[ASSESSMENT OF COMBINED PROPHYLAXIS OF PATHOLOGICAL POSTOPERATIVE FACE SKIN SCARS ACCORDING TO THE VANCOUVER SCALE].

The aim of the research was to study the effectiveness of combined prophylaxis of pathological postoperative face skin scars according to the Vancouver scale. The research involved 29 patients, aging 16-48 years old, who underwent maxillofacial surgery by extraoral accesses with wound primary intention healing. The patients were divided into three groups: the control group, which involved the patients, who after the surgery did not undergo any preventive measures to avoid pathological skin scars development, and two study groups. The patients of the first study group underwent the monotherapy comprising three sessions of extracorporeal shock wave therapy once every 4-5 days. The patients of the second study group underwent three sessions of extracorporeal shock wave therapy once every 4-5 days and local use of silicone gel Strataderm. The Vancouver scale was used to evaluate clinically the effectiveness of the suggested methods of pathological scars development prevention. It involved evaluation (in points) of their consistency, pigmentation, and vascularization. The scars were assessed on the 7th, 30th day after the surgery and in 6 months. Positive results were attained in the patients of both study groups; they were manifested by increased elasticity and compliance of scars, pigmentation becoming of just about surrounding skin natural color, normalization of blood supply to scars, and more rapid disappearance of suture marks. However, these positive signs were more significant in the patients of the second study group that allowed us concluding that combined use of extracorporeal shock wave therapy and local applying of silicone gel Strataderm was advisable.

[JUSTIFICATION OF CHOICE OF THE POSITION OF THE REINFORCEMENT ELEMENT OF A GLASS-FIBER ADHESIVE TIRE BASED ON THE STUDY OF DIAGNOSTIC MODELS IN THE ARTICULATOR AND THE FOLLOWING PARALLELMETRIC RESEARCH].

The aim of the study was to develop the most optimal variant for placing the reinforcing element of a fiberglass splint with the mobility of the anterior teeth on the basis of a parallelometric study of the diagnostic models of the jaws depending on the type of occlusion and the degree of bone resorption. For the most optimal variant of the placement of the reinforcing element of the adhesive splint with orthognathic bite and deep incisal overlap, the front slope of the model was selected with the transfer of the reinforcing element of the adhesive splint onto the lingual surface. With direct, prognathic and progenic bite and bone resorption up to » height (according to retrography data), the back slope of the model was selected with the placement of the reinforcing element of the adhesive splint on the vestibular surface of the lower jaw. The disadvantage of locating the reinforcing element on the lingual surface when the incisors were crowded was that after the application of the splint and inter-proximal adaptation, the change in the position of the teeth was not corrected. On the contrary, when applying an adhesive splint on the vestibular surface with the help of restoration, it was possible to completely restore the original position of the teeth and fix it for a long time.
