Résorption condylienne après chirurgie orthognathique : étude rétrospective sur 40 patients au CHU de Caen

Abstract : Condylar resorption is a progressive alteration of the shape and volume of the mandibular condyle. It happens after orthognathic surgery, following the constraints exercised on the condyle during the intervention. In order to limit the latter, while facilitating the correction of occlusion intraoperatively, several adjustable mini-plates of osteosynthesis have been developed. Material and method: a retrospective study, between January 2014 and December 2017, was performed in the Maxillofacial Surgery Department of the University Hospital of Caen, on patients who underwent mandibular osteosynthesis in orthognathic surgery using mini-plates S-shaped (MATERIALISE®). The primary endpoint was evaluation of late-postoperative CR. Results: among the 40 patients included, there was a significant decrease in mandibular crunches postoperatively. Only one patient showed radiographic signs of CR with a decrease in the height of the condyles more than 2 mm and a decrease in the ram height more than 6%. Morphologically, the condyles did not show any significant change in the dental panoramic analysis. Conclusion: the S-chaped plates, practical and easy to use, do not seem to provide RC. Further study with CT data would be necessary to complete the accuracy of this work.
