In 42 patients with pathology of face cranium tracheal intubation was performed by different methods--intubation with artificial jet high frequency lung ventilation (I+AJHFV) and fiber optic intubation (FOI). It was established that more favourable conditions for intubation were created when I+AJHFV was used. FOI with preserved consciousness and spontaneous breathing in patients with pathology of maxillofacial region reduces the time factor significance but demands significant sedative preparation of the patient.

In experiment on 30 corpses of adult people criteria of an operational wound (depth of a wound, a corner of operational action, an axis of operational action, a corner of an inclination of operational action) were studied at preauricularis, intrauricularis, intrauriculo-temporalis and posterior mandibullaris access to temporo-mandibular joint (TMJ). New surgical intrauriculo-temporalis access to the joint is substantrated. On the basis of the analysis of 289 operations at 268 patients the indications to a choice of surgical access were developed at various diseases and damages of TMJ.

[Efficacy of laryngeal mask use during anesthesia in cases of short-term operations in maxillofacial area].

40 patients, with the pathology of maxillofacial area were investigated during the operation. The operation lasted 60.5+/-6.

[Technique of X-ray computed arthro-tomography in the diagnosis of internal disorders of the temporomandibular joint].

141 patients suffering by internal derangements temporomandibular joint are surveyed with the help x-ray computed arthrotomography. The opportunity of reception of precise intra-articular elements after introduction of contrast substance allows treat results of researches with high reliability. X-ray's data received with the help CT are investigated and systematized.

[Magnetic resonance tomography of temporomandibular joint].

The paper shows the place of magnetic resonance imaging among other radiation diagnostic techniques in detecting abnormal changes in the temporomandibular joint. The authors' own data were based on the results of 315 examinations. The paper describes the technical features of examination of the joint and shows it possible to visualize different anatomic structures on T1-, T2- and Pd-weighted images.

[The treatment of patients with traumatic osteomyelitis of the mandible by using porous permeable titanium nickelide implants].

Use of titanium nickelide based porous permeable implants for repair of postosteomyelitis mandibular defects is discussed. Five patients with mandibular defects of different location and extent were operated on. Surgical methods are described.

Endoscopic operations in 107 patients with numerous maxillofacial diseases are analyzed. Endoscopic technologies were used in diseases of the maxillary sinus, temporomandibular joint, injuries to the facial nerve, and cysts of the jaws. New methods for surgical treatment of mandibular fractures, zygomatico-orbital complex, cysts of the jaws are proposed.

Complex examination of 2103 patients with temporomandibular joint (TMJ) injuries was carried out. This examination included contrast arthrotomography, computed tomography (CT) and MR tomography of the TMJ. It gas been established, that in mandibular condyle fractures not only bone structures of the TMJ, but also soft tissue ones (the articular disk and capsular-ligamentous apparatus) are being injured.

Animal experiments demonstrated excellent osteoplastic properties of thus treated replants.

Clinical, x-ray, and morphologic studies have demonstrated that formalin-treated allotransplants are the optimal plastic material, providing restoration of bone intactness, preservation of dental roots, and the osteoid type of dental root join with the bone regenerate. Dental roots within surface-demineralized and lyophilized allotransplants are resolved in the course of their replacement with newly developing bone tissue.
