[Total intravenous anaesthesia without medical gases during economic blockade of the country].

In June and July 1992, when the corridor--through which we received the necessary medical supply--was closed, 61 patients (mostly wounded persons, 62%) underwent an urgent surgery. Because of the lack of oxygen and nitric oxydul, the patients were administered the intravenous total anaesthesia without medical gases. The control group was composed of 30 patients operated on in June and July 1991.

Anatomical considerations relevant to implant procedures in the mandible.

The authors review anatomical facts significant for preoperative planning of implant procedures in the mandible. This planning includes the precise evaluation of distinct anatomical factors, such as the position of the mandibular canal, the width of the mandibular cortical plates and the degree of involutive changes of the inferior dental artery. The mandibular canal is usually situated centrally in the mandibular corpus, slightly closer to the lingual cortex in its distal parts; towards the front, it approaches the vestibular cortical layer.

Morphometric analysis of mandibular canal: clinical aspects.

Results of morphometric analysis of the mandibular canal (MC), carried out on 105 conserved mandibles, 70 being dentate and 35 edentate, was performed. The analysis was carried out on consecutive sections, at mutual intervals of 0.5 cm.

[The bone structure of the ramus of the mandible].

Osseous structure of the ramus of mandible (RM) is of a practical clinical significance. Osteosynthesis of fractured segments and the success of the sagittal or the horizontal ramus split osteotomy depends on the cortical bone disposition and thickness. After morphometric investigations of the RM, conducted on 70 mandibles of adults, consecutive horizontal and frontal sections were made.

[The relations of the mandibular canal with the outer surfaces of the body of the mandible and the risks which arise from its injury].

The investigations of relations and position of the mandibular canal (CM) were carried out on 80 mandibles (33 dentulous, 27 partly edentulous and 20 completely edentulous). The studies of relations of CM to the sides of mandibular body were accomplished by morphometric analysis of CM on consecutive transversal sections of mandibular body (54 preparations). The relation of the CM to be buccal or to the lingual side is expressed as the distance from the surface of the correspondent side of the mandibular body, which is shown in Table 1.
