[Development and evaluation of simulation methods for manual skills training in 'Removable dentures' module]. / Razrabotka i otsenka éffektivnosti simuliatsionnoi metodiki obucheniia manual'nym navykam po moduliu 'Nes''emnoe protezirovanie.

To determine the effectiveness of a simulation method of teaching manual skills modulo 'removable dentures' in a clinical setting. MATERIAL AND METHODS: The material 1 phase of the study were 82 people, students of 3 courses, divided into a control group where the training was conducted with the use of standard phantoms and group study which used a dental simulator CDS 100 of V generation. Material 2 stages presented 48 people who participated in phase 1 and divided into groups similar to the 1 stage, young professionals in 2016. An objective assessment of the quality of preparation for 2 stages made with a scanner Zirkozahn arti s600. RESULTS: In the control group, the main reason for the need for additional correction of the abutment teeth as 1 and 2 is the inadequacy of stage periodontal ledge factor ANOVA with the indicator 1.1 for one phase of the study and 1.15 for 2 stages, indicating that the statistical predictors in this group identity. The group studies found no statistically significant difference in the quality of the executed periodontal ledges 1 and 2 stages of the study, 0.9-way ANOVA factor, which indicates the statistical significance of the predictor as pre-acquisition movements automatism acquired while working with the simulator. CONCLUSION: The use of an interactive computer simulation CDS 100 provides a higher level of acquisition, and the main 'survival' of practical skills, confirmed by subsequent clinical practice, compared with the classical form of education.

[Surgical treatment of patients with arteriovenous head and neck angiodisplasia]. / Khirurgicheskoe lechenie bol'nykh s arteriovenoznymi angiodisplaziiami v oblasti golovy i shei.

The aim of the study was to assess the results of surgical treatment in 74 patients with extensive arteriovenous angiodisplasia in the head and neck area. All patients underwent complex examination including ultrasound, CT and MRI with contrast and selective carotid angiography. The lesions excision was performed after endovascular embolization and soft tissue defects were restored by various methods selected according to prevalent vascular lesion type (arterial, arteriovenous, venous, capillary) and blood flow values (high flow, low flow, mixed). Good and satisfactory esthetic results were seen in 95.2% of cases, lesion relapse was detected in 4.8% of cases by 12-18 months follow-up. Endovascular embolization proved to decrease the intraoperative bleeding risk, prevent lesion relapse and minimize the size of the lesion improving the results of radical treatment. Local flap reconstruction usually results in good esthetic results. By local soft tissue deficiency distant free flaps or microsurgical complex flaps may be used.
