     SUMMARY

    In progenia surgery it is very important that condyle retains its preoperative position in the fossa. Condylar displacement with axial rotation has an important role in idiopathic condylar resorptions after sagittal osteotomy. The paper addresses condylar position after progenia operations in 24 patients. Axial x-rays of the mandible were taken in all patients. Fragment imobilisation was done with mini-plates. In 7 cases, those were straight-plates and in 17 cases bent-plates were used. Condylar displacement in relation to the preoperative position was noted in only 3 patients with rigid fixation (all straight-plate cases). Though the study group was small, the results indicate that axial x-ray of the mandible can be a useful tool in condylar position assessment after progenia surgery.
