Abstract

The aim of the study. To study of the state of regional blood supply in the tissues of the vestibule of the mouth maxillomandibular anomalies on the background disorders of the architectonics of the vestibule of the mouth. Research methods. 60 patients with maxillomandibular anomalies and disorders of the architectonics of the vestibule of the mouth were examined and treated. The age group of patients is 15–17 years old. The first group consisted of 30 patients who had plastic surgery of connective strands by the classical method, where the wound was healed by secondary tension. In group 1A (15 people) in the postoperative period, chlorhexidine-denta was prescribed, in group 1B (15 people) – chlorhexidine-denta and gengigel. In the second group (30 patients), plastic surgery of connective strands were performed using our proposed method, where the wound heals by primary tension. In group 2A (15 people) in the postoperative period, chlorhexidine-denta was prescribed, in group 2B (15 people) – chlorhexidine-denta and gengigel. In comparison group where were 15 persons without maxillofacial anomalies, deformities, oral habits and periodontal status. All patients underwent rheography of the vestibule of the mouth with the help of the following devices and programs: Rheograph “DX”, “DX-Complex Regina 2002”. Rheoelectroencephalograph was a recording device. The study was conducted before treatment and after surgical correction (1 month, 6 months, 12 months). Scientific novelty. The results of investigation of regional circulation of the tissues of the vestibule of the mouth showed the presence of blood circulation deficit and reduce the trophic tissue, which was indicated by the increase in vascular tone index (VTI), venous outflow index (VOI), peripheral resistance index (PRI) and reduce of extensive blood flow index (EBFI) аnd rheographic index (RI) (p<0.05). Qualitative characteristics of rheograms were correlated with quantitative characteristics. After the treatment, positive dynamics of rheographic indicators were observed in all groups, however Conclusions. The results of the rheographic study in terms of quantitative and qualitative characteristics showed that patients with maxillomandibular anomalies and disorders of the architectonics of the vestibule of the mouth (15–17 years old) have pronounced stagnation in the periodontal tissues, insufficiency of blood circulation, and impaired venous outflow. Surgical correction by our proposed method using palatal mucosal grafts and gengigel in the postoperative period ensures normalization and stabilization of rheographic indicators in the early and longterm follow-up. Key words: vestibule of the mouth, buccal frenulum, periodontium, oral mucosa, allogeneic transplantation, blood supply.
