Thermographic exploration of the parotid region.

Thermography was applied in the pathology of the parotid area in order to see if it is able to complement the clinical examination. The authors present their experience on 17 cases. They could be classed in 3 groups: lesions with normal thermography or non significant modifications, lesions with hypothermia, lesions with hyperthermia. The results indicate that in some cases the information obtained is very useful although up to now differentiation of hyperthermia of different origins is difficult.

[Effect of insulin on the development of the tooth germ in mice].

After recalling the interactions affecting dental differentiation, the authors analyze the effects of various concentrations in insulin on dental rudiments cultivated in vitro. They found: an oedema causing histological lesions, no anticipation of cell differentiation or stimulation of collagen secretion, a decrease in mitotic activity but stimulation of thymidine 3H incorporation after short contact times.

[Mandibular synthesis. Placement of the synthesis as a function of mandibular stress].

After recalling Michelet's principles of mandibular osteosynthesis, the authors relate their experiences after 18 months of biomechanical analysis. They define the best locations for osteosyntheses according to calculations of when flexion and torsion occur, taking anatomical conditions into account. Details are given of the position of the plate or plates according to the location of the fracture or osteotomy (horizontal branch, symphysal and para-symphysal region and angle). Analysis of stresses within the osteosynthesized mandible has resulted in the development of what seems to be a reliable medium. One hundred anf forty facial osteosyntheses they have carried out confirm their faith in the safety of the method.

[Fronto-malar osteosynthesis by means of screwed plates].

The external orbital apophysis provides a zone of solid anchorage for the treatment of fractures as well as for the immobilization of osseous fragments after facial osteotomy. While proposing new miniaturized material the authors present 45 cases of fronto-malar osteosynthesis carried out in one year. They recall that solid immobilization by plating avoids inter-maxillary blockage, and is the only means of restraint among those presently used which is capable of opposing late post-operative recession. Consequently after facial osteotomy, the plates are left in place for 12 months. They are removed under local anethesia.
