“…6,7 Many other studies have reported on postoperative condylar changes as well. [8][9][10] For assessment of condylar remodeling, several CBCT-based analysis methods have already been introduced. 11,12 Carvalho et al 13 evaluated 3D changes of location in the ramus, condylar, and mental region in patients who had received mandibular advancement.…”

Objective: To evaluate the effect of postoperative condylar axis changes on mandibular condylar remodeling by comparing the condylar head in three-dimensional (3D) surface reconstructions before and after surgery in skeletal Class III deformities (one-jaw [mandibular setback] or two-jaw surgery), and also to determine the relationship between condylar inward rotation and condylar surface remodeling after orthognathic surgery. Materials and Methods: A retrospective analysis was conducted of 30 patients with skeletal Class III deformities who had received orthognathic surgery. Group 1 underwent one-jaw surgery (10 men, five women, age 22.4 6 3.3 years), and group 2 underwent two-jaw surgery (10 men, five women, age 22.3 6 2.2 years). Sixty condyles were reconstructed and superimposed pre-and postoperatively to compare the changes of condylar surfaces. The relation between the condylar axis change and the surface change using the Pearson correlation were investigated from the 3D image software. Results: Condylar surface changes before and after the surgery were significant. The postoperative inward rotation of the condyles was correlated with the average absolute deviation of the condyles, regardless of the surgery type (one-or 2-jaw surgery; r 5 .70, P , .05). Conclusion: After orthognathic surgery, condylar surface changes occurred, and condylar inward rotation was closely related to changes of condylar surface. (Angle Orthod. 2014;84:316-321.)

“…The mandible or bi maxillary surgery could modify the condylar position and be a factor for CR; in mandible surgery, statistical differences were not observed between the pre-surgical and post-surgical position of condyle (Ueki et al, 2002;Fang et al, 2009;Hackney et al, 1989; but this difference could be a clinical significance in the postoperative condition. On the other hand, Baek et al (2006) showed that in asymmetric movement (using sagittal split ramus osteotomy) the condylar position was the same after and before of surgery but with differences in inclination of condylar head of major and minor movement; this situation can be an explanation for different load on the condylar head and consecutively bone reabsorption.…”

SUMMARY:The aim of this research was to evaluate the risk factors related to condylar resorption (CR) after orthognathic surgery. Was realized a systematic review with a search of the literature performed in the electronic databases PubMed, MedLine, Ovid, Cochrane Library for current evidence in the world literature as conducted, and relevant articles were selected in according to inclusion and exclusion criteria and the findings were compared. Eight papers, (follow-up 12 months to 69 months) were including. A sample of 2567 patient with mandible or bi maxillary surgery with an age range from 14 to 46 year old was observed. In 137 patients (5.3%) CR was observed , with a 97.6% (122) female. CR was related to 118 cases with mandibular deficiencies with high mandibular plane (advancement surgery). CR were present principally in bi maxillary surgery with a 103 cases (75.2%) and only two papers show any analysis to the relation with TMJ dysfunction. Current evidence in CR is poor but supports those female patients with mandibular deficiency and high mandibular plane angle submitted to bi maxillary surgery with change in occlusal plane (counterclockwise) are associated with condylar resorption after orthognathic surgery.
