[Osteoplastic operations in the anterior part of the mandible for correction of malocclusion]. / Kostno-plasticheskie operatsii v perednem otdele nizhnei chelyusti pri korrektsii anomalii prikusa.

Correction of disorders during transformation into one of the most difficult tasks, both in orthodontics and in maxillofacial (orthognathic) surgery. This article presents two clinical cases of median osteotomy/ostectomy. The stages of operations are described. Surgical technique of transversal correction by osteotomy/ ostectomy is presented. Operation is combined with bilateral retromolar osteotomy. Three dimensional fragments moving helps to change lower jaw shape. Indications for this surgical manipulation: one or two side cross-bite, discrepancies between size of teeth and length of alveolar bone (lower macrognathia, microdentia, extra-teeth, huge diastema), asymmetry of mandible.

[Combined therapy with elastic bands and splints in patients with masticatory muscles hypertension]. / Sochetannoe lechenie patsientov s gipertonusom zhevatel'nykh myshts s pomoshch'yu elastichnykh lent i kapp.

THE AIM OF THE STUDY: Was to investigate the effectiveness of combined treatment with elastic bands and splints in patients with masticatory muscle hypertension. 103 patients (37 men and 66 women) aged from 21 to 65 years were examined. The diagnosis was made based on clinical and instrumental (electromyography) methods. Pain intensity was determined using a visual-analog scale (VAS). Elimination of masticatory muscle hypertension in patients of the first group (51 people) was carried out using only splints while patients of the second group (52 people) had a combined therapy with elastic bands and splints. In the second group of patients reliable reducing of pain intensity was observed by day 14 from the start of therapy (4.54±0.5 points), while in the first group of patients it was discovered only by day 21 (5.08±0.6 points). Reliable changing of the bioelectrical activity of masticatory muscles in the second group of patients was observed by the beginning of second week from the start of preliminary therapy, while in the first group of patients it was discovered only by the third week. Thus, the proposed method of masticatory muscles hypertension treatment using elastic bands and splints has features, favorably distinguish it from the other methods of the therapy, because it provides sparing functioning condition for masticatory muscles.

[Protocol of cone beam computed tomography analysis for patients with craniomandibular dysfunction]. / Protokol analiza konusno-luchevoi komp'yuternoi tomografii u bol'nykh s kraniomandibulyarnoi disfunktsiei.

The article presents a detailed protocol of cone beam computed tomography (CBCT), which includes not only the classic analysis of dentoalveolar and skeletal disorders, but diagnosis of cranial patterns (craniocervical cephalometric analysis by M. Rocabado, cephalometric diagnosis by Sassouni PLUS), analysis of transverse jaw sizes (Penn analysis) and measuring the volume of the airway for screening of obstructive sleep apnea. The literature review was conducted using the PubMed in the Scopus and Medline electronic databases through April 2020. Combining several methods of interpretation of CBCT in a single protocol will allow doctors to obtain a more complete amount of information to make a complete plan of comprehensive treatment.

[Factors determining prognosis of patients with stable ischemic heart disease (results of a five years prospective study)].

Risk stratification seems to be very important in patients with stable coronary artery disease (CAD). However, the prognostic scales are now available only for the early risk assessment in patients with acute coronary syndromes and in patients undergoing percutaneous coronary interventions. Aim of the study was to assess the frequency of cardiovascular events (CVE) during 5 years of follow-up in patients with stable CAD and to construct a long-term risk prediction model for these patients. 503 patients (mean age 59.4 years) were included in the study. The follow-up period ranged between 3.0 and 7.5 years (mean 5.0 years). Main end points were fatal and non-fatal cardiovascular events: cardiovascular death, acute coronary syndromes, ischemic stroke, transient ischemic attack, peripheral arterial thrombosis, and need for revascularization in any affected vascular area. Total frequency of events was 31.0% (5.7/100 patient years). Independent predictors of events were: severity of angina, three vessel coronary disease, previous myocardial infarction, previous stroke/ transient ischemic attack, peripheral arterial disease, obesity, chronic kidney disease and history of erosive gastritis. The presence of more or equal 3 risk factors was significantly associated with increased frequency of CVE.
