[Radiographic scanning of the temporomandibular joint. Technic and results].
The authors report a prospective study involving investigation of the temporo-mandibular joints for algo-dysfunctional syndromes by gaseous arthroscanning. They propose a double articular compartment injection technique using CT scan localization. The CT scan study is performed using fine sagittal sections with the mouth both closed and open, and also Hirtz coronal sections. Early results directly demonstrate menisco-ligamentary structures, the position of the meniscus in the closed position and its displacement on mouth opening, these being of fundamental importance to the practitioner. The authors present normal results and the principal pathological results encountered in the investigation of algodysfunctional syndromes involving this joint (T.M.A.D.S.). CT scan allows more precise localization for joint injection than radioscopy, and while the images obtained are markedly better than those obtained on opaque arthrograms, they offer less dynamic information in view of the lack of radioscopy.
