[External fixation devices in maxillofacial surgery].

External fixation devices have relatively little application in stomatology, but they are indispensable in certain situations. Equipment presently available for use by maxillofacial surgeons is relatively reduced in number, and two new fixation devices are proposed : a Jacquet type miniaturized fixation device and one of the Sorem type particularly adapted for the mandible.

[Mandibular reconstruction using an iliac crest free flap vascularized by the deep circumflex iliac vessels. A clinical study apropos of 30 cases].

Thirty cases of mandibular defects were reconstructed with a free iliac flap vascularised by the deep circumflex iliac vessels. Twenty five of these cases involved soft tissue damage with a defect of the mandible. The surgical procedure described by I. Taylor was used. Three anatomical variations of the pedicle were found. The features of the iliac bone are particularly suitable for mandibular reconstruction. The natural shape of the iliac bone does not require complex osteotomies and its healing capacity allows simple osteosynthesis. The thickness of the muscular pedicle, and thus the flap, is determined by the position of the lower edge of the skin components with respect to the iliac crest. This type of flap currently remains very useful in reconstruction of major mandibular and adjacent soft tissue destruction because of the very low incidence of failure (2 cases) and complications.

Reconstruction of defects of the mandible.

A series of 14 mandibular reconstruction in 13 patients with chips of autogenous, cancellous bone and marrow supported by a titanium mesh tray is presented. The mandibular defects were the results either of operation for carcinoma of the tongue and the floor of the mouth or trauma. Satisfactory rehabilitation was accomplished in 11 patients. The advantages of this technique are ease of accomplishment, ability to replace long and awkardly shaped segments, less shrinkage due to bone resorption, and shorter intermaxillary fixation.

[Correction of mandibular defects with preserved homologous bone sterilized in ethylene oxide].

The authors have elaborated the technic for procurement of homografts from the lower jaw bone taken from cadaver-donors, without observing aseptic rules, with their subsequent ethylene epoxide sterilization in a portable chamber. Experimental studies have demonstrated that ethylene epoxide renders no negative effect on osteoplastic properties of the homograft, the rate of its reconstruction was dependent on the method of preservation. The results of osteohomoplasty for mandibular defects in 46 patients are summarized.

[Prosthetic treatment of mandibular pseudarthrosis using an articulated prosthesis].

Two cases with complete loss of the tooth-bearing portion of the mandible were repaired with a prosthesis. This type of defect can involve the loss of a large number of teeth and aggression to the remaining teeth must be limited as much as possible. A two-part "articulated" prosthesis with two rings appears to be the best adapted system. This method takes into account the requirements of for additional conventional prostheses and thus makes it possible to save the remaining teeth.
