibular movement patterns recording in patients after TMJ reconstruction]. / Ispol'zovanie magnitno-sensornoi sistemy dlya registratsii patternov dvizheniya nizhnei chelyusti u patsientov, perenesshikh rekonstruktsiyu visochno-nizhnechelyustnogo sustava.

OBJECTIVE: The aim of this study was to record mandibular kinematics in patients after total TMJ endoprosthesis using a magnetic sensory system. MATERIAL AND METHODS: The movement of the mandibular was examined in 10 patients who underwent TMJ reconstruction using total endoprostheses. The condylar range of motion, the angle of the transversal condylar inclination (TCI), the speed of joint movement (max S) and the stability distance between the position at the beginning of movement and at the end (Start/end) of TMJ prostheses and native joints were measured 1 week before surgery (T0) and 12 months after (T1). RESULTS: The study showed an increase in the linear distance of the native joint when opening (p=0.004), protrusion (p=0.004), balancing side (p=0.001) and max S of the native joint and endoprosthesis when opening (p=0.009), working side (p=0.008) and balancing side (p=0.001). A decrease in indicators was observed in the Start/end of the native joint when opening (p=0.035), protrusion (p=0.02), working side (p=0.004), as well as the endoprosthesis relative to the pathological joint when opening (p=0.028), protrusion (p=0.001) and balancing side (p=0.003). CONCLUSION: In the present study, in all cases, a slight but clearly defined translational shift on the side of the intervention was detected on the control condylograms, which can be referred to as «pseudotranslation¼.

[The feasibility of combined lipofilling methods in the treatment of patients with facial hemiatrophy]. / Vozmozhnosti primeneniia kombinirovannykh metodov lipofilinga pri lechenii patsientov s gemiatrofiei miagkikh tkanei litsa.

The basis of Central Research Institute of Dentistry and Maxillofacial Surgery in the period from 2015 to 2018 years there were 30 patients with primary hemiatrophy (group 1) and patients with hemiatrophy after reconstructive operations (group 2) who were examined and treated. The elimination of deformation of soft tissues was performed by combination of micro-, nano- and classical lipofilling in two sessions with an interval of 6 months. To determine the deficit of tissue volume on the affected side before and at the treatment stages, a computer tomography was performed with the construction of the mathematical surface of the face. A study of the nature of the changes in the underlying structures in each group was carried out using ultrasound scanning and LDF studies. The use of non-invasive research methods allows us to track the dynamics of skin transformation. Based on the results of the treatment in 2 groups, a combination of micro-, nano- and classical lipofilling did not only increase the volume and eliminate deformation soft tissue, but also transform the quality of the skin. Thus, the combination of various lipofilling methods allowed to achieve a more stable result and increase the efficiency of treatment.

[Bone anchored auricular prosthesis for patients with grade III microtia]. / Éktoprotezirovanie ushnoi rakoviny s oporoi na vnutrikostnye implantaty u patsientov s mikrotiei III stepeni.

The aim of the study was to assess the effectivity of auricular prosthesis on intraosseous implants in patient with grade III microtia. The study included 7 patients (5 males and 2 females) aged 18 to 45 years with hemifacial microsomia and grade III microtia operated in Central Research Institute of Dentistry and Maxillofacial Surgery in 2013-2016. Number and position of intraosseous implants was determined by reverse planning based on CT representing hard and soft facial structures. Patients were followed-up for 6-36 months. Good esthetic results were obtained by minimally invasive surgical procedure and short post-op rehabilitation. However these results required meticulous virtual planning and manufacturing of surgical template. The described method promotes very fast medical and social rehabilitation of patients with severe microtia.
