“…A double contour of the condylar head and/or the mandibular fossa has been reported to be a specific radiographic indication of remodeling activity, and this distinct double contour, specifically in the posterior area of the condylar head, was found in most of the joints studied in that report 8. Condylar remodeling has also been reported in other long-term post-operative radiographic examinations 9. However, only a few studies have utilized cone-beam computed tomography (CBCT) to investigate physiologic condylar head remodeling after orthognathic surgery in cases involving skeletal class III deformity 5…”

“…Further studies with larger sample sizes and control subjects should be performed to elucidate these findings. Several computed tomography studies suggested that the degree of postoperative condylar long-axis alteration might be a predictive factor of condylar remodeling 5,8,9,19,20. The movement associated with this alteration imparts compressive loading to the condyle and glenoid fossa, which could be one of factors related to condylar remodeling.…”

ObjectiveTo evaluate condylar head remodeling after mandibular set-back sagittal split ramus osteotomy (SSRO) with rigid fixation in skeletal class III deformities. The correlation between condylar head remodeling and condylar axis changes was determined using cone-beam computed tomography (CBCT) superimposition.MethodsThe CBCT data of 22 subjects (9 men and 13 women) who had undergone mandibular set-back SSRO with rigid fixation were analyzed. Changes in the condylar head measurements and the distribution of the signs of condylar head remodeling were evaluated by CBCT superimposition.ResultsThe subjects showed inward rotation of the axial condylar angle; reduced condylar heights on the sagittal and coronal planes; and resorptive remodeling in the anterior and superior areas on the sagittal plane, superior and lateral areas on the coronal plane, and anterior-middle and anterior-lateral areas on the axial plane (p < 0.05).ConclusionsThe CBCT superimposition method showed condylar head remodeling after mandibular set-back SSRO with rigid fixation. In skeletal class III patients, SSRO with rigid fixation resulted in rotation, diminution, and remodeling of the condylar head. However, these changes did not produce clinical signs or symptoms of temporomandibular disorders.

“…Glenoid fossa remodeling has been studied after condylectomy (54, 55), condylar fractures (56, 57), TMJ surgical procedures (58), permanent tooth loss (59) and occlusal equilibration (60). Studies have documented the adaptive mechanism of the TMJ in animals following mandibular advancement histologically (5–19, 61–63), through the altered levels of biochemical messengers (64–66) and through altered gene expression (67–70).…”

Sagittal split ramus osteotomy(SSRO)is widely used for skeletal mandibular prognathism, but various changes are seen after SSRO. Changes in the position of the mandible immediately after surgery can lead to unstable occlusion and prolonged orthodontic treatment. The aims of this study were to examine the changes in the positions of the proximal fragment and the condylar head of the mandible and to investigate the morphological changes in the condylar head of the mandible using CT images acquired before SSRO(BO)and 1 month(AO1)and 6 months(AO6)after SSRO. 1. Significant changes in the axial condylar angle were found at BO-AO1 and at BO-AO6.However, significant changes in measurements on the coronal plane were not found at BO, AO1, or AO6. Significant changes in the distance between the mandibular fossa and the condylar head of the mandible on the axial plane were also not found at BO, AO1, or AO6. 2. There were significant differences in the proximal fragment along the X-axis and Z-axis from BO to AO1. There was no significant difference in the proximal fragment from AO1 to AO6. 3. The height(SH and CH)of the condyle was significantly decreased from AO1 to AO6. 4. Changes of the proximal fragment along the X-axis were correlated with the width of the condyle, and changes along the Y-axis were inversely correlated with height, sagittal width, and axial width of the condyle. Changes of the proximal fragment along the Z-axis were inversely correlated with the axial width of the condyle. 5. Reductional bony change was found in areas B, C, E, and F, while additional bony change was found in areas B and G.In conclusion, external and superior displacement of the proximal fragment and positional changes of the condylar head of the mandible due to external, superior, and internal rotation often occurred immediately after SSRO. It was suggested that bone remodeling was found from the external surface of the condylar head of the mandible to its antero-superior aspect.
