[Condylar retrusion in the algo-dysfunctional syndrome of the mastication apparatus].

Although T.M.J. dysfunction-pain syndrome is a multicausal affection, it is obvious that occlusal disturbance is one of the greater etiologic factors. In order to evaluate the role of condylar position in the glenoid fossa, a statistical study has been made on a 16 patients series. These patients presented an uni- or bilateral T.M.J. dysfunction-pain syndrome without arthrosis, ankylosis or traumatologic deformation. The vertical and horizontal relationships of the mandibular condyle to the temporal were quantitatively evaluated from lateral tomographs. Pain and clicking were noted (Y or N) for each of the 32 T.M.J. Condylar position doesn't seem to have any relation with clicking, which is present in cases of meniscus anterior displacement. On the contrary, condylar horizontal retrusion is statistically connected with pain (p less than 0.05) even if one can see condylar retroposition without pain. On the other hand, vertical changes in condylar position cannot be connected with pain. The importance of condylar retrusion in the pain-group can surely be related to inflammatory histologic injuries at the level of the posterior disc attachment. Then, in these cases, the etiologic treatment must be focused on anterior mandibular release by orthodontics, prosthetics or orthognathic surgery.

[The value of miniature compression screws in maxillofacial surgery].

According to the well-known principle of compression, a new kind of screw has been developed. It is a development of the miniaturized Michelet-Champy osteosynthesis device which we have used for the last 10 years in maxillofacial surgery. These traction-screws were initially elaborated for rigid stabilization after sagittal ramus osteotomies such as Obwegeser-Dal Pont. Usually, three screws are inserted at each side, via a transjugal approach. It is then possible to remove the intermaxillary fixation device at the end of the surgical procedure. However, these screws are also useful in other cases: for other kinds of mandibular osteotomies (visor osteotomy for instance), in traumatology (oblique mandibular or condylar fractures) or for fixation of onlay bone grafts on the facial structures. When iliac bone grafts, which are essentially cancellous bone are used, it is possible to use a small metallic ring to avoid penetration of the head of the screw into the graft. The screws can be inserted by a cutaneous punctiform incision when it is impossible to pass the screwdriver through the buccal incision. In all cases, this material is particularly easy to insert, allows good fixation, permits a solid interosseous compression, and is particularly well tolerated. The main drawback is the difficulty of choosing the right length of the screws because only two lengths are available at the present time. Despite this problem, these mini traction-screws seem to be useful for maxillofacial surgeons.

[Modifications in the vertical position of the stomion in facial osteotomies and osseous genioplasties].

A retrospective statistical analysis is made on 45 patients who have undergone a facial osteotomy. The authors study the vertical changes of the stomion on pre- and post-operative lateral cephalograms. Considering the bad initial results, it has been necessary to create subdivisions on the surgical procedure and to work on homogeneous groups. The results of this study led to the following conclusions: the stomion follows the vertical displacement of the maxilla on an approximative ratio of 1/3, with rather great variations between the subjects; the functional osseous genioplasties, specially with vertical displacement, are not accompanied by significant vertical changes in the position of the stomion. Furthermore, it is obvious that it is necessary to use a "multivariable" method for a better prevision of the cutaneous changes after facial osteotomies, specially for the lips. Indeed, vertical soft tissue changes are the result of the interactions of many vertical and horizontal surgical squelettal displacements.
