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