[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+/-6.8 min. Combined intravenous anesthesia with propophol, phentanil, atracrium besylate was used for all patients. The utilization of a laryngeal mask (LM) for respiratory support was used in the first group (20 patients). An tracheal intubation (TI) was made in the second group (20 patients). In total myoplegia, the installation of LM was simple. Undesirable laryngo-pharyngeal reflexes were not noticed. The reaction of cardiovascular system while installing. LM was absent unlike TI. As for the gas exchange no difference was noticed in both groups (p>0.05). After the operation the patients of the first group recovered quicker than the patients of the second group (p<0.05). It is the result of reducing the amount of relaxants in the first group (p<0.05). Hence, anesthesia with LM may be regarded as alternative method of anesthesiological provision for a maxillofacial operations of short duration.

[Endoscopic technologies in maxillofacial surgery].

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. The results of utilization of endoscopic technologies in maxillofacial surgery are analyzed and their high efficacy and good prospects are demonstrated.

[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. A clinical example of using a porous permeable implant is offered. The implant designed as a mandible was used for repair of an extensive mandibular defect. Good immediate and remote results of operations indicate good prospects of using such implants.

[Current problems in the diagnosis and treatment of injuries to the temporomandibular joint].

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. Our investigation has shown that condylar fractures in the region of condylar base and neck are combined with the injuries of the articular disk and capsular-ligamentous apparatus in 54.1 +/- 5.4% cases, mandibular head fractures with its dislocation--in 100%. The term "TMJ injuries" reflecting the injuries of bone and soft tissue structures of the TMJ has been introduced. The classification of TMJ injuries including TMJ contusion, mandibular dislocations, condylar and glenoid fossa fractures, the injuries of the articular disk and capsular-ligamentous apparatus has been developed. Distant results of traditional methods of treatment used in TMJ trauma have been studied and the necessity of the restoring of correct relation: glenoid fossa --articular disk--mandibular head--has been shown. The method of TMJ reconstruction consisting in the restoration of TMJ bone structures and the articular disk and capsular-ligamentous apparatus has been developed.

[The classification of diseases of the temporomandibular joint].

There were 2040 patients with temporomandibular joint (TMJ) diseases in the investigation including clinical, physiological, X-ray methods of research, contrast arthrotomography, computer arthrotomography and magnetic resonance tomography. The changes of structure in different lesions were estimated. The result of received data was elaboration of classification of TMJ internal derangements with estimation of clinical forms in according with structural changes and characteristics of syndromes.

[Self-contained cryoapplicators made of porous titanium nickelide in the treatment of precancer of the lip and oral mucosa].

A set of autonomic cryoapplicators of porous titanium nickelide is designed, their physical parameters described, and cryogenic properties studied on gelatin model. Ninety-eight patients with precancer diseases of the red lips and buccal mucosa were treated using these applicators. The applicators are easy to use and meet the requirements to cryoinstruments. Cryoexposure is to be performed during the first minute after coolant charging, when the temperature of the applicators is close to the nitrogen one. The larger is the diameter of the working piece of the applicator and the larger is the device, the more ice is formed. The depth of freezing is 2 to 6 mm. The choice of an applicator, duration of cryoexposure, number of cryocontacts, and cycles of freezing and thawing depend on the form of precancer disease, size of lesions, and degree of the pathological changes. Good results were attained in 96.9 +/- 1.6% of patients.

[Reconstruction of the visceral cranium by the replantation of a resected bone segment subjected to extracorporeal freezing in benign tumors and dysplastic processes].

The new method for surgical treatment of benign tumors and dysplastic processes in the facial skull bones includes resection of the involved segment of the bone, its mechanical treatment, extracorporeal freezing, sterilization, and replantation. Biophysical studies revealed that 10-min freezing of the preparation in liquid nitrogen followed by slow defrosting kills tumor cells. Animal experiments demonstrated excellent osteoplastic properties of thus treated replants. Based on the results of treatment of 29 patients, the authors defined the indications for such treatment and demonstrated its high efficacy in benign tumors and dysplastic processes in the facial skull.

[Transtracheal jet pulmonary ventilation as a measure for preventing hypoxia during reconstructive maxillofacial operations].

Anesthesia including high- or low-frequency transtracheal jet ventilation of the lungs was used in 52 patients with maxillofacial abnormalities subjected to repair surgery. The number of respiratory cycles was 20 per min in 1 group and 120 per min in the other. Intubation of the trachea was started 20 min after ventilation was started. Transtracheal jet ventilation of the lungs prevented hypoxia during intubation of the trachea in such patients. High-frequency jet ventilation of the lungs may be a method of choice in such cases.
