[Effects of blood substitutes of different pharmacological groups and the mode of their injection on the bloodflow of rats].

Central and peripheral bloodflow before and after intramuscular and intravenous injections of 0.9% NaCl (control groups, n=20) and perfluothane (n=20) in a dose of 5 ml/kg was studied in 40 Wistar rats. Dopplerographic study of the bloodflow was carried out on a diagnostic device Biomedical AU-5 (Italy). The study showed that intramuscular injections of both 0.9% NaCl and perfluothane did not lead to a significant increase of the bloodflow, but perfluothane caused a significantly greater increase of both arterial and venous bloodflow in the injection zone in comparison with the control. Intravenous injection of perfluothane increased significantly the systemic and local bloodflow in comparison with the baseline level and control, while total peripheral resistance was decreased.

[Comparative evaluation of classical sinusotomy and endoscopic interventions on the maxillary sinus in odontogenic sinusitis with evaluation of the transporting function of ciliated epithelium and sinus aeration].

In 2002 a total of 98 patients were operated on for odontogenic sinusitis, 49 of these were operated on by endoscopic methods and the rest by classical methods. The transporting function of the epithelium in the nasal cavity and maxillary sinus and the maxillary sinus aeration were evaluated. Pneumatization of the sinus was completely restored and the transporting function of the ciliated epithelium was less disturbed in the patients operated on by the endoscopic method, that is, the mechanisms of maxillary sinus cleansing from secretions were retained, which led to stable cure.

[Comparative clinical and x-ray evaluation of osteosynthesis methods in patients with posttraumatic defects and deformations of the upper and middle zones of the face].

The results of treatment are compared in three groups of patients treated by various methods of osteosynthesis. In group 1 (n = 203) osteosynthesis was carried out using wire suture. In group 2 (n = 231) titanic miniplates and screws were used. In group 3 (n = 21) combined methods were used (simultaneous fixation by wire sutures and titanium miniplates). Indications to the use of different osteosynthesis methods are defined, errors and complications in osteosynthesis in the upper and middle zones of the face are analyzed.

[Gun-shot wounds of the face under conditions of local and boundary conflicts].

Analysis of the incidence, types, and severity of maxillofacial wounds inflicted during local and boundary conflicts showed increased incidence of the most severe wounds with injuries to both jaws. The efficiency of medical care rendered to victims with facial wounds is determined by the level of specialized training of nurses and physician's assistants.

[Results of the facial skull bone defects and deformations repair by modern methods for plasty and fixation of bone fragments].

Methods of reconstructive maxillofacial operations bringing about the best functional and esthetic results are analyzed. Surgical methods for repair of maxillofacial bone defects and deformations with the use of transplants and different methods of their fixation depending on the tissues at the site of defect (deformation) in patients with acquired and congenital abnormalities of the facial skull have been developed and are used at Central Institute of Dentistry. Osteosynthesis using titanium constructions and compression-distraction devices is acknowledged as an effective method of bone repair operations on the face. It notably reduces the duration of operation and prevents the relapse of the deformation. Analysis was carried out on extensive clinical data (more than 1000 patients), which allowed an objective evaluation of remote results of plastic repair of bones and helped define the indications and contraindications for such operations.

[Study of protective effect of perftoran on a skin flaps].

Differences in the levels of tissue respiration in the rat skin flaps incubated in perfluothane (PF) and normal saline (NS) are regarded as an evidence of local PF effect on tissue substrate. The complex of metabolic changes in the skin fragments under the effect of PF in comparison with skin fragments incubated in NS indicate a protective effect of PF on tissue substrata. Decreased content of malonic dialdehyde and a slower accumulation of tissue liquid in skin flaps incubated in PF, in comparison with the fragments incubated in NS, is worthy of note. It indicates that incubation in PF (in comparison with incubation in NS) is less harmful for cell membranes and induces lesser disorders in water-salt metabolism and edema which are usually associated with tissue lesions developing under conditions of trophic deficiency.

[The delivery of qualified care to patients with maxillary and craniofacial pathology].

Problems of timely qualified care of patients with craniofacial injuries are discussed. The number of patients with deformations developing as a result of unqualified care is increasing. The authors validate the need in specialized centers of craniofacial surgery. Special attention is paid to the problem of training highly qualified specialists in this sphere.

[The current potentials of maxillofacial surgery].

Autotransplants of membranous origin and titanium constructions were used in 462 patients with posttraumatic defects and deformations of the upper and medium zones of the facial skeleton. Stable functional and cosmetic results were attained in repair of diplopia and enophthalmos. Surgical methods proposed by the authors accelerate patients' rehabilitation.

[Congenital craniofacial pathology].

The possibility of using compact nonresorbed hydroxyapatite ceramics as synthetic bone plastic materials is discussed. Results of follow-up of 11 patients with congenital and posttraumatic deformations of the craniofacial skeleton are analyzed, to whom hydroxyapatite-based ceramic blocks were implanted for both contour plasty and for repair of bone defects. Methods of the operations with hydroxyapatite-based implants and titanium devices for fixing bone fragments and ceramic blocks are described.

[Anesthesia in cranio-facial surgery].

Reconstructive operations on the facial skeleton and on the skull have been widely introduced in surgery. Increment of indications and augmentation of traumaticity from surgical interventions pose to anesthesiologist a set of such problems, as tracheal intubation, antinociceptive protection, prevention of hepatocerebral encephalopathy. The peculiarities of cerebral and hepatic circulation and metabolism as well as approaches in anesthesia and craniofacial surgery are discussed.

[Developmental defects of the facial the skull in some forms of craniosynostosis].

Changes in the facial skull of 74 patients with untimely synostosis of craniocerebral sutures and pathologic shape of the cerebral skull are characterized. All the patients presented with shortened base of the skull, gross deformations of the facial skull. Certain regularities in the formation of these defects were distinguished.
