ABSTRACT
Prevention of postoperative deformation of the nose after bone repair surgery (transposition of the maxillary complex forward) is an important problem. The proposed method for osteotomy of the maxillary complex prevents or minimizes the postoperative deformation of the nasal cartilage after transposition of the maxillary complex. The method was used with good results in 35 patients with upper microretrognathia.

The results of treatment of patients with congenital combined deformations of the jaws are assessed after 6 months to 8 years. The results are analyzed for 96 patients with maxillary micro- or retrognathia and mandibular macro- or prognathia, maxillary macro- or prognathia, and mandibular micro- or retrognathia. Remote results were assessed by clinical, x-ray, and functional methods of examination. Stable esthetic and functional results were attained in all patients, which were observed during both immediate and remote periods of follow-up. No signs of deformation relapses were observed in any case.

Immunologic studies were carried out in 55 patients with local malignant processes in the maxillofacial area and neck before and after surgery. The patients were divided into 2 groups: group 1 (N = 20) received no specific therapy before surgery, group 2 (n = 35) were administered radiotherapy in a total focal dose of 56-65 Gy before the operation. The findings evidence that radiotherapy augments B and T system immunodeficiency manifestations after surgical stress. Postoperative complications in the patients administered radiotherapy before surgery are due to not only immunodeficiency, but to the initial presence of an infective agent as well. Immunocorrective therapy before and after surgery may be recommended to patients whose immunity parameters are shifted.

Polarography and thermometry were employed in examination of the buccal mucosa in 62 patients after combined treatment and primary plasty for malignant tumors of the maxillofacial area. Measurements of pO2 and buccal mucosa temperature were found to yield objective data on the function of the accepting bed in restoration surgery for postoperative defects and to be helpful for the prediction of local complications. Preoperative irradiation according to intensive concentrated scheme induces less marked changes in the mucosa, this being of prophylactic value in cases when local complications develop. The possibility of local complications increases when pO2 reduces twofold and lower vs. the initial level before irradiation.

An analysis of causes of bleedings in 19 patients with malignant tumors of the head and neck has been made. The combined treatment was performed for the III-IV degree tumorous process. As a rule, the bleeding was of erosive character due to ingrowth of the tumor into the walls of major vessels. Alterations of the vascular wall after radiation therapy make the arrest of bleeding in the wound impossible. So, the most reliable method is ligation of the vessels at length.

The microcirculation changes were detected in tissues within and beyond the irradiated area. The changes were marked to a different degree depending on the ionizing irradiation dose and the time since its termination. The microcirculatory changes were less pronounced in the major cerebral vessels' body. The data suggest that microcirculation could provide an objective test in planning the local plastic surgery in the zones of irradiated skin malignant tumors in maxillofacial and haired regions of the head.
